Civil 3D 2020.1 Update

Autodesk has released the long waited 2020.1 update. See below for new features, fixed issues, and known issues…

The Autodesk® Civil 3D® 2020.1 Update contains the following new features and enhancements.

Design Efficiency Updates

  • Create, edit, and export rail lines using the following commands on the Rail ribbon tab:

    You can create dynamic 3D polylines or feature lines from a rail alignment that represent the left, center, and right rail lines.

    • The rail lines are created with common stationing based on a specified tolerance or interval, and they dynamically adjust to modifications to the parent rail alignment, profile, and cant.
    • Rail line station data can be exported to a CSV file for design validation and for use in other applications.

  • For more information, see Rail Lines.

  • French and German design rules are now available for rail platform edge creation.

    When you are creating a rail platform edge, you can select France_Metric.json or Germany_Metric.json as the design rule file to use. For more information, see Create/Edit Platform Edge Dialog Box.

  • The rail turnout catalog has been extended to include French turnouts based on SNCF standards.
    Note: To access the updated rail turnout catalog after installing this update, make a backup copy of C3D_TurnOut.xml in C:\ProgramData\Autodesk\C3D 2020\enu\Data\Railway Design Standards\ and then delete C3D_TurnOut.xml. When you use a turnout command, the updated C3D_TurnOut.xml file will be copied from the installation folder to the Railway Design Standards folder.
  • Use new options for viewing pressure networks in profile view.
    • Options are now available in the fitting and appurtenance styles to display the parts as boundaries, catalog-defined blocks, or user-defined blocks. You can also select options to mask underlying parts, to crop parts at the profile view extents, and to hatch parts in profile view.
      Part boundary in profile view Part masking enabled Part cropped at profile view extents Hatching displayed on part

      The options for displaying the parts as boundaries or blocks and the options for masking and cropping are available on the new Profile tab of the fitting and appurtenance style dialog boxes. For more information, see Profile Tab (Fitting Styles Dialog Box) and Profile Tab (Appurtenance Style Dialog Box).

      The hatching option is available on the Display tab of the fitting and appurtenance style dialog boxes. For more information, see Display Tab (Appurtenance Style Dialog Box) and Display Tab (Fitting Style Dialog Box).

    • You can now add band styles to profile views to display information about pressure networks in profile views.
  • Use the following enhancements in the Analyze Gravity Network command:
    • Compute Energy and Hydraulic Grade Lines is now the default analysis type.
    • Storm drain data is now included in a report when Compute Energy and Hydraulic Grade Lines is selected as the analysis type.
    • The specified Tailwater Condition now remains selected when re-running the analysis on the same pipe network.
    • The pipes in the current parts list can be selected from a drop-down list on the Network Details page.
      Note: When resizing a pipe network using the Resize Pipes and Reset Inverts analysis type, part sizes are added to the parts list from the catalog if required. For more information, see About Analyzing and Sizing a Gravity Pipe Network.
    • Use the new drainage structure parameter mapping feature to map the parameters of Part Builder parts to parameters that are required for the Analyze Gravity Network command.

      By setting up and applying the mapping for these parts, the parameter values will be available within the Analyze Gravity Network command by default.

      For more information, see To Map Drainage Structure Parameters for Gravity Network Analysis.

      Note: Parts created with the Infrastructure Parts Editor already have the parameters that are required for the Analyze Gravity Network command and do not require mapping.
    • Multiple catchments per structure are now supported for gravity network analysis.
      • The Connections tab in the Structure Properties dialog box now has a Connected Catchments section that shows which catchments are connected to the structure.
      • In the Analyze Gravity Network dialog box, the combined area, longest time of concentration, and the weighted runoff coefficient are displayed for the catchments and these values are used in the analysis calculations.
    • Catchment information can now be defined directly in the Structure Properties dialog box and in the Analyze Gravity Network dialog box.
      • You can enter catchment information directly on the Connections tab in the Structure Properties dialog box by defining values in the Area, Time of Concentration, and Weighted Runoff Coefficient fields.
      • You can also enter catchment information directly on the Network Details page of the Analyze Gravity Network dialog box by entering 2D Area, Runoff Coefficient, and Time of Concentration values.

Production Efficiency Updates

  • Use enhanced reference template features to manage styles and settings.
    • You can set up a reference template in advance to control which components in the template will be referenced into a host drawing.

      When you have a drawing DWT file open, the new Set Reference Template Defaults command is available on the Styles panel.

      Use this command to set up a reference template. Only the items that are selected when you set up the reference template will be referenced into the host drawings by default. For more information, see To Set Up a Reference Template.

    • When you attach an additional reference template to a drawing, you are alerted to duplicates with warning symbols and tooltips.

      To change which component is used, you can change template priority, or you can clear the selection in the higher priority template so that the component in the lower priority template is used.

      For more information, see To Set Up a Reference Template.

    • You can use a new value in the AeccRefTemplateAutoUpdate system variable to prevent layer properties in host drawings from being overwritten by reference templates.

      By setting the variable value to 2, changes you make to layer properties in host drawings will not be overridden by the reference templates. For more information, see To Work With Reference Templates.

  • The Manage Data Shortcuts command has been updated with the following features for specifying a different data shortcut project path when the current path is still valid:
    • If there is another valid path to a data shortcut project available, you can specify that path by browsing to the alternate data shortcut Source File or Path from the Data Shortcut Manager dialog box.

      After selecting the alternate Source File or Path, a dialog box is displayed which you can use to update the shortcuts. Drawing objects that reference the original path will be updated to reference the alternate path.

    • You can also specify an alternate valid path as the working folder, and then you can use the Link button in the Manage Data Shortcuts dialog box to change the links to the objects. Previously, if you attempted to use the Link button to change the link to a different valid path, the Event Viewer would display a message that the reference already existed.
  • Use a new system variable named PipeNetworkSyncMode to control the synchronization of data referenced pipe networks when you open a host drawing. You can use the following settings for PipeNetworkSyncMode:
    Value Description
    0

    If the geometry of a pipe network has been changed in the source drawing, the data referenced pipe network will be synchronized automatically when you open the host drawing.

    1

    If the geometry of a pipe network or the names or descriptions of the pipes or structures have been changed in the source drawing, the data referenced pipe network will be synchronized automatically when you open the host drawing.

    Note: This is the default setting.
    2

    A data referenced pipe network will always be synchronized automatically when you open a host drawing, regardless of whether the pipe network has been changed in the source drawing.

Collaboration and Data Exchange Updates

  • Use the following features to bring ArcGIS data into your Civil 3D drawings and to save back, publish, and export data for use in ArcGIS.
    • Autodesk Connector for ArcGIS: Bring ArcGIS data into your Civil 3D drawings using the Autodesk Connector for ArcGIS. Sign in to ArcGIS and then specify an area of interest, a dataset to use, and the Civil 3D object types to create from the ArcGIS data. For more information, see To Bring ArcGIS Data into Civil 3D.
    • Data Source Manager: Save edited Civil 3D objects back to ArcGIS and remove datasets. For more information, see To Manage ArcGIS Datasets in a Drawing.
    • Publish to ArcGIS: Publish Civil 3D objects to ArcGIS. Sign in to ArcGIS and then specify the Civil 3D objects to publish, define layers, add tags, and specify the publishing location. You can also specify whether to share the published content with your ArcGIS groups and whether it will be editable. For more information, see To Publish Civil 3D Objects to ArcGIS.
    • Export to FGDB: Export Civil 3D objects to a file geodatabase (FGDB) that can be used in ArcGIS. Specify the Civil 3D objects to export and then specify the name and location for the file geodatabase. For more information, see To Export Civil 3D Objects to File Geodatabase (FGDB) Format.
  • Export feature lines to LandXML files and use enhanced methods for importing feature lines from LandXML files.
    • You can now export feature lines to LandXML files, including feature lines that are created from alignments and corridors.
      Note: Feature lines cannot be exported to LandXML files directly from an alignment or a corridor and must be created from the objects first before they can be exported.

      For more information, see Export Tab (LandXML Settings Dialog Box).

    • Exported feature lines created from an alignment remain dynamic to the parent alignment when the alignment is exported and imported along with the feature lines.

      For more information, see Export Tab (LandXML Settings Dialog Box).

    • You can now import feature lines on the site specified in the LandXML source file by selecting an option in the LandXML Settings dialog box.

      For more information, see Import Tab (LandXML Settings Dialog Box).

    • Importing surface breaklines as feature lines has been enhanced to preserve the dynamic nature of the breaklines. After a LandXML file is imported into a drawing, you can edit the feature lines that were created from the breakline data and the corresponding surface will update.

      For more information, see Import Tab (LandXML Settings Dialog Box).

Other Updates

  • The behavior of some of the overlay slope options in the corridor rehab subassemblies has been updated.
    • The behavior of the User Defined With Flapping parameter has changed in situations within slope tolerance and outside of slope tolerance.
    • The behavior of the User Defined Without Flapping and Inside/Outside Lane Superelevation parameters has changed in situations outside of slope tolerance.

    For more information, see Updates to the Corridor Rehab Subassemblies.

  • Reports are now available on the Toolbox tab of Toolspace for reporting parcel information in a counter-clockwise direction.

This document lists known issues in Autodesk Civil 3D 2020.1.

Data Shortcuts
Autodesk Civil 3D 2020.1 does not support data shortcut projects that are located on connected drives or on other cloud data storage devices.
Esri ArcGIS Data Workflows
It is not supported to save back gravity pipes that are created from ArcGIS lines that have multiple segments. When you bring an ArcGIS line that has multiple segments into Civil 3D as gravity pipes, each line segment becomes a unique pipe in Civil 3D. If you use the Save Back command to save back the pipes to ArcGIS, only a single line segment will be saved back, and the other line segments will be removed from ArcGIS.If you make changes to such a pipe network in Civil 3D, instead of using the Save Back command, you can use the Publish to ArcGIS command to publish the pipe network to ArcGIS. Alternatively, you can bring the ArcGIS dataset into Civil 3D as feature lines. If you save back feature lines that were created from ArcGIS lines that have multiple segments, all the line segments are saved back to ArcGIS.
If you enter “ArcGIS” at the command line, the available command list that is displayed includes AeccConnectToArcGISData. Selecting that command will result in an unknown command message because that command has been replaced with the ArcGISConnector command in Autodesk Civil 3D 2020.1.
LandXML
Rail line feature lines and rail platform edge feature lines do not remain dynamic to their parent alignments if they are exported to LandXML with their parent alignments and then reimported with their parent alignments into a drawing.
Rail
The rail turnout catalog has been extended to include French turnouts based on SNCF standards. To access the updated rail turnout catalog after installing Autodesk Civil 3D 2020.1, make a backup copy of C3D_TurnOut.xml in C:\ProgramData\Autodesk\C3D 2020\enu\Data\Railway Design Standards\ and then delete C3D_TurnOut.xml. When you use a turnout command, the updated C3D_TurnOut.xml file will be copied from the installation folder to the Railway Design Standards folder.If you uninstall the update, delete the C3D_TurnOut.xml file in the Railway Design Standards folder. The next time you use a turnout command, the C3D_TurnOut.xml file will be copied from the installation folder to the Railway Design Standards folder.
Reference Templates
You can set the AeccRefTemplateAutoUpdate system variable value to 2 to prevent layer properties in host drawings from being overwritten by reference templates. If you change the variable value back to 1, layers are not referenced into the host drawing until a reference template is reapplied.To reapply a template, open the Attach Referenced Template dialog box and then make any change such as clearing and re-selecting a check box, and then click Apply.
To ensure that new feature settings are included in a reference template that was created in a previous version of Civil 3D, open the reference template DWT or DWG file in Civil 3D 2020.1 and save it. Otherwise, new feature settings might be missing in host drawings that reference the template when the host drawings are opened in Civil 3D 2020.1.
Parcel styles and point table styles are not available for selection in the Set Reference Template Defaults dialog box and will be referenced by default. Any components (such as layers) that these styles are dependent upon will also be referenced by default and cannot be deselected.
Reports
If you had a beta build of Civil 3D 2020.1 installed, after uninstalling the beta build and installing Civil 3D 2020.1, the Parcel_CCW reports will not be available on the Toolbox tab of Toolspace. As a workaround, after uninstalling the beta build, repair Civil 3D 2020 and then install Civil 3D 2020.1.

Civil 3D 2020: What’s New?

Autodesk® Civil 3D® 2020 contains the following new features and enhancements:

Design Efficiency Updates

  • Use the updated Analyze Gravity Network command to analyze a pipe network and apply the results to the pipe network.

2019-04-15_0929

The updated command uses a modeless dialog box so you can leave it open while you do other work.

You can use this command to perform the following analysis types:

  • Resize Pipes and Reset Inverts: Analyzes the flow through the pipes, and then resizes the pipes and resets inverts to accommodate the flow.
  • Compute Energy and Hydraulic Grade Lines: Calculates the energy and hydraulic grade lines, and reports whether each line in the system is in a normal state, surcharged, or flooded.
  • Inlet Analysis: Analyzes the capacity of the inlets and reports the flow, depth, and spread at each inlet.

Use new structure feature settings to specify default values that can be used by the Analyze Gravity Network command…

2019-04-15_0930

  • Autodesk Storm and Sanitary Analysis has been updated with the following features:
    • Tailwater conditions can be set separately for each storm while running multiple storm events.
    • The Peak Rate Factor for a dimensionless hydrograph can be set for each subbasin.
    • New and updated storage chambers from Advanced Drainage Systems® (ADS) and CULTEC® are available.
  • In alignment reports for alignments which use chord-based stationing, chord-based calculations are now used to report the station values and the end station.
  • Chinese design standards are now supported for rail platform design. You can select the China_Metric.json design criteria file when creating or editing a rail platform edge. For more information, see Create/Edit Platform Edge Dialog Box.

Production Efficiency Updates

  • Use the Autodesk Dynamo for Civil 3D commands to develop and run scripts for automating tasks and workflows in Autodesk Civil 3D.
    Autodesk Dynamo for Civil 3D is a visual programming application that is available as a separate installation through the Autodesk Desktop App and from your Autodesk Account.
  • After you install the application, the Dynamo-related commands are available on the Manage ribbon tab in Civil 3D.

2019-04-15_0930_001

  • When you attach an additional reference template to a drawing, it is now added to the bottom of the list of templates, and customized settings that have already been specified for the previously-attached templates are preserved.

2019-04-15_0930_002

  • Use a new system variable named SyncDrefPsetToSource to control whether property sets are synchronized when you synchronize data shortcut references. You can use the following settings for SyncDrefPsetToSource:

0        Property sets will never be synchronized when related data referenced objects are  synchronized.

1        Property sets will be synchronized when related data referenced objects are synchronized.

Property set synchronization will occur in the host drawing only if the object has been changed in the source drawing.

  • If the object has been changed in the source drawing, the object and the related property set will be synchronized in the host drawing.
    If the object has not been changed in the source drawing, the object and the related property set will not be synchronized in the host drawing.
    Note: If the property set has been changed in the source drawing, the property set will not be synchronized unless the object has been changed in the source drawing.
  • Data shortcut synchronization related to superelevation and cant changes has been enhanced. With this enhancement, changes to more types of superelevation or cant parameters in a source alignment will prompt you to synchronize a data referenced alignment.

Collaboration and Data Exchange Updates

  • The Export Civil 3D Drawing command has been updated with the following features:
    • Labels with background masks are no longer exported with bowtie-shaped hatches.
    • Xrefs are exploded appropriately on export.
    • Proxy state messages are no longer displayed on export.
    • The option to convert feature lines, parcel segments, and survey figures to 2D or 3D polylines that was included in the Autodesk Civil 3D 2019.2 Update is included in Autodesk Civil 3D 2020.
  • Use a new setting to control whether rail alignments are exported from Autodesk Civil 3D for use in Autodesk InfraWorks as centerline alignments or rail alignments.

2019-04-15_0930_003

  • When set to No, a rail alignment exported to IMX from Civil 3D will become a railway object in InfraWorks which can cause it to lose some of the accuracy of its geometry.
  • When set to Yes, a rail alignment exported to IMX from Civil 3D will be exported as a centerline alignment and will become a component road when it is brought into InfraWorks. The component road will have the same geometry as the rail alignment in Civil 3D.

Note: This setting is applicable when using the Export IMX command in Civil 3D and when opening a Civil 3D drawing directly in InfraWorks.

Other Updates

  • The Dark color scheme and the application ribbon icons have been updated.
    • The Dark color scheme that controls the appearance of the application window, ribbon, and other user interface elements has been updated with new colors.
    • Ribbon icons for both the Light and Dark color schemes have been updated for style and clarity, optimized to work with the background colors, and updated to scale with high-resolution monitors.
  • The survey database format has been updated from Microsoft SQL Server Compact (SQL CE) format to SQLite. To use existing survey databases with Autodesk Civil 3D 2020, they must be converted to SQLite.
    Use the Autodesk Civil 3D Survey Database Migration Utility to convert survey databases from SQL CE to SQLite.

  • Add crossing objects to profile views to show where linear objects cross the profile relative to the parent alignment.
  • Enter folder paths, including UNC paths, directly into the Folder field in dialog boxes that prompt for a folder location.

Collaboration and Data Exchange Updates from the Autodesk Civil 3D 2019 Update Releases

  • Publish surfaces to Autodesk® BIM 360™ Document Management for use in Autodesk® Revit®.
  • Use updated LandXML import and export features when importing or exporting data. Import and export rail cant data, import breaklines as either feature lines or as 3D polylines when importing surface data from LandXML files, and specify whether property set definitions are created and applied when surface data is imported from a LandXML file.
  • Update existing object data in a drawing and create property set data when importing LandXML files.
  • Specify whether the Export Civil 3D Drawing command converts feature lines, parcel segments, and survey figures to 2D or 3D polylines.

Civil 3D 2018.3 Update

Autodesk has released the Civil 3D 2018.3 update. Below is a list of enhancements and fixes:

The following enhancements have been included in the Autodesk AutoCAD Civil 3D 2018.3 Update:

Design Efficiency Updates

  • You can now specify the maximum rate of change for the superelevation cross slope of an alignment in the Edit Feature Settings – Alignment dialog box.

Production Efficiency Updates

  • Data shortcut synchronization related to superelevation and cant changes has been enhanced. With this enhancement, changes to more types of superelevation or cant parameters in a source alignment will prompt you to synchronize a data referenced alignment.
  • You can use a new system variable named SyncDrefPsetToSource to control whether property sets are synchronized when you synchronize data shortcut references. You can use the following settings for SyncDrefPsetToSource:
    • 0: Property sets will never be synchronized when related data referenced objects are synchronized.
    • 1: Property sets will be synchronized when related data referenced objects are synchronized.

Collaboration Efficiency Updates

  • You can use a new option in the Export Settings dialog box to specify whether to convert feature lines, parcel segments, and survey figures to 2D polylines or to 3D polylines when exporting a drawing with the Export Civil 3D Drawing command.Note: For information about additional updates to the Export Civil 3D Drawing command, see Primary Issues Resolved by This Update.

AutoCAD 2020: What’s New

Below is a list of what’s new in AutoCAD 2020 taken from the HELP guide. Keep an eye out for the new release to show up in your Desktop App, and manage.autodesk.com website.

AutoCAD 2020 provides a set of enhancements based on customer feedback, surveys, and analytic data that prioritize our efforts. Several features modernize and streamline frequently used features across many customer disciplines.

New Dark Theme

Your user interface is obviously something that you use all the time. Past customer feedback repeatedly indicated that we needed to make significant changes to improve the clarity and crispness of the dark theme. Similar sharpening was also applied to the light theme as well.

As you can see, we optimized the background colors with the icon colors to provide the optimum contrast without distracting from the drawing area, where you’re usually focused.

The highlighting of contextual tabs on the ribbon is now more distinct when active, such as when you edit text or create a hatch.

Ribbon Access

Application button > Options > Display tab > Window Elements > Color Theme

Blocks Palette

Several methods for inserting blocks are currently available: Insert, Tool Palettes and DesignCenter. Having these different options available recognizes that people in different disciplines have different requirements and preferences.

The primary reason for redesigning the Insert dialog box is to provide better visual previews of blocks in the workflow for inserting blocks. The palette increases efficiency for finding and inserting multiple blocks-including the new Repeat Placement option, which can save you a step.

Key features in the new Blocks palette facilitate specifying and inserting blocks efficiently from a most recently used list or from specified drawings. Three tabs provide access to the following:

  • The Current Drawing tab displays all the block definitions in the current drawing either as icons or as a list.
  • The Recent tab displays all the most recently inserted blocks regardless of the current drawing. These persist between drawings and sessions. You can remove a block from this tab by right clicking it and choosing Remove from Recent List.
  • The Other Drawing tab provides a way of navigating to folders from which you can choose drawings either to insert as blocks or to choose from the blocks defined in those drawings. These drawings and blocks also persist between drawings and sessions.

The top of the palette includes several controls, including a field for applying wildcard filters to the block names, and several options for different thumbnail sizes and list styles.

Ribbon Access

Home tab > Block panel > Insert.

Access from the ribbon provides a gallery of the blocks available in the current drawing together with two new options, Recent Blocks and Blocks from other Drawings.

These two options open the Blocks palette either to the Recent tab or the Other Drawing tab. The Current Drawing tab in the Blocks palette displays the same blocks in the current drawing as the ribbon gallery. Placing blocks from the Blocks palette can be accomplished by dragging and dropping or clicking and placing.

New and Changed Commands

BLOCKSPALETTE – Opens the Blocks palette.

BLOCKSPALETTECLOSE – Closes the Blocks Palette.

CLASSICINSERT – Opens the classic Insert dialog box.

INSERT – Starts the BLOCKSPALETTE command except in scripts, which open the legacy INSERT command for script compatibility.

-INSERT – Starts the command line version of the classic INSERT command.

New System Variables

BLOCKMRULIST – Controls the number of blocks displayed in the Recent tab of the Blocks palette.

BLOCKNAVIGATE – Controls the file and blocks that are displayed in the Other Drawing tab of the Blocks palette. Takes effect the next time you start the program.

BLOCKREDEFINEMODE – Controls whether the “Block- Redefine Block” task dialog box is displayed when inserting a block from the Blocks palette with the same name as a block inside the current drawing.

BLOCKSTATE (Read only) – Reports whether the Blocks palette is open or closed.

Purge Redesign

The Purge feature has been revised for easier drawing cleanup and organization. The control options are nearly the same, but the orientation is more efficient and the Preview area is now resizable.

  • Notice that you can now purge zero-length geometry without purging empty text objects.
  • Check boxes in the Named Items Not Used panel provide a way to select purgeable items by category as well as individual items.
  • The Find Non-Purgeable Items button displays information specific to why the checked item cannot be purged, which will be helpful in many cases.
  • For objects that can’t be purged, the new design provides enhanced information as shown below, including the number of objects on each layer and their impact on file size. The Select Objects button shown in the illustration below, zooms in on the specified objects that can’t be purged.

Ribbon Access

Manage tab > Cleanup panel > Find Non-Purgeable Items and Purge.

These two controls determine whether the Purgeable Items or Find Non-Purgeable Items display when the Purge dialog box opens.

Changed Commands

PURGE – Opens the redesigned Purge dialog box.

DWG Compare Enhancements

The primary enhancement to the DWG Compare feature is that you can now directly compare and edit the current drawing together with a specified drawing while in the compare state. The comparison takes place in the current drawing. Any changes you make in either the current drawing or the compared drawing are dynamically compared and highlighted.

To facilitate direct editing in the compare state, the options and controls for this feature were moved from the ribbon to a docked toolbar at the top of the drawing area. Most of the options were combined into the Settings control and enhanced as shown. You can easily toggle the comparison from the toolbar and the display of the types of differences from the Settings control.

Also, the default colors can easily be changed by clicking on a color for your preferences or for colorblind-friendly colors. In this illustration, the color for Not in Current Drawing was changed from red to yellow.

For example, let’s say you need to compare the differences between two highly complex drawings that have been simplified to look like the following:

The result of comparing the current drawing with the compared drawing looks like this:

The change sets are each surrounded by orange revision clouds, which are scaled to the drawing extents.

  • You can import the highlighted differences in yellow from the compared drawing into the current drawing. If you do so, these objects will now exist in both drawings and will automatically turn gray. Only the objects in the specified area that are not in the current drawing can be imported.
  • You can also export both drawings into a new snapshot drawing that combines the similarities and changes between both drawings. The result of this operation is the same as a drawing comparison in AutoCAD 2019.
  • The arrow buttons provide a way to step through each change set, automatically zooming in to each successive or previous change set.

Toolset-Specific Limitations

The following tables describe how certain objects are affected when imported during a comparison with drawings created using the AutoCAD Electrical and AutoCAD Mechanical toolsets.

AutoCAD Electrical toolset objects Result after a compare import operation
Wires Wires will lose some properties such as color and size. The wire data is available in the project as layers and cannot be imported into the drawing comparison mode.
Wire number The wire number is disconnected with the wire. The imported wire number will lose its relationship with the wire.
Source/Destination arrows The source and destination arrows imported will not have the correct wire numbers. The source arrows and the destination arrows will also lose their relationship to each other.
Schematic terminals These blocks will retain their electrical properties, however the terminal wire numbers will not be updated.
Balloons The imported balloons will not be grouped and will be available only as exploded geometric objects.
AutoCAD Mechanical toolset objects Result after a compare import operation
Mechanical symbols Importing a mechanical symbol that’s attached to an object also imports the associated object. For example, if a weld symbol is attached to a rectangle, importing the weld symbol will also import the rectangle object.
Standard parts Importing a standard part will not update the Bill of Materials (BOM) unless you also select the associated part reference of the standard part.
Finite Element Analysis (FEA) objects and other calculation objects Importing an FEA object will not include its mechanical data and the object will be imported as a block.

Ribbon Access

Collaborate tab > Compare panel > DWG Compare.

New Commands

COMPARECLOSE – Closes the Compare toolbar and exits the comparison.

COMPAREEXPORT – Exports the comparison results into a new drawing, called a snapshot drawing, and opens the drawing.

COMPAREIMPORT – Imports objects from the compared file into the current drawing. Only the selected objects that exist in the compared file and not in the current file are imported.

New System Variables

None.

Measure Geometry Option: Quick Measure

Measuring has become much faster with the new Quick option of the MEASUREGEOM command. With this option, you can quickly review the dimensions, distances, and angles within a 2D drawing.

When this option is active, the command displays dimensions, distances, and angles within a 2D drawing dynamically as you move your mouse over and between objects. The orange squares displayed at the left side of the illustration represent angles at precisely 90 degrees.

The distance between the two objects is measured in the illustration below because they’re parallel.

Tip: To avoid quick dimension clutter and to improve performance, it’s best to zoom into complicated areas.

Ribbon Access

Home tab > Utilities panel > Measure/Quick.

Changed Commands

MEASUREGEOM – Adds the Quick option for real-time measurements.

New System Variables

None.

Performance Improvements

A new installation technology dramatically improves the install time on solid state drives (SSD), typically reducing the time by about half.

Network access time to xrefs, blocks, and support files has been improved. Support files include those associated with hatches, tool palettes, fonts, linetypes, template files, standards files, and so on. The degree of improvement depends on the size and content of your drawing files and network performance.

Support for Cloud Services

AutoCAD 2020 now supports cloud connectivity and storage with several cloud service providers when you use the Save, Save As, and Open commands.

Depending on what you have installed, the Places list in AutoCAD file selection dialog boxes can include Box, Dropbox, and several similar services.

Save to Web & Mobile Enhancements

AutoCAD 2020 includes additional support for AutoCAD Web and AutoCAD Mobile. The enhancements are as follows:

  • Includes Xrefs with the drawing files that you save for AutoCAD web and mobile access.
  • The CAD Manager Control Utility includes a new checkbox on the Online Content tab to disable the SAVETOWEBMOBILE and OPENFROMWEBMOBILE commands. This control has been added for sites that require their drawings to remain exclusively within their organization’s network.

Access

Quick Access toolbar > Save to Web & Mobile and Open from Web & Mobile commands as shown below:

Graphics Configuration

AutoCAD now launches correctly with different DirectX drivers (Dx9, Dx11, or no driver), high resolution (4K) monitors, and dual monitors. In addition, the graphics display settings are consolidated into three modes, which includes gradient hatches and images. The graphics performance setting, Intermediate Mode, is updated to reset several display parameters automatically to optimize your display.

Access

Enter GRAPHICSCONFIG at the Command prompt.

The Graphics Performance dialog box displays, shown in part below.

Changed Commands

GRAPHICSCONFIG – Revised 2D Display Settings as displayed in the Graphics Performance Dialog Box.

-GRAPHICSCONFIG– Revised command line options that support the new 2D Display Settings.

Security Enhancements

Following are highlights of the work completed in AutoCAD 2020 relating to cyber security. Due to the sensitive nature of some of these fixes, we’ve deliberately avoided providing overly specific descriptions.

  • Four potential exploits in certain data files created by AutoCAD have been closed.
  • Several dependencies on DLLs or other components used in AutoCAD with known vulnerabilities were removed or upgraded.
  • A future vulnerability in a component is in process of being replaced.
  • A potential server vulnerability has been closed with an upgrade.

Because your work and intellectual property are frequently targeted by cyber criminal and other organizations, it’s always important to keep up with the latest product, network, and operating system upgrades, cyber security enhancements, and fixes. Autodesk continues to monitor cyber threats and strives to deliver products that conform to current and anticipated security requirements.

Civil 3D 2016.0.5 Update

Autodesk has released a new update for Civil 3D 2016. The updated includes the following fixes:

  • Civil 3D no longer closes unexpectedly drawing a circle using a some linetypes.
  • An issue has been resolved that resulted in annotations along parcel segments to be created incorrectly.
  • As issue that resulted in lines to display inconsistently after using the REGEN or REGENALL command has been resolved.
  • An issue where linetypes are not scaled as expected when an alignment mask is used has been resolved.
  • When importing an expression into a drawing, and issue where the expression is not updated if the expression already exists in the destination has been resolved.
  • An issue where the <[Source Object Name]> label property would display point numbers instead of point names for projection labels on section views has been resolved.
  • An issue with the curb inlet calculation in sag in Hydraflow Storm Sewers and Hydraflow Express has been resolved.

 

Remove Layout1 and Layout2 tabs in AutoCAD

This is a great write up on how to get rid of those pesky layout tabs. Thanks Sam!

CADproTips

Do you every get annoyed by those default layout tabs in AutoCAD?  Why are they there? Can I remove them? I always instruct my users to rename the layout tabs (right-click-rename) to an appropriate name and/or remove if they are not used.  Here is a trick on how to remove those tabs using a macro placed on a tool palette.

The default setting in AutoCAD will display a Model Space Tab along with a Layout1 (1) and Layout2 (2) tabs as shown in the image below. The Model tab represents model space which is where you draft and design the model of your project. The Layout tab represents the paper space environment where you create layouts typically including title blocks, general notes, and a window of items drawn in model space.

01-layouts

First of all, you cannot delete the Model Tab; that is default by AutoCAD and used to create your model or geometry…
