The following is an overview of the changes made to AutoCAD Mechanical 2021 toolset.
AutoCAD Mechanical 2021 toolset 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. The drawing format for this release has been upgraded to AutoCAD Mechanical 2021. For developers, this is an API-breaking release.
The welding symbol has been updated in AutoCAD Mechanical 2021 toolset to support the latest ISO and DIN standard revisions (ISO 2553:2013 and DIN EN ISO 2553:2014). The changes include the revision of the elementary and supplementary symbols, and the new weld notation (Distance between two points). The multi-reference line support is also added to the latest revision.
With the added support to the new ISO and DIN standard revisions, you can annotate documents created in AutoCAD Mechanical toolset using the latest revisions of the welding standards. Although, you can use the latest revisions in new documents, AutoCAD Mechanical toolset will continue to support the legacy revisions to allow documents created in previous releases to be opened, edited, and saved.
Layergroups can now be created with names containing special characters such as ()[]{}#$%&+@^.
Working with automatic dimensions no longer causes an error.
The simple weld can now be edited correctly using AMPOWEREDIT.
Content can now be edited using the family table without causing an error.
The FIELDEVAL system variable does not voluntarily change its value after publish operation.
Changes to the dynamic blocks are immediately reflected in the drawing.
The text height of a leader note now displays the correct value when the border scale is more than 1:10.
Working with the PDF Import dialog box options no longer displays an error.
Limits and fits for M3 tolerance now display the correct values.
The surface texture symbol now stays associated when a drawing is re-opened after saving to older file format.
AutoCAD Mechanical toolset leverages most of the new features from AutoCAD. For more information, refer to the What's New in AutoCAD 2021 topic in Help.
