What's New in AutoCAD Mechanical 2025 Toolset

Learn about new features in this release of AutoCAD Mechanical 2025 toolset. For technical details, see the release notes.

2025.0.2 Highlights

Change from .NET 8.0 and 10.0: Microsoft will stop providing updates for .NET 8.0 after November 10, 2026. For this reason, Autodesk and other software developers are encouraged to transition to .NET 10.0. Custom applications targeting .NET 8.0 should continue to function, except in cases where changes or removals in .NET 10.0 introduce compatibility issues.

Important: Due to potential compatibility issues introduced by .NET 10.0 in the AutoCAD Mechanical 2025.0.2 Update, the corresponding AutoCAD 2025.1.4 Update must also be installed. If other AutoCAD 2025-based products are installed on the workstation, such as Autodesk Civil 3D, the AutoCAD Electrical toolset, or Autodesk Advanced Steel, you must install the latest available updates for those products to maintain cross-product compatibility.

2025 Highlights

Standard Revision Updates Surface Texture Symbols

The surface texture symbol now supports the latest revisions of ISO (ISO 21920-1:2021(E)) and ANSI/ASME (ASME Y14.36 - 2018) standards.

Enhanced Content Library Parts

New mechanical standard parts have been added to its content library in multiple languages.

Activity Insights

Activity Insights has been further improved to provide more detailed information about drafting standards and symbol revisions.

Quality improvements

Mechanical Standards: Mechanical standards are now preserved when saving a drawing to a previous release format.

Viewports: Dimensions for chamfer now respect scaling when the viewport is created using the -VPORTS command.

Hole: Optimized preview experience for creating block with hole feature.

Hole Chart

• Performing an undo in the middle of the AMOFFSET command no longer affects object snap settings.
• The hole chart feature now has the capability to display the degree symbol for polar coordinates.

Centerhole: The AMCENCRHOLE command now provides more accurate hole placement.

Structure: The side view of a shaft component is now generated accurately in mechanical structure.

Construction Line: Consistent precision is now ensured with construction line commands, eliminating occasional object omissions when drawing in a zoomed-out view.

AdMigrator: Enhanced accuracy when migrating from a previous version of AutoCAD Mechanical .

Taper Symbol: The Insert Symbol textbox now has the capability to seamlessly parse GDT font.

MarkupAssist: Enhanced stability when switching modes from TRACEFRONT to TRACEBACK.

Content: Enhanced precision in evaluation of nested parts and features like keyways.

Additional enhancements

2D Graphics:

• Font display improvements.
• The Graphics Performance dialog box includes a new "Diagnosis" tab specifically designed to diagnose common graphics card issues.

3D Graphics: The Wireframe visual style has been added to the cross platform 3D graphics system. See the Fast shaded mode option in the Graphics Performance dialog box for more information.

File Open Performance: Improvements have been made to reduce the amount of time it takes to open 2D drawing files.

New and Changed File Formats: The ACTM and DXE file formats have been replaced by the new ACTMX and DXEX file formats.

• ACTM files must be migrated to the ACTMX file format before they can be played back. New action macros recorded are stored in the ACTMX file format and are not compatible with AutoCAD 2024 and earlier releases.
• DXE files can continue to be used to extract data from a drawing, but changes can't be saved back these files. Changes can only be saved to the new DXEX file format which is not compatible with AutoCAD 2024 and earlier releases.
