Allows for the recording of commands to automate repetitive tasks.
Once a drawing saved to the cloud is opened in AutoCAD 2021, a dedicated palette appears. This palette lists all previous versions of the file, filtering them by date, user, or time increment. With one click, the user can launch the DWG Compare tool to see exactly what changed between versions—new objects highlighted in green, deleted in red. This capability allows teams to import changes from a past version directly into the current file, effectively creating a non-destructive, visual version control system within the CAD environment.
The 2D graphics engine was completely rewritten for this release. It automatically recognizes specialized graphics hardware to optimize data rendering. This optimization reduced the time spent waiting for drawing regenerations ( REGEN ) when toggling layouts or switching between model space and paper space. 2.
