Each year, Autodesk releases its new version of products, including AutoCAD 2021. As in previous updates, AutoCAD is updated with new commands, and even some changes to the existing commands have occurred. The ARRAY command change in 2013 and the new Layers command before that are just a couple of notable examples of past changes.
I have always liked the Trim and Extend commands in Autodesk Inventor, and now AutoCAD 2021 incorporates the same simplified behavior. As you might remember in previous versions, when using the Extend or Trim command in AutoCAD, you were always prompted to select the boundaries first. Now in 2021, AutoCAD detects the boundary(s) automatically, saving the step of having to choose one or more items before selecting the actual items to Trim/Extend. Another nice change, is that the command default to a fence selection, making it ideal for selecting groups of objects.
Have you encountered the “Invalid Serial Number” message? We frequently see support cases opened for this issue. It usually appears when customers upgrade or switch to subscription and need to install a new product. Autodesk products are typically activated by entering the serial number and product key. However, doing this now may cause the following error and stop you from completing the process.
