Hello, if anyone is interested in trying the v21 beta please find it here: Build 21021: https://www.alibre.com/AlibreDownloads/AlibreDesignV21_setup_x64_188.8.131.5221.exe License Key: alibre-v21-beta Important Install Instructions: If you are installing the beta on the same machine as your regular license, you must first release the license via Home Window > Utilities > Release License prior to uninstalling your current version and installing the beta. Now, after installing the beta, you can enter the new beta license key. Please keep a record of your regular license key as you will eventually need it when you stop using the beta. As usual, do not save your production work files in this beta unless they are backed up. Saves made in pre-release versions may not be usable when the actual version ships. Notes: The Help system is not updated yet (as of March 3). We would like you to play with assembly constraints and let us know your feedback. Some textured cosmetic thread issues exist in this build, but should generally be stable. See all the things you can play with on the v21 feature page. Release Considerations: Textured Cosmetic Threads is still an implementation in progress. We've seen some significant performance issues in large assemblies that are not acceptable and will decide in the next days whether assembly-level thread display will be available in v21 or later in v22 after further optimization occurs.
