This beta version is specifically available to owners of a v4 license key . How to Access and Download Official Beta Page: Qualified users can download the software from the MoI 3D Beta Portal .

You can now delete objects/groups without selecting them first or transfer them between groups within the browser. Advanced Polyline Input: The point picker now supports relative angle values using polar coordinates (e.g., 5r45 or 9L20 ). You can use "L" or "R" for left/right and case sensitivity to distinguish between inside and outside angles. Bug Fixes: Recent updates have addressed Mac-specific bugs like double-click loops during file dialogs, as well as crashes during complex Extrude operations and boolean union errors. ACIS Filleting: The beta includes ongoing improvements and fixes for ACIS filleting, though some users still report specific cases where the older Solid++ engine performs better.
