Simplify Command Enhancements (What's New in 2025)
Starting with this release, components can be replaced with a simple cylinder.
To do this, select any of the "Replace" options in the "Replace with Envelopes" area and set the type to "Oriented Minimum Bounding Cylinder". When the 'All In One Envelope' type option is selected, the Diameter and Height values are displayed both in the panel and on the canvas.
