Recently while trying out Shapr3D on Mac, I noticed that undo and redo just don’t seem to work at all. I used an extrusion to subtract from a body I was editing, and then realized the subtraction wasn’t how I wanted it, but Cmd-Z does nothing, and the “Undo” menu option in the edit menu is grayed out. Does the app not support undo, or am I missing something?
EDIT: After restarting the app, Undo/Redo behavior started working again for a while. At a certain point, I attempted to enter a dimension while using a tool and pressing Enter would result in the Mac error chime. After this, Undo/Redo stopped working, and the menu items remain grayed out. It appears the app enters a specific state where it stops working and won’t start working again until backing out of modeling and then entering again.
