Sorry if these requests have been made already-- I haven’t seen them.
-3D Clipping mask: functions similar to clipping masks in illustrator. Essentially a non-destructive version of solid tools intersect
-Actions: similar to how you can record actions in illustrator or photoshop. The functionality would probably need to be limited to movement, rotation, and scaling for groups. This would be helpful for arraying objects in situations where they are rotating along two axes and moving.
-Axis Snap options: in addition to snapping to XYZ axes, it would be helpful to have the option to set intervals (10,15,30, 45) that you could also snap to.
If there’s a plugin for any of these, I’d appreciate the tip.
