AC 21 is extremely slow in 3D.

1) It cuts elements very far from camera.
2) 3D cutting doesn't work, ac freezes every time I try to edit in 3D cut.
3) Sometimes everything is hidden in ac, but when I hit cmd+A, the selected elements' selection will be visible.

macOS 10.12, AC 21 4022, with GH connection (GH doesn't work either...)

The clipping issue could be caused by objects being very far from the project origin. Try using the Marquee tool around the main portion of the project and seeing if that fixes the clipping issue.
