Some quick notes:

Shift while drawing now works for an enhanced straight snap. When you hold down shift straight snap will have priority over object snap, and the current straight snap line will stay locked on for as long as you hold shift. Also when you hold down shift straight snap will activate to the closest straight snap line regardless of how far away it is to the mouse.

AI format for clipboard transfer should work on on OSX.

Some bugs fixed in surface/surface intersection, some cases that didn't work before with things like 2 pipes crossing each other should work better now.

Layers are exported to DXF format

Bug fixes to Blend between 2 edges that touch each other at sharp "pole points", and to order sorting for loft to point.
