- Level offest can now be negative
- Auto wall grouping is now off by default
- Shape2DView (BIM version) now sets InPlace to False
- The Axis tool starts with only one axis by default
- Sketches initiated with the BIM Sketch command take Draft colors
- Snapping WP shortcuts were changed to avoid conflicts
