I am trying to use Shear to shear a polysurface. I used points to shear the polysurface so the top edge moves in 1mm increments.
- Select polysurface.
- Shear
- Select 0,0,0 as shear origin
- Select first point
- Select 1mm, 2mm or 3mm point to shear object.
The first attempt worked perfectly and I added a 1mm shear to the top edge. When I tried to do the same thing to create a 2mm and 3mm shear it tries to create a much bigger shear and seems to snap to a minimum angle either direction…
I cannot work out if I have done something to cause this behaviour or if it is a bug.
I cannot recreate the 1mm shear.
Can anyone see what I am doing wrong or if this is a bug?
Attached is the rhino file with the original and the successful 1mm shear.

EDIT: Answered my own question… I was snapping to the end of the top edge of the polysurface for the first reference point instead of point0. This was actually (0,0,-22) which was causing the weird snapping behaviour.
