Is it possible to rotate the cgboxes in OPS?
Or align them basically to their corresponding part?` Right now I just have your basic right angle boxes, but say when I look at the p38 in OPS I see the cg boxes following the contour of the part. Instead of a square I see a rombus-alles klar?

Hi wil,

Here is some info on inertia boxes:

I don't think OPS renders inertia shapes, just a green bounding box. Bryan?

Well it seems to at least apoximate the cylinder inertia shape... see the pic above. You can set the shape in the property list for that inertia box.

Intertia (BG) volumes can't be rotated. The ones you are looking at have the actual part rotated and the Inertia box is relative to it.

OPS draws the right shape for boxes, cones and cylinders, spherical volumes are represented by a box, suppose I should do a real sphere one day...

Meshes are always an approximation
