Maybe I did not explained well.
What you suggest dear seirov allows only to change view (lateral, upper/lower, frontal/real). It does not affect the perspective projection into ortographic projection of the view.
I want to remove the perspective projection (that create distorsion on the bodies) and I want to use ortographic projection (that allows NO distorsion of bodies).
In attachment an example of the two bottons that I am looking for, that already exist in MESH and PARAVIS environment (but as said, I can't find it into the post processor of Aster Study).
