Hi

is somebody familiar with this problem?
I create a new project from scratch.
I´m making new wall´s and when I open the animation window they look like 3D atari from 1981.

I know is not the computer. (before anyone suggest drivers)
I know is not Allplan either. (Second picture show a more complex drawing, made in the same computer last week)
My guess is properties problem (third picture) I check them with the walls that look good and have same parameters (just different heights and texture )

Is not the texture problem, each wall have different texture and one no texture at all (picture one) and they suffer from the same deformation.

As i rotate the animation view point they change shape.
