Archicad broken 3D models and shaky 2d view

[Eetu S]

Hello, 

I have problem with broken .pln project.

The lines of the objects are not correct in 3d and 2d zoom also "shakes" when used. In 2d lines and points are in correct.

Attached is a picture of the problem.

Is the project far from the project origin? Graphic distortions are common if you draw in real coordinates and at the same time have objects close to the project origin.
