I "accidently" solved it by clicking zoom all extents before your reply, but in the link you send i found this.
Another situation that can cause clipping is when the Perspective camera mode is turned off. In that case, click the "Zoom Extents" button (it looks like a magnifying glass with four red arrows pointing outward). The camera zooms out to display the entire model, and the clipping is eliminated.
So you are totally right! Thanks a lot π
