Like many, I installed sketchup with wine, and when I run it, everything appears except the central image (the workspace);
Then I looked at the ubuntu doc page, I read the forums on the issue.
Commonly proposed solution does not fix the problem.
So I asked if we should not install NET.framework indispensable under windows.
So the question is: for whom sketchup displays without problem have they previously installed Net.framework 2?
