HELP!

Three weeks ago I installed Condoc System, followed the tutorials and started working with it . I got really nice elevation drawings, but  plan views were a problem, see my earlier posts. Deleting some old scenes first seemed to help, but now not anymore. Section drawings in the meantime have become more difficult too. Today I reinstalled the extension, but that made no difference.
It looks  as if my project develops  something like an ‘allergic’  reaction to the Condoc System. Of course I don’t believe in such human behaviour, but what could be the cause? It must be something in the model guess, though it is well organised.  I have saved different stages of the modeling process, and all have the same problem with Condoc Lt.
