I feel your pain. Just spent 3 days trying to solve a problem. 6 Storey model is now corrupt to the point I may have to redraw it but it'll probably end up with the same issues.
I've never had such issues with other software. Its a constant battle.
Which version are you using?
Hi John, sorry to hear that you are that frustrated, please can you give us some details of the problems you are encountering?
Regards
Marc
