I have moved it here to 'Working in Archicad' as it seems to be a typical modelling/drafting problem.
It is not a problem.
I just thought I would let you know so you get a notification and would be able to find the post if you go looking for it again.
If I just move it you might go looking in the Library/GDL section again and it won't be there.
Plus, now you know where to post if you have a similar issue.
