Hi James,
Ok that’s good will stipulate the 4 edge requirement in my other post.
However the concern I have is once a surface that does not meet that
requirement causes the macro to crash and the following correct
surfaces also crash.It would be good if a reset within the nod was possible.
The only way I see to reset the nod file is to close and reopen Moi ?
Anyway thanks for your help I think your macro is well worth developing.
Only wish I had the knowledge to be more help.
Barry
