Thanks to you I discovered i was not working with the latests NED version, I upgraded from 3003 to 4006 and at the moment it seems to solve my issue ! Thanks !
Having the same problem here, Archicad 23, so far can't fix with with layer setting etc'.
What does the information panel say?
even more than that a lot of times AC23 just crashes when trying to edit those zones. We are second half of the year and this is still an issue.
Have you sent off the bug report?
Keep a copy of the bug number and contact your local support quoting that number and ask them if they have any idea what was causing the crash.
Also are you running the latest update?
