Dear Klaus,
Thank you very much for your question!
As Laszlo mentioned, we will need more information to be able to identify where the problem is. As far as I know, the markers are usually exported as blocks along with windows/doors, maybe this is where the problem is?
I recommend trying the following option: under
Save option
of the given DWG translator, please set
Explode complex ARCHICAD Elements
for
Saving Floor Plan
section.
Looking forward to hearing from you!
Best regards,
Minh
