Hi,
your last AECOsim Questions were posted in the German Building Forum. Please bookmark this link:
http://communities.bentley.com/products/building/building_analysis___design/f/5917#pi20290=1
for the English Building Forum.
You will save time and will get a faster response, because you don't have to wait till the Germans start working in their Morning to move the posts.
All the best for your work with Bentley Products,
Regards S. Janku
