HI all!

I really need your help here.

I 've been trying to create Dummy zone for my DOAS system in Detailed Mode.

First, I create "Floor" then its child "Space" whose area is same as the
zone served by the DOAS. I used 'Box' method.

However, an error massage that says "Unable to locate default data for
Command=FLOOR,Type=0, Keyword=WIDTH" keeps popting up, followed by

"standard file writing errors. "

How can I fix this problem?

Thank you in advance!
