I tried to assign the properties to the structure, however in the BTU column there is an error sign and does not accept any changes.<BR /> <BR /> Thanks in advance.<BR /> Ara Thu, 08 Oct 2009 02:46:09 GMT https://community.graphisoft.com/t5/Collaboration-with-other/Please-help-with-ECO-design/m-p/164001#M18722 Anonymous 2009-10-08T02:46:09Z
