It has to be a setting elsewhere, but I've gone over all that seem pertinent to no avail...I wish in the future we had a clean interface with less clicks and more centralized commands....

As you can see, room xx is 243" perimeter x 11 feet high= 222.75sf. However the schedule generates a 149.62 sf value. Any ideas why or how to get an accurate number?<BR /> Generated on AC15 v3602<BR /> Thanks,</T></DIV><BR /><IMG src="http://community.graphisoft.com/t5/image/serverpage/image-id/73429iDBC8E282CC023C6D/image-size/large?v=v2&amp;px=999" border="0" alt="ac15.jpg" title="ac15.jpg" /> Wed, 06 Jun 2012 21:19:18 GMT https://community.graphisoft.com/t5/Collaboration-with-other/Schedules-Wall-Surface-Calculation-error/m-p/156824#M17741 Eduardo Bell 2012-06-06T21:19:18Z https://community.graphisoft.com/t5/Collaboration-with-other/Schedules-Wall-Surface-Calculation-error/m-p/156825#M17742 Missing file attachment.
