There are settings for beam-wall intersection behavior, but the easiest is to have the layer intersection priority number for your beam layer be different (higher/lower does not matter - only being different matters) than the layer intersection priority number for your wall layer. Then, the beams will not pre-subtract themselves from the walls and your SEO will work fine.<BR /> <BR /> Cheers,<BR /> Karl Sun, 06 Feb 2011 16:32:56 GMT https://community.graphisoft.com/t5/Modeling/Problem-with-SEO/m-p/170286#M92184 Karl Ottenstein 2011-02-06T16:32:56Z https://community.graphisoft.com/t5/Modeling/Problem-with-SEO/m-p/170287#M92185 Spot on Karl,<BR /> Thank you for the time taken to reply, it is much appreciated...<BR /> <BR /> Al Mon, 07 Feb 2011 08:20:26 GMT https://community.graphisoft.com/t5/Modeling/Problem-with-SEO/m-p/170287#M92185 Anonymous 2011-02-07T08:20:26Z
