I then use walls with different fill. <BR /><BR />Till here all normal.<BR /><BR />Lets make 2 walls perpendicular. One normal and one with concrete fill used as a column. I make both walls 1m long and 20cm thick and 3m height<BR /><BR />Now go to the IS (interactive schedule maker)<BR />Make a wall list. The external surface on the reference (external) line = 1x3=3 square meters. BOTH. The 20cm overlap is not substracted by neither.<BR /><BR />I next change the layer of the column wall to a layer with a layer priority number ( i hope its called that way) 2. Now the column wall is on top of the normal wall but in the IS i still get 3 s.m for both.<BR /><BR />In the preferences i can set the priority for walls and columns and beams<BR />but for 2 walls i cannot do that.<BR />All computations are wrong. The volume of the 2 walls is wrong. The surface ...<BR /><BR />Does anyone know a solution to that problem? or am i somewhere wrong?</DIV> Mon, 10 Feb 2025 15:08:28 GMT Anonymous 2025-02-10T15:08:28Z https://community.graphisoft.com/t5/Documentation/Calculation-IS-Walls-and-Columns/m-p/99458#M16032 <DIV class="actalk-migrated-content">Usually i have to deal with iregullar column shapes.
