Automatic extraction doesn't work in this case - you literarily need to redraw all floor for each room.<BR /> Maybe it's easier to model skirting to get the right number.<BR /> Or.<BR /> You can use zones for room perimeters. Skirting length = Zone Net Perimeter - Doors Width. Just make new expression based property.

This way the walls section the screed. <BR /> <BR /> I would like to calculate the linear meters of intersection between the slab and the walls with a schedule. is it possible or is there any other way that does not imply to model de screeds in 3d? <BR /> <BR /> Tanks in advance</T></DIV> Wed, 07 Oct 2020 13:59:04 GMT https://community.graphisoft.com/t5/Collaboration-with-other/Screed-edge-calculation/m-p/286228#M37449 Anonymous 2020-10-07T13:59:04Z https://community.graphisoft.com/t5/Collaboration-with-other/Screed-edge-calculation/m-p/286229#M37450 If you need to calculate screed edge length - you need to model this edge.
