However I have beams in the opposite direction and the first two beams are in pieces now. How can I correct this? I tried with SEO operations but I got the same result. The invisible parts of the cropped elements still interacts with the elements above them.</T></DIV> Tue, 23 May 2023 12:13:44 GMT Anonymous 2023-05-23T12:13:44Z https://community.graphisoft.com/t5/Modeling/Crop-to-roof-question/m-p/271121#M141252 <DIV class="actalk-migrated-content"><T>Hello!

In that case the Beam will cut the other element.
