If I have a roof ans slab that goes threw lower vertical edge of this roof, and I preform operation substraction with downwards extrusion on roof using this slab, I got shape which I want. Roof edge is cut in the way that it has 90 degrees angle, vertical and horizontal parts, like end of rafters or trusses.<BR /> <BR /> Now when I make cross section threw this roof and slab I do not get this line which should by where slab and roof have common edge. If slab is off this line is there, but I need slab and the roof on section.<BR /> <BR /> Any thoughts?<BR /> <BR /> Cris</T></DIV> Tue, 23 May 2023 13:35:14 GMT Anonymous 2023-05-23T13:35:14Z https://community.graphisoft.com/t5/Modeling/why-some-lines-are-being-lost-in-cross-section-window/m-p/110768#M58466 <DIV class="actalk-migrated-content"><T>Hi, I have this problem with cross sections.<BR /> Lines that should be visible re somehow lost and I haven't find any way to get them visible.<BR /> This happens on some elements that are operators and target elements of solid operations.
