https://community.graphisoft.com/t5/Documentation/Contour-Lines-in-sections-do-not-comply-Building-Materials/m-p/238506#M36237 Hi,<BR /> <BR /> It would be hard to tell what it is exactly based on just this, but I think either the pens of the beam are messed up, or something is stuck in your project from the old version. Can you send me the file (in a Private Message) so that I can take a look?<BR /> <BR /> Regards, Thu, 06 Sep 2018 09:29:55 GMT Daniel Kovacs 2018-09-06T09:29:55Z https://community.graphisoft.com/t5/Documentation/Contour-Lines-in-sections-do-not-comply-Building-Materials/m-p/238505#M36236 <DIV class="actalk-migrated-content"><T>The images below show a detail of a section with a slab, a beam and two walls.<BR /> <BR /> The first image is what I get.<BR /> <BR /> The second image is what I want: I manually added vertical black lines on the edges of the beam.<BR /> <BR /> The reddish lines in the walls is masonry (priority = 510); the black lines in slab and beam is structural concrete (priority = 760).<BR /> <BR /> The priorities work as expected for the fills of the elements – concrete fill goes on top of the masonry fill, but not for the contour lines of the elements: the sides of the beam are red instead of black.<BR /> Changing display order does not change this situation.<BR /> All the layers have the same intersection index.<BR /> This project was started in an old ArchiCAD version (v7, if I correctly recall). If I set Preferences to use Legacy method for intersections, the problem with lines goes away, but then a bunch of other intersection problems arise.<BR /> Any tips?</T></DIV> Tue, 30 May 2023 07:58:46 GMT https://community.graphisoft.com/t5/Documentation/Contour-Lines-in-sections-do-not-comply-Building-Materials/m-p/238505#M36236 Durval 2023-05-30T07:58:46Z https://community.graphisoft.com/t5/Documentation/Contour-Lines-in-sections-do-not-comply-Building-Materials/m-p/238506#M36237 Hi,<BR /> <BR /> It would be hard to tell what it is exactly based on just this, but I think either the pens of the beam are messed up, or something is stuck in your project from the old version.
