Yeah, in that file I sent I remove a lot of stuff I guess now it can be done. I have the same issue with other elements in the project. I tried switching order but it is just random sometimes it works, and sometimes it doesn't work. I'm doing a house made up of concrete masonry walls, concrete columns, and beams. Both beams and columns are flushed in the walls, with the exact same thickness.
For the presentation ( Elevations, sections, and 3D) I want the joins of all the 3 categories invisible because in reality there are not going to be visible, so I have to go full AutoCAD on the linework and make the lines invisible. By doing so I cannot edit the building because if I modify or remove or add another element, the linework is removed so I have to go back and make them invisible.
For a possible data analysis and construction purposes, I want the columns and beams to have the real measurements, which will be subtracted from the measurements and volumes from the wall.
But apparently, even by joining and switching order, there are some join lines that stay there. So, my question will be, what else is on that chapter to review besides the 3 options of join geometry (join, unjoin, and switch order). I also get the error: One element is completely inside another, when joining the beam to the wall and thus the beam is not reporting a volume, also some columns change the height while joining and others just stay with their normal height with the joins invisible. The join changes the column height and removes the volume of the beam
In the meanwhile, I had to add an unnecessary 1mm finish layer to each side wall’s core in order to hide those lines. It can be less than 1mm because those lines will keep appearing
Also, I followed the steps https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/sfdcarticles/sfdcarticles/D... .
