I've attached a picture of a wall roof joint, where I would like the concrete core of the roof to meet the concrete core of the wall. I know I could do this view-specifically by "Cut Profile" tool. However, my question is: Is there any way to do this in actual 3D? So that the joint would look the same also in other sections?
Thanks for your answer! It's great to know about the "Parts" tool, because I can use that, if "Join Geometry" doesn't work. I did try the "Join Geometry" tool before posting my question, but it seems like a window interferes with the joint, so that it doesn't do it right, if the window is not situated higher than the roof slab. In the file attached, the joint on the left side is correct, but the ones on the left are incorrect.
