I'm writing here instead of writing under an old staircase There are definitely renovation works on the staircase drawing, but to talk about the current version; I'm really bored with a lot of nested, unrelated blocks. It's a lot of work in 2d edit. I also run into a lot of other problems when I blow up all the blocks. Please quickly change the blocking logic on the ladder in a short amount of time. Even the drawing of stairs comes together in blocks. Also, I may have written similar things before. It would be much nicer if we could draw the staircase together with the axis, column and beam around it. ....There was a command in the CAD program. You select a rectangle. It takes inside, all the rest is trimmed and erased. With such a method, the section selected from the formwork plan with a rectangle can be the plan of the stair detail. Also, in the stair formwork plan drawings in 3d (with its name). m1-m2 etc.) should be drawn together. I have no doubt that you are doing a study on these, but I still felt the need to write with the thought that it could create an idea. Take it easy.
