Create my own 2D symbol furniture set

[Keet]

Unfortunately I don't understand what to do. Here are both 2D symbols, can you prepare them properly for SH3D so that they appear as windows and doors in the 2D view? Thank you very much.

In previous posts in this thread you managed to create 2D symbols. What you probably are trying to do is to make a 2D symbol snap into a wall like a window. That is not possible. You have to resize your 2D symbol in the 2D view and move it over the actual window.
If you only use the 2D plan for printing you can omit the window and only use the 2D symbol to represent the window. Just resize it and move it to the place on the wall where you want. Move it fully zoomed in with the keyboard arrows.

I always edit the image in Illustrator and this is how I wanted to speed up the process. If it really doesn't work, I'll stick with adding windows and doors in Illustrator.
