@alok Hello bro, Thank you very much for your help, I did it just like the images but it doesn't work for me to draw the bos and choch, I have tried it just as you propose but it only draws supports, I also tried many ways that I found on the internet but so far no I managed to get it to work to draw the bos and choch, if you or someone else in this forum has managed to draw the bos and choch, I ask you to please share a thread of your project or idea where the bos and choch are drawn... please?
Here I leave the thread of what I did following your idea...
