Hi
Can i import images to my 3D plan (i'm not talking about the background image) ??
if the answer is yes, then how ? [:-/]

Thank you for your replay i appreciate that.
I found the solution to my problem. I was right in thinking that perhaps the source of my issue was the angle changing by 15° when I tried to draw the wall , and I believe this is called magnetism.

The solution for anyone facing the same problem as me ...

when i want to creat the walls folowwing the real mezures i have the end of the shape does not stick with the start (i can not change the angle°) , if i can change the grid steps and make it smaller this can fix my problem.
any help please [:((]
