hey guys,
I have little problem. I'm trying to draw ventilation in 3D ,and I have reached a point where two air ducts with different sizes must connect to each other,so basically I need to draw a reduction from 1000/200mm to 700/300mm. I tryed to draw it manually via lines and then to make a block of it, and it's working ,but when I use the HIDE command I still can see trough it. Any ideas?
