I am now at the point, racking my brain, searching the net, and I can't seem to find any good info or tutorials on intersecting two meshes, and then add or subtract them, like I can with Unreal ED, and I do realise that Blender doesn't do CSG, but surely there must be another way of doing it.
For example, I want to make a hollow tube, Idraw a circle, and extrude it, I draw a smaller circle over lapping the front face and extrude that, but it doesn't let me subtract (difference) the smaller cylinder from the larger cylinder to give me a tube.
In the above example how would I subtract the smaller from the larger?
