Split primitive in two I am trying to split a cylinder in two parts with a plane being the cutting object but for some reason it doesn't work. Intersect works, and applying Difference on the plane works too but applying Difference on the cylinder to end up with half a cylinder doesn't do anything. I tried flipping normals and Moving the cutting plane in Z just in case it sat on cylinder vertices but it just doesnt work. Any idea why ?
One way is to use the split and vertex
connect operators.

First step would be to use vertex
connect
and create two faces of the ends of the cylinder by selecting two
adjacent vertices and pressing J
Then Simply select either the top or bottom half, and press the
Y key to split.
