In Sketchup, if have a shape that I want to cut a section out of, I can use the pencil tool to draw an area and then extrude the area down (using the push / pull tool). The outside edges are removed:
In Blender, I'm trying to do the same thing but it isn't working in the same way. I used the Knife tool to draw the area I want to remove and extrude down, but the outer edges are still remaining:
I haven't yet figured out a way to manipulate the mesh to get the desired result after this extrusion.
Is there a faster / better way to do this in Blender? Is there a tool that behaves similarly to Sketchup's push / pull tool?
