I have a model pictured below that I am trying to create a channel for. This part was created using surfaces so I think using standard extrude/ revolve cuts will be out of the question. The sketch pictured here is what needs to be cut into the part at a uniform depth of .050". My goal is to first be able to produce this cut. Secondly I will be splitting this top part into (2) pieces to create a lip for the two pieces, similar to the lips created on the side of this part. Any ideas. Thanks in advance everyone.
