I am working on an arch for casing on a half round window. After completing the finishing pass I want to clean up the shoulder pointed to in the attachment. I tried using the vector that was used for the finishing tool path. I selected the vector, the profile toolpath - outside and offset by .01, that didn't work, I tried offset by .02, .03, .04. The offset didn't move the tool closer to the edge of the shoulder, it didn't move it away either.
I'm looking for a way to clean of the edge of the shoulder- suggestion?
