Given a drawing of a pulley profile:
One would start by duplicating in place and then Node Editing:
right-clicking:
“Cut Vector”
Then grab the cut node and drag to a grid intersection:
Go into Node editing again:
and drag the nodes away:
and then attach lines to them:
Done
Done
Done
Select and join everything:
Then go into Node Edit again:
Select the lines/nodes:
and restore the circle:
Then restore the position:
(note that this should have been done with a suitably larger circle)
Then assign a full-depth No Offset Contour toolpath with a keyhole tool after clearing the surrounding material and entry area with a pocket cut.
