Here is a STEP file, I imported into HeeksCNC.  I need the geometry in the XY plane. So I transformed the top face to the XY plane, by right clicking on the top face and choosing "Rotate to Face".  I can then extract the sketch by right clicking on the top face and choosing "Make Sketch from Face".  The sketch has both loops in, so I need to right click on the sketch and choose "Split Sketch" to make it into two sketches.  I can then use these sketches to make pocket and profile operations.  |
