I spent all night trying to select this face for machining. it is just the first step in the machining process but I figured out that if I draw the part in the order it will be machined and hide later features it made it easier to select surfaces that would exist when they are to be machined.
this face I have done in cambam befor by drawing a box around it and doing a pocket. its just a .056 boss left, but I can't figure out how to explain that to MC4SW. if I select the chain on the face it only pockets inside or if I deselect machine as open have and machine closed chains regular- it does overhang the edges like I want but it does all 4.
it seems like I'm just not selecting the right item(s). I tried the vertical face, the intersection line (this was closest but still wrong), tried face milling just to get the part made but it kept going on the X which would cut off the face too. I tried the three edges which over hung the boss... so it seems easy, but out of reach
I think I could do this by adding stock to the end opposite the boss and selecting those two edges, but I'm thinking thats going through d,e&f to get from a to b.
