Take a look below.


first draw a line longer than you need so you have overcut of the part, then draw a semi circle like the one in red in your software look for extrude, pick the line as your length of cut, then pick the semi C as your profile and merge them together, you need to orientate your part or the drawing to cross your part using the top face of the part as the XYZ =0 you end up with a semi circle cut into the part as shown.
Hope it helps, if not give me the exact sizes of the part you want to cross and the size of the semi circle and I will do you a code to cut.

ah that's probably why. I don't have "extrude" in my CAD software. What software are you running for example ?
looks like vectric

Take a look at the 4th paragraph down Extrude.

I wanted to mill a simple semi circle slot along the horizontal plain of the material. The circular slot is to be 120mm long / 11.113mm deep

Dudz, did you get this sorted ? there's a thread here just like your issue; http://www.cambam.co.uk/forum/index....31125#msg31125
