I asked a question before about this subject but I think I was talking nonsense. Here it is if you want to see it: https://forum.solidworks.com/message/266189#266189
I think now I may be able to portray what I am aiming to acheive in more detail as I have found an image of exactly what I am aiming to do:
I want to make an cut (10mm radius) through bottom of the tagent arc (which is 11mm radius) in the shape of an arc. Can anyone help and I would like to know if this is easier to understand than the first post?!
