I have an aluminum block that I am running 2 stainless steel coil tubes through. I want to subtract the space occupied by the coil tubes from the Aluminum block. Can anyone help? I have used the intersect command before but I can't get it to work in this case and I am not sure why. I tried joining the coils to the Aluminum block part which seemed to work. However, the Aluminum block is cannot be selected as a separate body as the coils in the intersect command.
Included is the assembly that has the 3 parts.
