Subtraction tool

Hi everyone,

I want to cut a groove into the inside of a half pipe by using the subtraction tool. First I create the half pipe, then place a thin disk over it. In the next step I position the disk at the right height and want to subtract it from the pipe to create the groove. Unfortunately after finishing the subtraction process there still is the combined pipe and disk.

Any ideas?

Thank you very much.

It seems you set the tool to keep the original bodies, if you change them to “none” or the specific one you want to keep, it should do the job.
