Issue with circular pattern extrusions



I’m having an issue with performing circular extrusions. I start with a section view and make my through hole. I then select the hole and rotate and it makes the extruded holes without issue. I then make my second cutout, this time, I extrude up to knock it out of the dome. Then I try my pattern and it conflicts and won’t perform. I’m not sure if it’s the way I extruded the second cutout? Has anyone seen this? If so, is there a better way I should be creating the pattern?

On a side note, I can easily make a pattern of the knockout as a solid object, make the pattern, selected body 1 and subtract the circular pattern from it. I guess my real question is, why is it conflicting when attempting to do it the way I show in the video.

I believe the logic is you are staking booleans on booleans.

On your video booleans works on areas that doesn’t already have booleans.
