Atharv Joshi Thanks for looking. I am on API v23 inside spaceclaim R2023r1. Also have the same problem In R2022 R2 API v22.

I start the recording with selection set to index and verbose. I box select the bodies and hit interference volumes and the tool runs but nothing appears in the script. Then I create the interference volumes and still nothing appears. Changing those bodies to red colour in the next step, and that does appear in the script.
