Hi,

Trying to make a round indent. What am I making wrong so the object is hollowed instead having a solid body with a ball indent?

Did you opt to leave original bodies? If so select the object and delete and the indent will be there? Maybe? 🥴

It might have been a tessellation problem, export / import fixes that, so could reopening the design.
