I’m designing some compartments, and I’m facing a slight issue. For example, I have a model with some edges that have different curved profiles. Now, I want to extrude it into a compartment, but how can I make it a rounded compartment that follows the profiles of the remaining outer edges? In the image, I could only extrude it up to near the bottom of the compartment. Thank you.

Hi,

Make the boxes first, then use the shell tool, you can select several faces 👍🏻

Or use the tool directly on inner bottom surface, take away the fillets first.
