I have a problem. I want to create the negative of a part, meaning the air volume as a solid (as preparation for a CFD simulation).
Here is what I did: I created a box around the part and tried to subtract the part from the box using the Cut command. But I cannot select the part and I don’t manage to make it work.
Hello,
What module are you using for your geometry, shaper or geom ? Can you send us more details ?
You should indeed use the cut operation but if you cannot select a part I assume you are using Shaper. You need to have both objects defined as “results” in the shaper pannel.
Best,
Louis
If your geometry consists of surfaces, you can group them into a closed shell and then convert it into a solid.
Otherwise, you can use the Boolean function to remove the solid part from the domain to create a fluid region.
