Subtracting solid from solid
 

Hi guys;
I'm using Design modeler for CFD analysis for a nose model of a formula student car.
I used Boolean> subtract >
target body> air volume "fluid"
tool body> Car CAD "solid"

but this error appears.

Thanks.

Its not possible to sutract a surface body from a solid body. You need to create a solid from your surfaces. Check out the Sew commant in "body operation" in order to do this
