Ist there a way to know if
Brep.CreateBooleanDifference did actually subtract anything from the input brep?
Lets say the brep and the trimmer are just touching each other.
Even if the returned brep is the same as the input , calling
Object.ReferenceEquals returns always false.
Would I first have to compute
CreateBooleanIntersection and see if it returns anything ?
Since these calls can be expensive I would like to avoid that.
