That thing has been blowing my mind for two weeks.I would like to subtract one body from another. One is pipe with curved section and second is blue surf thickening. That blue surf is made out of two curved sections and two tangent curves. The program successfully created, blue surf, than thickening to blue surf, But when accept subtraction it fails-"boolean operation failed". I attach images of that.There are two mentioned bodies. You can notice that in pathfinder subtraction failed.
However, when applying one tangent curve to blue surf instead of two, there is no subtraction failure. Maybe previous entered goemetry is two complicated to compute? But my geometry has typical aerodynamical design and program should be able to handle with that.
