[cgma-dev] subtract with OCC

[Leidy Suarez]

We have a question about the method:
 "subtract(DLIList<BodySM*> &tool_body_list,
           DLIList<BodySM*> &from_bodies,
           DLIList<BodySM*> &new_bodies,
           bool imprint,
           bool keep_old) const"
in OCCModifyEngine.

When we make the boolean operation of subtract with the bool parameter 
"keep_old" setting to "false", why the bodies: "from_bodies" continue to 
exist?. Why did only the bodies: "tool_body_list" are eliminated?

Thanks,
Leidy
