Hitting this wall while I continue to learn SolidWorks. I created a straight pipe from "Plane E" to the surface of "Plane A" instead of stopping at "Plane D" surface and then create another pipe from "Plane B" surface to "Plane A". Now I have the pipe in between "Plane B", "Plane C" and "Plane D" that needs to be deleted. Is there a better way to cut the pipes? Any suggestion?
