I'm wondering what is the purpose of RPoint in elbow parts. It is listed as optional point when you check your part with Library Component Wizard. I found in some earlier topics on this forum that it is necessary to have it if you want to drag & drop the part in the route. I do not have RPoints on my elbows, but i am able to drag & drop it. Is this one of those old settings which were required in older versions of SW and is still present, for some reason?
