Rote prim around one edge

The answer to this newbie question has escaped me. How do you rotate an object (prim) around one edge. For example a door has a vertical hinge so how do you rotate the door prim around it?

Either attach a prim that has its center at that edge, and use that prim as a hinge (put the rotate script in it), or path-cut the prim so its center is on the edge. You can create a "hinge" edge of a rectangular door by quartering the prim with path cut.

heyas;

if you cant possibly cut it or parent it to something (flexi-wings, for example), you can look up my RotFromEdge function, posted around here on the forums.

Thanks for the info but from what I read there are still problems you are working on so I'd rather stay away from developing code based on untried scripts. No offence intended but I don't have time to debug your code as well as mine.
Thanks for the thought anyway.
PS The suggested solutions worked fine I just have to refine the shape of the cut block object.

actually RotFromEdge() is done and works fine. as long as you use the latest (bottom) one. the RotFromEdge3.... is still wonky, but a different function, really.


i suppose i should put the final RotFromEdge in the actual library....
