What about passing axis points to larger models? Each submodel needs to be able to say: 0 use the rotational center of the following part: 1 15 0 50 -34 1 0 0 0 0 -1 0 1 0 part.DAT Then inheritance (not really "inheritance", but whatever) would be as follows: 0 ROTATION (keyword for inheritance) CENTER nameOfNextPart nameToBeUsedInThisPart 0 ROTATION (keyword for inheritance) AXIS nameOfNextPart nameToBeUsedInThisPart for example: 0 ROTATION INHERIT CENTER hinge elbow 0 ROTATION INHERIT AXIS hinge elbow 1 15 0 50 -34 1 0 0 0 0 -1 0 1 0 partWithHinge.DAT Then the submodel will have a rotational point at the "hinge" that would be defined in partWithHinge. This submodel's rotation point will have the name "elbow", which can also be inherited if it is included in a larger model. James

(...) Hmmm, kinda clunky. What we need is some kind of namespace resolution for referring to lines from other parts. Cheers, - jsproat (24 years ago, 29-Aug-00, to lugnet.cad)

Ok more information: The modification flag is used to allow the user change the coordinates of the rotation point or not. E.G.: Rotation points of parts in the library must not be modified by the user, while in his own parts a user can do what (...) (24 years ago, 26-Aug-00, to lugnet.cad)
