I would like to propose a slightly modified meta command set for the rotation points, based on the idea of Marc Klein. He suggested: 0 ROTATION CENTER x y z 0 ROTATION AXIS x1 y1 z1 x2 y2 z2 In MLCad I would like to use: 0 ROTATION CENTER "Name" x y (...) (24 years ago, 25-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)

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 (...) (24 years ago, 28-Aug-00, to lugnet.cad)
