Question: Is this a bug in geom3d?

Maple does not cope with the following simple example:


point(A,0,0,0), point(B,1,0,0), point(C,2,0,0), point(E,2,1,0):


           Error, (in geom3d:-plane) the points may not be AreCollinear


Should we interpret this behavior as a bug? I think I met with this yet 10-12 years ago, but unfortunately since then nothing has changed.

Please Wait...
