#### Bug in geom3d-package in Maple V.5 (15.3.99)

##### Arnold Zitterbart

Bug in the geom3d-package ! intersection(s,p1,p2) fails, if s is parallet to x1_x2_plane

g is obviously parallel to the x1_x2_plane

but s is not the intersection-line:

The sign of the x3-coord has to be changed:

therefore: a new intersection-procedure has to be deﬁned:

Are there any other solutions to this problem ?

It is corrected with Maple 6. (U. Klein)
