So it is 2.5D

Phil
Reading that wiki definition is still not clear!

e.g.
This statement in wiki is very clear - In machining, 2.5D refers to a surface which is a projection of a plane into 3rd dimension - although the object is 3-dimensional, there are no overhanging elements possible.
This statement in wiki is confusing - A 2.5D machine possesses the capability to translate in all three axes but can perform the cutting operation only in two of the three axes at a time.

It seems to be saying that a 2.5D machine can only cut with 2 axes in operation, and the third fixed.
Yet the first statement indicates that it can cut at full 3D as long as there are no overhangs.

I'm probably misunderstanding - but feel the definition could be clearer.
