Hi, That does not seem to work, it gives all sorts of spurious/weird Z coords. Basically all I want is a constant Z value if I click Anywhere on the face of a shape no matter if I have rotated the shape around. I want it to be relative to the centre of the shape and not the world.

Surely it should be 1 all over !. Hi, the method getPointCoordinates will give the point relative to the origin of the system of the cube (each TransformGroup "define" a coordinate system below it). To get the absolute coordinates you have to use getPointCoordinatesVW.
