Hi Tudor,

> how can i get difference between parallel frames ?

Do you mean the difference in the origin points between 2 coordinate frames?

That would be like this:

var dx = FrameB.origin.x - FrameA.origin.x;
var dy = FrameB.origin.y - FrameA.origin.y;
var dz = FrameB.origin.z - FrameA.origin.z;
