distance between coords

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   How do I define the distance between two coordinate systems relative to each other with one of them as the base? This must also work if the base coordinate system moves and rotates. The coords lie on different bodies.
For example I need the x and y components of coord[1] regarding the base coord[2].
I couldn't figure it out with the express formula.

	I found the solution in an earlier post: express(coord[1].p-coord[2].p,0,2).x express(coord[1].p-coord[2].p,0,2).y
