Thank you for the tip about Normalize. David did go through this
but I still wanted to understand how the location/coordconv stuff
works.

I run some tests at home and found out that the Location-keyword
sets two coordinates out of three. And the coordconv sets the
third coordinate, range and the scale.

range = [-50 150]
normalized_len = 1.6

Location = [not_valid y_pos z_pos]
scale = normalized_len/(range[1]-range[0])
Xcoordconv = [x_pos - range[0]*scale, scale]

This does not sound logical to me. I would rather see:

Location = [x_pos, y_pos, z_pos]
Scale = normalized_len/(range[1]-range0])
Offset = -range[0]*scale

Perhaps RSI could add "scale" and "offset" to make the objects behave
like the user expects them to work.
