Hi! 

I just started using the ZPL and what I would like to do is to create a solve based on a very simple geometrical relation. But, for doing this, I need to get the Tilt Y of a rectangular object (I am in NS mode).

The only think I found is the numeric function NPAR, which it seems to me it only acquires parameters.

What would be the right way to do it?

Thank you!!!
