Simulating Cross Rails within IS&V

[Jcamsystems]

I’ve cobbled together a generic UGPOST/ISV lathe driver to give me the facility to use the simulations module within NX Cam which appears to work extremely well for the majority of our lathe configurations. The problem that I am having at the moment is with VTL’s with adjustable cross rails. I need to find away of positioning the cross rail within NXCAM/IS&V Model (which is probably going to be via a ude), but my real issue is how to pass this information to the IS&V driver so the simulation works correctly. Does anyone have any examples of how to do this sort of thing
