Hello, Elias.
Use IDLgrPolyline, IDLgrAxis, and XOBJVIEW. You will be able to spin
the result with your mouse.

Oh, oh. :-(
You are trying to combine direct graphics and object
graphics which--despite your best efforts--is just
not ever going to work. It just plain can't be done.
Try using the AXIS command instead of creating
an axis object and see if that doesn't get you
further ahead.
Cheers,
David
