I need to extrude a simple shape between two planes and then get the length as a parameter. Is there anyway of generating this? All I can find is a parameter for the angle of the extrusion.
Did you look for the dimension here? This is where you can rename it to make it easier for locating it.
I don't a parameter is created when you do a between extrusion (I may be wrong). Can you instead find the distance between the planes? If they're offset planes, then the offset values are parameters. You could create a user parameter for the extrusion distance and assign it a value of Plane 1 offset1 + Plane 2 offset.
