We are working on updating ModelCHECK for go live of Creo 7. We are upgrading from Creo 5. Now that a default material is assigned in Creo 7 we are looking for another way to flag a material not being assigned. I thought using MATERIAL_DENSITY check would work however it is always an error or always a warning. It seems like the density is always reported as 0.000000 for the material card even though there is an actual value. Has anyone had any luck with this check in Creo 6 or 7? What am I missing?
