So I have a sculpture I made in SW from a 4x8 sheet of steel. I started with the sheet, and split the shapes out of that sheet and used those resulting shapes in an assembly to create the sculpture. In the original sheet I assigned the material as plain carbon steel. The problem is it wont calculate the mass properties of the shapes in the assembly more than one at a time : Unable to compute mass properties. is what it says. It will do it one at a time but why not 2 or 3 or 10 shapes at a time. Its so laborious to have to print out 10 mass properties pdf's. Can someone help? '

Also I find that sometimes from the original sheet (plain carbon steel)to the saved off split part it loses the mass materials (material ) any ideas how I can keep the material on the split the same as its original ? Thanks in advance!-ethan http://www.midnightmetalworks.comSolidworksAssemblies
