Does anyone know how accurate the mass number is when you run a mass properties on a single part? I have a plastic piece created and would like to know how much material would be required to make that piece. When I run the mass properties report it give me a specific weight of roughly 52 grams. I have set the density of the material to the manufactures specs but I am not sure if that is all that is needed. If I weigh the finished piece I have a large discrepancy between the two. The other problem will be the next piece which is a foam and will expand in the mold cavity. It has a completely different density altogether. Is this even possible?
This is a new area for me.
