So at my school we've started this project to create a charm bracelet. The job of our class is to design the charms in solidworks. Eventually once they are finalized and approved, a local jewelry company is going to cast our designs in gold. Each charm is supposed to composed of a specific amount of the gold. I'm pretty sure there is a feature in solidworks that allows you assign a value of volume to a part specific to a certain material and it will size it for you to meet those requirements. If this exists, could somebody share a link to a basic instruction list of how to do this? If my question is too vague to answer, let me know and I'll to explain what I need more clearly.
