I have a plastic part in SW 2014 Professional. Using "Mass Properties", the volume is reported as 76.93cm^3.
We have a seat of SolidWorks Plastics. I've run my part through analysis, and when the process is complete, the volume is reported as 77.87cm^3.
Why is there a discrepancy between the two? Is the latter the effective volume of the mesh, and not the original SW definition of part geometry? Regardless, why are they different?
(77.87-76.93)/76.93*100 = 1.22% greater volume in SW Plastics. This doesn't seem insignificant.
Bottom line, which should I use for cost estimating material usage? I've always trusted SW to get this right. SW Plastics has disturbed my trust (for now).
