I was creating a material cost comparison spreadsheet for aweldment and noticed the spreadsheet calculated weight is 28%lighter than the Solidworks mass property. The weldment is full oftrimmed features.

I used the SW cutlist lengths in the spreadsheet.

Is SW using the non-trimmed length to calculate the length? If so,then the actual weight and CG of the part will be different thanthe SW mass property. Yikes!SolidworksBill Of Materials
