Calculating silver weight on Rhino

Jewelry Discussion
1

Can one work out what the final weight of a silver piece will be in
grams, from a rhinoceros 3d model?

Tracey,

Take the volume of the model using: Analyze/mass properties/volume.

Take the volume and plug it into the formula: 1.015*((VOLUME /1000)
X11) = object weight sterling silver to convert to cast weight.

Deselect all items, type in Volume on the command line then click on
the units option and select Centimeters then select your item. The
volume in cubic centimeters will be displayed. Multiply the volume
by 10 to get the weight in grams for sterling.

Hey Paul this only works if your model units are in millimeters as
the menu Volume command does not allow you to change units like the
command line one will. I assume the 1.015 is a fudge factor.

Analyze > Mass Properties > Volume = Cubic MM. Multiply by. 01049 for
grams of silver

Or the plug-in Rhinogold calculates any metal very easily just by
selecting the piece. It will also show cast piece weight versus
finished.
