Scale by Volume

Hollywood83

Is it possible in OnShape to scale a part uniformly by volume rather than by axis? The transform>scale option scales by axis with a vertex as its point of origin for the scale. However, I'm needing to "swell" a part by a few percent for a sla printer to account for resin shrinkage,

There should be an option to scale uniformly:

Here is how you can scale by volume: 

You will need the custom feature Measure Value by @konstantin_shiriazdanov found here:

• Measure the volume of the original part with Measure Value
• Create a variable for the desired new volume
• Create a variable for the scale factor. Divide the new volume by the old measured volume
• Scale the part uniformly using the transform feature like Tim mentioned. Use the scale factor variable that you calculated
