I am unable to measure a diameter of a solid object or determine its volume in mm^3. How might i do this?
You can measure radius of something like a sphere with the Radius command. Radius only works on curves, so you need to find a seam edge to measure. You could also measure diameter with the Distance command and the appropriate object snaps.
The Volume command will allow you to measure volumes of closed objects; if you run the command without objects pre-selected, you will see options for different unit reporting. Objects must be closed in order for this to work.
And the result shows up in command history.
Yes, thanks for adding that, on Mac, the panel for the results is so small, people often miss it…
