Hey @balintzs,

A few things that come to mind, in no particular order of importance.

Arc length is displayed when an arc or edge is selected in the 3D space, but it can’t be annotated in the 2D space, only arc angle. I realize in the 3D space it’s not necessary displaying arc length specifically, just the length of a curved edge or line.

The second, which is not necessarily a measurement issue, but a measurement labeling improvement.

If a whole body is selected, it’s body name is displayed with the relevant measurements.

If one feature of a body is selected, it doesn’t display the body name it’s part of. It would be helpful to show this, particularly when zoomed in with multiple bodies on screen.

Third would be handling of .XXXX” measurements, from this recent thread.

I understand that internally Shapr is capable of using these tolerances, however when viewing the object, the resolution is viewed as 0.001” regardless of the number of decimal points entered. Shapr3D is advertised as having power and capability comparable to other ‘professional’ cad/cam software - I understand that most people using this won’t need to work at .0001” tolerance, bu…
