With the Caliper tool, you can measure the exact distance between two points on a model or a curve.
To measure between points on a model
Mudbox displays the two points as small crosshairs on the mesh. You can drag points to adjust their position.
The distance between the two points displays as a HUD message. To stop viewing the HUD value, click an empty area off the model, or select a different tool.
To measure between points on a curve
A temporary HUD message displays two different measurements, one value for the distance directly along the curve, and one value for the linear distance between your first and second points.
