The Measure tool toggles measurement mode, enabling you to measure distances on a model.
Click on the model at the point from which you would like to measure. Click again on the model at the point to which you want to end the measurement.
The coordinates of each point, distance measured, and vector are instantly updated.
The coordinates of the point will appear in the Start box.
The coordinates of the second point, the measured distance between the two selected points, and the vector between the two points are displayed.
