Opens the measurement tool.
The following measurement modes are available:
- Location: get accurate 3D coordinates of a point in a given coordinate system.
- Distance: get 3D distance and height difference between two points.
- Area: get polygon area and contour length.
- Volume: get volume measurement between the 3D model and a reference plane in a polygon.
For each measurement mode, several measurements can be performed and displayed in the 3D view.
