The measure command in ProtaStructure is significantly improved so that you can snap to any 2D and 3D points, including line intersections, solid object vertices, extensions, intelligent element points, axis intersections, and so on, and measure the distance between them.
The measure command will immediately mark the points with coordinate labels and provide information on parameters like the Distance, Distance in X, Distance in Y, Distance in Z, Angle in XY Plane, and Angle from XY plane.
To measure the distance between two points in 3D view:
