Opinion
vtkBoxWidget
I found that CATIA's compass very intuitive to use compared to the vtkBoxWidget. The compass too is fixed in the upper right of the main screen and can be dragged and dropped to any object/point. The representation helps the user to rotate/translate either the entire scene or the linked object. My only gripe with this tool is that when a rotation nears 180degrees, the interactive part of the tool allowing further rotation is hidden by the bulk of the tool.
vtkAngleWidget, vtkDistanceWidget
The measurement tools found in CATIA are far more complex than the vtk widgets. In CATIA, distances can be measured between points, lines, curves, surfaces etc. Also, measurements may be linked - so you can measure a simple distance, chain a series of measurements for a total, or even compare distances between different sets of points. Angle measurement also features more - measure between points, lines, curves, arc and surfaces. The user can even select to measure complimentary angles.
