A sample to show how to measure angle with four points. the operations of these items are similar such as Coordinate, Dist N2N, Dist N2S, Dist P2P, Angle 3Node, Angle 4Node, 3Pt Radius, Area, Volume, Mass, Inertia and Ang Vel.
Load a d3plot file. Go to the measure dialog. Select "Angle 4Node" in items choice.
Pick four points orderly on the model, like this,
