VScad3 Model Manipulation

2.5.5 Probe mode.

This mode is used for making measurements of the model. When entering Probe points with the mouse, it can sometimes be useful to turn on the Grid Snap and/or Geometry Snap to obtain exact measurements about existing entities. The Snap settings can be controlled via the main "Workspace / Grid/Snap..." menu. When a probe is performed, a report pop-up window is created, and it can remain on the screen for reference while other actions are performed. Multiple probe report windows can exist at the same time.

"Type" : This setting determines the type of probe to be created.
In "Point" mode, click the left mouse button on a point. The X,Y,Z coordinate of that point is reported.
In "Vector" mode, click the left mouse button on two different points. The X,Y,Z coordinates, vector length, and angle of the line through those two points is reported. A line between the two points will appear in the view(s) for as long as the associated probe report window still exists. When that window is closed, the probe line is deleted.
In "Two Vectors" mode, click the left mouse button on three different points to draw a "V". The X,Y,Z coordinates, angle between the vectors, dot product and cross product are reported. The lines between the points will appear in the view(s) for as long as the associated probe report window still exists. When that window is closed, the probe lines are deleted.

"Z Plane" : This setting determines the Z coordinate of probe points entered with the mouse (when the Grid/Geometry Snap is off).
