Vector Groups
A vector group is a graphical depiction of the magnitude between points and objects. It is often displayed with arrows (whiskers) showing the deviation and direction from the object to the point. It can also be magnified to more clearly display relative deviations in very small numbers.
Vector groups are build in the following ways...
-
By using Query. This the most common method and creates a vector group that represents a snapshot of the deviations be- tween points and objects.
-
Auto-Vectors created with a relationship. Relationships can update a vector group so that rather than being a single measurement event the vector group is always update to display the current deviations.
-
By construction. At any time a snapshot of an auto-vector can be captured or there are additional construction commands to build or combine vector groups together.

Projection Options
The projection options dialog can be seen in several places in SA but is mainly used in Query Points to Objects and relationships. The projection options allow the user to control vector group direction, add material offsets, create offset point groups, and change probe offset compensation.
