Automatic Vector Groups.

GR-Relationships offer a selection of Auto-Vectors to help visualize Point deviations and deviations between features. These include:

Fit Geometry to Points (AVF) These vectors show the individual deviations between the measured points and the fit geometry. It helps visually display the quality of the fit.

Nominal Geometry to Points (AVN)  This Auto Vector type displays the deviations between the measured feature and the nominal feature. It can be shown as either:

  1. Nominal to Fit Cardinal Points. The deviation of the cardinal points of the fit geometry from the axis or surface of the nominal geometry. This provides a minimal number of vectors to clearly illustrate the relative misalignment of the features. For planes the vertex points are used rather than the cardinal points.

  2. Input Points. The deviations of the measured points as directly compared with the nominal feature as if it were the fit feature. This shows both deviations in form and location.

  3. Nominal Cardinal Points To Fit. (Cylinders Only) This option more closely reflects the results of a GD&T inspection in that it dis- plays the deviations extrapolated beyond the fit cylinder to the extents of the nominal cylinder.
