Geometry Relationships (GR-relationships) allow for dynamic fitting and comparison of geometry. Unlike standard geometry construction operations, GR-relationships will update the size and position of the geometry as measurements are either added or removed from the relationship and any comparison with a nominal geometry is also automatically updated.
The report options for the relationship are composed of a list of specific Criteria. The check boxes on the left provide a means to include or exclude these computed values from the resulting report. The order of the criteria listed can also be adjusted by selecting a row and using the Move Up or Move Down buttons on the right.
The Mag XYZ criteria criteria is an example. If deviations in 3D are desired this computes the absolute distance in XYZ of the working frame between the nominal and measured elements of this features. However, if you are using a projection plane you may only want to report the Mag XY criteria below it. The check boxes can be used to switch the criteria reported in the report table shown below.
In addition, tolerance and relationship optimization settings can be accessed for each individual criteria by double clicking on a selected row.
Tolerance settings are absolute if no nominal reverence is available and no delta can be computed. When a nominal is available, they are relative and evaluated with respect to the delta value.
In addition to the criteria tolerance settings there are a set of check boxes controlling report table parameters including:
Show High and Low Tolerance in Report
Show Point List Details In Report
Show Nominal & Measured in Report
Show Fit Settings in Report
Show Units in Report Title
Each criteria has the ability to be used in a relationship minimization. This allows a user to fine tune a relationship fit based on geometry components. An optimization can be performed using Delta and / or the Amount out of Tolerance.
Pressing the Edit button will open a master overview panel that facilitates editing of a selection of criteria at one time. It includes reporting settings, callout settings, and relationship fit parameters.
