Dynamic Geometry are a type of Geometry Relations that uses other objects or features for its computation. Like Comparison Only relationships they do not provide an option to select points but only evaluate the selected features for the computation.
Beginning in 2022 Fit and Compare geometry relationship can be converted to a Comparison Only relationships and vice versa.
To associate geometry:
Ensure that the geometry relationship has a nominal defined
Clear any prior point or cloud associations
Right-click and select Associate Data>Measured Geometry
There are a couple of differences between Fit and Compare and Comparison Only relationships which are as follows:
AVF Vectors are disabled and AVN vectors are switched to Nominal to Fit Cardinal Points, if enabled.
Projection Plane will no longer be an option
Desired Measurement Count to -1. Trapping is currently not available for Comparison Only features.
Point List and Fit reporting is also disabled.
Clearing the measured geometry association with re-activate this capability.
