Construction Group
A Construction group is a set of features that you create with the purpose of making a particular measurement. A Construction group defines a UDA.
A Construction group can have features of any type. If a construction group includes a field point, the analysis is defined over the domain of the field point.
Rules for creating a construction group:
Only one field point is allowed in a Construction group, and it must be the first feature in the group.
The last feature in the group must be an Analysis feature.
