Group
Feature Description
The Group function combines any objects (geometries of the same or different types) in the current layer into a compound.
- Combine same or different type objects to create a new compound. Objects of the same type can be grouped in line/polygon layers. Different type objects can be grouped in CAD composite layers.
- For the new compound's attributes: System fields (except SmUserID) are assigned by system. SmUserID and non-system fields inherit corresponding information from the object with the smallest SmID value in the group.
- Supports grouping geometries across layers.
- Point objects cannot be grouped in point datasets.
- When overlapping areas have even counts, they appear white in results and remain part of the result data.
Feature Entry
- Features Tab->Feature Editing Group->Group.
- In map->Context Menu->Group button.
Steps
- Ensure layer is editable, select two or multiple objects.
- In Features Tab's Feature Editing Group Gallery control, click Group to combine selected objects.
Or perform following operations:
Right-click selected objects, choose Group from context menu.

- Merge works on same-type objects, while Group works on different-type objects.
- Merge cannot process point objects, while Group can process text and point objects.

- After grouping in polygon layer, overlapping areas appear white which are part of result data, not missing data.
- When grouped polygons have containment relationships, they are processed as donut polygons with consistent results.
