Group

Function Description

The Group function combines any objects (geometries of the same or different types) in the current layer into a compound.

The group operation on objects of the same or different types generates a new compound. Objects of the same type in line and polygon layers can be grouped. Objects of different types in CAD composite layers can be grouped.
In the attributes of the newly generated compound, system fields (except SmUserID) are assigned by the system. The SmUserID field and non-system fields inherit the corresponding information from the object with the smallest SmID value among the objects participating in the group.
Supports grouping geometries across layers.
In point datasets, grouping point objects is not supported.
When the number of overlapping surfaces of objects is even, this area appears white after grouping and is part of the result data.

Edit Data tab -> Feature Editing group -> General editing -> Group and Ungroup -> Group
In the map -> context menu -> Group button.

With the layer editable, select two or multiple objects.
In the Edit Data tab, under the General editing drop-down menu, click the Group button in the Group and Ungroup group to group the selected objects.
Or perform the following operations:

Select the two objects to be merged, right-click, and choose the Group command from the context menu.


Original Objects	CAD Layer Group Result	Polygon Layer Group Result	Union Result

Merge can only operate on objects of the same type, while Group can operate on objects of different types.
Merge cannot operate on point objects, while Group can operate on text objects and point objects in CAD.

Notes:

After performing a group operation in a polygon layer, the overlapping areas of polygon objects appear white, which is part of the result and not missing.
When polygon objects being grouped have inclusion relationships, they are treated as donut polygons, and the result is consistent with that of donut polygons.
