Group

Feature Description

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

Group operation on same or different type objects generates a new compound. Objects of the same type can be grouped in line/polygon layers. Objects of different types can be grouped in CAD composite layers.
For the newly generated compound's attributes: System fields (except SmUserID) are assigned by the system. The SmUserID field and non-system fields inherit corresponding information from the object with the smallest SmID value among the grouped objects.
Supports grouping geometries across layers.
Point objects cannot be grouped in point datasets.
When the number of overlapping areas is even, the combined area appears white and remains part of the result data.

With the layer editable, select two or multiple objects.
Click Group in the Feature Editing group's Gallery Control under Features Tab.
Or perform the following:

Right-click selected objects and choose Group from the context menu.


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

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

Notes:

After grouping in polygon layers, overlapping areas appear white but remain integral parts of the result.
When grouped polygons have inclusion relationships, they are processed as donut polygons with corresponding results.
