Function Description

Ungroup one or more complex objects or compounds. The result of ungrouping can be single objects or complex objects.

• The ungroup feature applies to line layers, polygon layers, text layers, and CAD layers.
• Only complex objects or compounds can be ungrouped; simple objects cannot be ungrouped.
• Ungrouping a complex object (i.e., a non-text object containing multiple sub-objects) generates multiple single objects, all of which are simple objects. Ungrouping a compound generates multiple single objects. If the resulting single objects still contain compounds, they can be further ungrouped until all are simple objects.

  The following figure shows a donut polygon. After performing the ungroup operation, the new objects obtained are two single objects:

• For ungrouping a text, you can choose simple split or complete split:
  • Simple split: Decomposes a compound text into multiple sub-object text strings. The left figure below shows a compound text composed of two sub-objects. After simple split, it becomes two texts as shown in the right figure.

  • Complete split: Splits a text completely into individual characters. After complete split of the left figure below, the result is eight single-character texts as shown in the right figure.

• For the attributes of the newly generated objects, the field SmUserID and non-system fields inherit the corresponding information from the source object; other system fields are assigned by the system.

Feature Entry

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

Instructions

1. Under the editable state of the layer, select one or more complex objects or compounds.
2. On the Edit Data tab, in the General editing drop-down menu, click the Ungroup button in the Group and Ungroup group to perform the ungroup operation.

   Alternatively, perform the following operation:

   Right-click and select the Ungroup command from the context menu.

3. If the ungrouped objects still contain compounds, you can continue to use the ungroup feature to ungroup them until all are single objects.
