How Do You Ungroup All Groups in AutoCAD?

To ungroup objects in AutoCAD, you typically use the UNGROUP command. While there isn't a single built-in command to ungroup all groups in an entire drawing simultaneously with one action, you can achieve this by selecting all the groups you want to ungroup and then using the standard ungroup process.

Here's the fundamental method, incorporating the provided reference:

Ungrouping a Selected Group

The standard procedure to ungroup one or more selected groups in AutoCAD involves these steps:

1. In the drawing area, select a group (or multiple groups). You can select multiple groups by holding down the Shift key while clicking on each group, or by using a selection window that includes the groups.
2. In the command line, type UNGROUP and press Enter.

Executing the UNGROUP command on a selection of groups will dissolve those specific groups, turning the grouped objects back into individual entities.

Ungrouping Multiple or All Groups

To effectively "ungroup all groups" in your drawing, you need to first select all the groups you intend to ungroup. Follow these steps:

1. Select all the groups in your drawing.
   • You can manually select groups using a selection window that encompasses the entire drawing or the area containing groups.
   • Alternatively, you can use selection filters or quick select to specifically target only group objects.
2. Once all desired groups are selected, use the UNGROUP command as described above:
   • Type UNGROUP in the command line.
   • Press Enter.

AutoCAD will then ungroup all the selected group objects.

Important Note: This method only affects the groups that are currently selected. It does not automatically find and ungroup every possible group definition that might exist in the drawing if they are not currently visible or selectable.

Automation for Ungrouping All Groups

For drawings with a very large number of groups or for repetitive tasks, CAD users often turn to automation using scripting languages like AutoLISP. An AutoLISP routine could be written to iterate through all the objects in the drawing, identify those that are members of a group, and then programmatically ungroup them. However, this requires custom programming and is not a standard command.

In summary, the core method for ungrouping in AutoCAD is the UNGROUP command applied after selecting the desired group(s). To ungroup "all groups," you simply apply this same command after selecting all the groups you wish to dissolve.
