Group > Ungroup All Levels (Modify Menu)

This command can be used to break up groups. Their objects are then treated as individual objects again

The groups to be broken up must be chosen. Click on groups to choose them.

All of the groups contained in the chosen objects are broken up; all other objects remain unchanged. All levels of groups are broken up, so if a group is nested (i.e. it contains more groups), all the sub-groups will be broken up, too.

Older groups that were created with a version prior to Release 2017 will be shown as internal blocks with a name starting with "#G" upon opening the drawing. They cannot be resolved using this command, please use Library > Block > Resolve All Block Instance Levels instead. In order to convert old groups into the current format, use the Modify > Groups > Create Groups form Block Instances command.
