A Group must be selected for the ungrouping option to be enabled. To ungroup a set of grouped figures:
Select the set of figures to be ungrouped.
Press on the Arrangement Button in the Top Toolbar.
Both grouping buttons will appear in the Arrangement Menu when an individual figure and group of figures has been selected at the same time.
Two selected figures will appear as shown below after they have been ungrouped.
Note: Any transformations made to the group (such as rotating, resizing, etc...) will be retained by previously grouped objects after the ungrouping action has been completed. Grouping provides a nice way to quickly make bulk changes to multiple figures or all objects within a drawing.
