Binds elements so that you can locate, select, and manipulate them as a unit. Grouped elements are usually related, such as the holes and center lines of a bolt hole pattern. When you select a group, the Group ribbon is displayed so you can edit the entire group or any of its members. The command is only active when one of the following conditions is met:
An element or set of elements is selected
More than one group are selected
A group and another element are selected
In Catalog Manager, you cannot save a symbol with grouped elements. Therefore, you must ungroup all grouped elements before saving the symbol.
