All elements are organized by group. For example, walls are grouped under Exterior Walls, Interior Walls, or Foundation Walls. This helps you locate specific element types quickly. You can add groups to any catalog using the Add Group tool.
To add a group to the current catalog:
Select File > Catalogs > Catalog Manager, or right-click an element in the catalog panel and select Catalog Manager.
Select the appropriate element type from the Element drop box.
Select Catalog > Add Group, or right-click in the Select a Type window and select Add Group.
Type a name for the group, then press ENTER.
