About MCAD Groups
You can select parts and subassemblies for four types of groups:
• Static—Groups parts and assemblies that you select.
• Nested—Creates a group of groups. It can contain static, nested, search and rule groups. The Nested group appears in the Groups pane with its child groups.
When you select a nested group, all the members of all of its children appear under Part Name. When you select a child group, only its members appear in the Part Name partition.
You can delete only entire child groups from a Nested group. You cannot delete parts individually.
• Search—Saves the results of a search as a group in the Part Name partition of the Groups pane instead of in the Part Name partition of the search results pane.
• Dynamic—Defines criteria to subdivide MCAD groups according to the hierarchy of parts or the value of a specific attribute. For instance, a group called Motor_Parts subdivided according to the attribute material, will have subgroups called Motor_Parts_steel and Motor_Parts_aluminum.
Create a Dynamic group without parts, import the parts from an existing MCAD group, and then select the criteria for inclusion into the subgroups.
