To Add a Relation to a Model
1. With a model open, click Tools > Relations. The Relations dialog box opens.
2. The Look in box shows the type of object (for example, part or feature) where the relation is applied. If you are in Part mode, by default the relation is added at the part level. You can change the object type by changing the selection in the Look in box, for example, you can change feature relations or section relations.
If the pattern_relations_copy configuration option is set to true, the relations defined for the geometry to be patterned are copied to other instances of the pattern.
3. If you selected Feature, Inherited, Section, or Pattern as the object type, you must select the object for which you want to list relations. The selected object shows dimensions in symbolic form.
4. Type a relation in the text box and press ENTER. You can type multiple relations by pressing ENTER after each one. Use the following tools for adding a relation:
