You may change the behavior of the active Intent model in several ways:

Launch the Design Editor from the ETO panel on the Tools tab to edit designs.

Use Parameters... to modify parameter values on an existing Intent part.

Use Add Child... to add a dynamic child to the selected part in an existing model.

Use Change Root Design... to replace the design of the top level assembly with a different design. Optionally, you can delete dynamic rules and dynamic children while changing the root design.

Use Edit Child Rule to show the source of the rule that creates the selected part. The rule source is displayed in either the Design Editor (for a design child) or the Dynamic Rule Editor (for a dynamic child).

Use Edit Dynamic Rules... to view and edit the dynamic rules on the selected Intent part.

Use Delete Dynamic Rules to remove the dynamic rules on the selected Intent part.

Use Import Model File... to import a previously exported model (*.ikm) file into the current model at the selected node.

Use Revert All to reload all design (*.iks) files from disk, which is especially useful when modifying designs using an external editor.
