General Use of Diagrams
For the general use of diagrams, Innovator often offers alternative procedures that you can use depending on their suitability for your purpose.
Creating New Elements in the Diagram
There are many ways to create a new element: A respective create template is always the basis for this.

You can customize create templates for elements in the configuration.
A unique name is created and selected for elements with names.
Note
Diagram elements can only be renamed if the model language is set as display language. If required, change the language by clicking the flag in the status bar.

Option 4: Creating in the model structure and then dragging into the diagram

Adding Existing Elements to the Diagram
You can add existing elements using the Model Contents, Details, Bookmarks or Result Region tool windows. The element you want is selected and then dragged to the diagram using drag-and-drop.
Selecting Elements in the Diagram
You can select elements in the diagram using the mouse and keyboard.

You can overwrite configured display options for diagram content locally in the Display Options dialog. The settings apply for all elements of the same type within the active diagram.
For certain diagram contents, the display can differ in the two dialog modes (Edit Mode (F6) or Read-Only Mode (Ctrl+F6)).
For classifier diagrams, you can use the display options to display the multiplicity of the roles of associations. In each case, only explicitly made settings are displayed. The default value (1) is not displayed.
To enable the easier editing of the roles of associations, the multiplicity of roles is always displayed in Edit Mode, including the default value (1) if appropriate. Only the use case diagram also displays content in accordance with the display options in Edit Mode.

Select the element you want to remove from the diagram and select Design>Edit>Remove from Diagram (Del). This removes the element from the diagram but does not delete it from the model. The element still exists in the model structure or in other diagrams too.
Please note that subelements cannot be separately removed.

Select the element you want to delete from the model and select Design>Edit>Delete from Model (Shift+Del). The Delete from Model dialog box appears and lists all the elements that are affected by the command. You can add elements to the Result Region without deleting them. If you confirm the element list with the Delete from Model button, all elements listed are deleted from the model.

The diagram can be as big as you want so you have the option of looking at a section of the diagram. Scroll bars do not exist. The Diagram Overview shows the respective diagram section that can be seen in the document window in a black box. You can move these black frames in the Diagram Overview using the mouse.
You can move the diagram in the diagram editor with the mouse. This allows you to control the section of diagram you can see.
see "Moving a Diagram in the Document Window"
Changing the size of a diagram also has an effect on the diagram section.
