There are several creation dialogs and submenus available in the modeling tool:
- Element Creation dialog and/or submenu are available via the Create Element command. The dialog and submenu display a list of commands for creating specific elements.
- Relationship Creation dialog and/or submenu are available via the Create Relation command. The dialog and submenu display a list of commands for creating specific relations.
- View Creation dialog and/or submenu are available via the Create View command. The dialog and submenu display a list of commands for creating specific views.
The corresponding commands are available in the element shortcut menu displayed upon right-clicking an element.
Instead of using predefined creation dialogs that come with the modeling tool, you can create custom model-based creation dialogs listing only the commands of your choice, allowing you to customize the creation dialogs based on the needs of your specific project.
