A model database can contain many models. Although you can have only one model database open at any time, you can open more than one model at a time. The main window's title bar displays the name of the model database, and the title bar of each viewport displays the name of the model associated with the viewport. The current viewport is indicated by a red border; the model associated with the current viewport is known as the current model. The name of the current model is also displayed in the Model list under the toolbar.

To create a new model, select ModelCreate from the main menu bar and enter the name of the model in the Edit Model Attributes dialog box that appears.

To open a model and associate it with the current viewport, select the desired model from the Model list under the toolbar. The Model list contains all the models in the current model database.

To copy, rename, or delete models, select the Copy, Rename, or Delete items listed under the Model menu on the main menu bar. The Copy, Rename, and Delete items contain submenus listing all the models in the current model database. For general information on how to use these menus, see “Managing objects using manager menus,” Section 3.4.10.

You can also create, copy, rename, and delete models using the Model Manager. To display the Model Manager, select ModelManager from the main menu bar. The Model Manager dialog box contains functions identical to those listed under the Model menu but with a convenient browser that lists all the models available in the current model database. For general information on how to use managers, see “Managing objects,” Section 3.4.

You can copy a model to a new model in a model database. In addition, you can copy sketches, parts, materials, sections, and amplitudes between the models in a model database; for more information, see “Copying objects between models,” Section 9.8.3. However, you cannot copy models between model databases.
