Copyright Goodheart-Willcox Co., Inc. 346 AutoCAD and Its Applications—Advanced Creating Drawing Views After setting up a layout and making the appropriate drawing view settings, you are ready to place the base view. As previously discussed, drawing views can be created from a 3D solid or surface model. Drawing views created in the layout are generated from the model you have created in model space. If no model exists in the drawing and you initiate the VIEWBASE command, the Select File dialog box appears. From this dialog box, you can select a model created in Autodesk Inventor. When you select the VIEWBASE command from the ribbon, a preview repre- senting a scaled orthographic view of the model appears. This is the base view of the model. You can then specify the location of the base view or select an option. To select an option, use dynamic input or make a selection from the Drawing View Creation contextual ribbon tab. See Figure 14-3. The Select option switches you to model space and allows you to add objects to or remove objects from the base view. If necessary, use the appropriate option to select solids or surfaces to add or remove. Use the Layout option to return to the layout after making changes. The Orientation option can be used to select a different view from the default base view. The Orientation options correspond to AutoCAD’s six orthographic and four isometric preset views. These views are based on the WCS. By default, the front view is used as the base view by AutoCAD. Depending on the construction of your model, you may want to use a different view, such as the top view, to serve as the base view. In Figure 14-4, the top view of the model is selected as the base view. This view will establish the front view on the orthographic drawing. In most cases, the front orthographic view on the drawing describes the most critical contour of the model. You will typically use the front or top view of the 3D model for the front ortho- graphic view on the drawing. The Type option of the VIEWBASE command is available before picking the initial location of the base view. This option is used to specify whether projected views are placed after placing the base view. By default, this option is set to Base and Projected. With this option, you can place additional, projected views while the VIEWBASE command is still active. Projected views that you place are projected from the base view and oriented in the proper orthographic alignment. As previously discussed, projected views have a parent-child relationship with the base view. The base view is the parent view and any projected views are child views. If the base view is moved, for example, the projected view is moved with it. Projected views are not created with the VIEWBASE command when the Type option is set to Base only. If you place a base view in this manner and later decide to create projected views from the base view, you can use the VIEWPROJ command. The VIEWPROJ command allows you to place projected views from any selected view. After you pick the location for the base view, you can press [Enter] to place projected views (if the Type option is set to Base and Projected). Drag the cursor away from the base view and then pick to locate the projected view.
