7 Select a different view from the list, or click to view the model using 3D orbit navigation. 8 In the Parametric Object Viewer, select a point on the circle, and drag the cursor along the circumference of the circle to inspect the 3D model dynamically from various viewpoints. 9 With the Parametric Object Viewer open, select a different part size in the Size Parameters dialog. The part size is displayed in the viewer. 10 Inspect the model from various viewpoints to verify that the model appears sound. If your inspection reveals problems, such as segments that join improperly, make the necessary modifications, and inspect the part sizes again. Repeating this process until all part sizes appear sound. 11 Click to close the Parametric Object Viewer. Creating a Schematic Symbol of a Parametric MvPart You can create a schematic symbol for a parametric MvPart at any time. However, only parts that you add to drawings after you have created the symbol can use the symbol. You cannot update previously inserted parts to use the symbol. There are 2 types of schematic symbols that you can add to parametric MvParts: ■ Parametric. This type of symbol scales proportionally with the part. You create parametric symbols using parametric features: parametric geometry, dimensions, and constraints. ■ Block-based. This type of symbol scales uniformly instead of proportionally. You create block-based symbols using standard AutoCAD® objects, such as lines, arc, and circles. You can create the symbol from scratch, or you can insert an existing AutoCAD MEP symbol or 2D AutoCAD block from a DWG file. This allows you to take advantage of existing symbol libraries or block libraries. Creating a Parametric Symbol 1 If necessary, open the parametric MvPart in Content Builder. 2 In the part browser, right-click Symbol and Annotation Plane, and click Visible. NOTE Although this step makes the plane visible in the drawing area, its position on the Z axis in the World Coordinate System (WCS) is high above the WCS origin, so you might need to zoom out to view the plane. You can also change the position of the plane if desired. 3 Right-click Symbol and Annotation Plane, and click Set View. This changes the view direction to Top (plan) view, which is the default view for the plane as well as the most common view for drawing schematic symbols. However, you can select any view that is helpful for drawing the geometry. 4 Create the schematic symbol using parametric geometry, constraints, and dimensions. First, use the model geometry that changes with part size to create point references and projected geometry on the Symbol and Annotation plane. Next, create the symbol geometry on the plane. Finally, add constraints and/or dimensions so that the symbol changes accordingly when the part size changes. To access the necessary commands, expand Symbol and Annotation Plane, right-click Parametric Graphics, and use the commands on the context menu, as follows. Click Add Geometry, and then click Point Reference. Building Parametric MvParts with Content Builder | 735
