As shown in the previous illustration, the default position of the Symbol and Annotation plane on the Z axis in the World Coordinate System (WCS) is high above the WCS origin. This keeps the plane and its contents out of the way while you are working on your part model. If desired, you can change the Z position of the plane. To do so, right-click the plane in the part browser, click Change Plane Position, enter a new value for the Z position, and press ENTER. Creating Schematic Symbols for Parametric MvParts 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. For more information, see Creating a Schematic Symbol of a Parametric MvPart on page 735. Workflow for Creating a Parametric Fitting with Content Builder This workflow provides a road map for creating a parametric fitting using Content Builder. Review the steps View more information Open the Parametric Building Environment to start building content. You use the Content Builder in AutoCAD MEP to ----- create a parametric fitting. See Opening the Parametric Building Environment on page 676. Specify the part configuration. You work in the parametric building environment to create single parametric parts. In this environment, only one part can exist in a ----- drawing. The individual drawings are associated with a part catalog to build a library of parts. You specify the type and subtype of the part to establish basic part behavior. See Defining the Part Behavior of a Parametric Fitting on page 676. Create a 3D model of the part. You create models of 3D parts and use them to dynamically generate 2D views of your parts. You build your part from blocks, or features, that are parametrically combined to define the part. The model is defined in terms of the size, shape, and ----- position of its features. You can restrict how the features of the parts fit together. To better conceptualize the size and shape of the part model, you define constraints and dimensions that determine how your part is built.
