2 To specify the part type, under Part Configuration on page 653, right-click Undefined, click Edit, and then select Tee. Example of part configuration for round duct beveled tee You specify the part type (such as tee, elbow) from a predefined list in the part browser. The selection is based on the building system domain and current part catalog. You can also enter a new subtype. Part subtype is a sub-category of part types. You can either specify a part subtype from the predefined list or you can enter a custom part subtype. NOTE Part domain defines the family of parts, such as pipe, duct, cable tray, conduit, MvPart components. Domain is predefined based on the part catalog you selected in the Getting Started Catalog Screen dialog. This value is read-only and cannot be changed. For more information, see Part Configuration of a Parametric Part on page 653. 3 To specify the part subtype, right-click Undefined, click Edit, and select Transition Straight. Modeling a Parametric Fitting Modeling on page 654 is used to create the parametric content, constraints, and dimensions. To model a parametric part, you follow this sequence: ■ Establish work planes on which to create the geometry of your model ■ Create profiles and apply modifiers to define the shape and default size of the part. To avoid distortion in the model, start with the larger features, which have more impact on the overall size of the part and then add the smaller features. For example, for a tee fitting, you first create the trunk of the tee and then add the branch. Establishing the Work Planes of a Parametric Fitting Work planes on page 654 define the orientation in which you are working. They provide access to views, such as Front, Side, Top, etc., that let you create content. Use this procedure to add work planes to create the geometry, paths, and constraints of a model. To avoid confusion, work with only one work plane visible, unless you are using offset or reference work planes. The following instructions refer to the part browser. The part browser is located under the ribbon to the left of the drawing area. 1 In the part browser, expand Modeling. 2 Right-click Work Planes and click Add Work Plane. The Create Work Plane dialog appears. Building Parametric Fittings Using Content Builder | 677
