2 In the tree view, navigate to and select a block-based part. 3 To add a new part size to an existing part, click . The block-based building environment is opened and the MvPart Builder (Add Part Size) dialog is opened. The process is the same as that of creating a new part. IMPORTANT The 3D model blocks created for the new part sizes must exist in the part family DWG file stored in the catalog. 4 To modify a part, click . The block-based building environment is opened and the MvPart Builder (Modify Part Size) dialog is displayed. This dialog has tabs that enable you to change only what you need to change, in any order. 5 To delete a part, click . The selected part family is deleted from the part catalog, including all associated definition files (XML file, DWG file, and BMP file). Modifying a Block-Based Part As your design develops and parts change, you can add new part sizes or modify existing part sizes using Content Builder. When you add a new part size, you are guided through the process step by step. When you modify an existing part size a tabbed dialog enables you to change only what you need to change. For more information, see Approaches to Creating Parts on page 643. For each part size, you can change the 3D model block, schematic symbol, part behavior, view blocks, preview image, connectors, and property set information. You can use the same procedures that guide you through creating a block-based part to modify it. This section outlines how you can modify a block-based part and provides references to related procedures that you can use. Modifying the 3D Model Block and Schematic Symbol You can change the 3D model block of an individual part size. You can edit the existing 3D model block or create a new 3D model block for one or more part sizes. Changing the 3D model block requires that you regenerate the view blocks for the part size to ensure the correct display of the part in a drawing. For more information, see Creating a 3D Model for a Block-Based MvPart on page 755. You can also change the schematic symbol that is assigned to the part size or attach a new schematic symbol. When you change the schematic symbol, you are changing it for all part sizes in the part family. For more information, see Creating a 2D Schematic Symbol for a Block-Based MvPart on page 756. NOTE All changes must be made in the part family DWG file stored in the part catalog prior to starting Content Builder. When modifying an existing 3D model block, modify the block stored in the part family DWG file. When replacing an existing 3D model block with a new 3D model block, delete the existing block and then add the new block in the part family DWG file. Modifying the Part Behavior You can change the part behavior that defines how the part is added to a drawing, including type, subtype, layer key, and insertion method. You can make changes to a single part size or to multiple part sizes. For more information, see Defining the Part Behavior of a Block-Based MvPart on page 757. NOTE Avoid making changes in the Behavior tab or page in the parametric part wizard unless you want to change the behavior of the part family. Any changes you make to the part family affect every part size for that part. Modifying Block-Based Parts Using Content Builder | 765
