Modifying Block-Based Parts Using Content Builder You can use Content Builder to modify an existing block-based part. You can modify the entire part family or an individual part size. Once the part has been saved to a catalog, any modifications you make using Content Builder are made directly to the source files stored in the catalog. You can modify the 3D model block and/or symbol; you can also modify the model and schematic symbol of the part size. You can redefine a part size based on a new 3D model block and reassign the schematic symbol of a part size based on a new symbol block. NOTE When you modify existing part sizes in a part catalog, your changes apply only to part sizes that you add to a drawing after the part catalog is modified. Part sizes existing in a drawing are not affected. You should use Content Builder to modify individual part sizes wherever possible. Starting Content Builder for Modifying a Block-Based Part Use this procedure to start Content Builder and open the block-based building environment for modifying a block-based part. IMPORTANT When adding new part sizes to an existing part family, you must add the new 3D model blocks to the existing DWG file for the part family prior to starting Content Builder. The DWG files for a catalog part are stored in the \ProgramData\Autodesk\MEP 2010\enu\Tool Catalogs folder, in the appropriate part catalog subfolder. For example, to add a new part size to the Gas Fired Roof Mounted AC Unit, add the new 3D model block to \ProgramData\Autodesk\MEP 2010\enu\MEPContent\USI\MvParts\Mechanical\Roof Mounted AC Units. 1 Click Manage tab ➤ MEP Content panel ➤ Content Builder .
