Creating a new parts list in Civil 3D is essential for managing pipe networks and structures, such as stormwater, sanitary systems, or other utility designs. Here's a step-by-step guide to create a new parts list in Civil 3D:br br 1. Understand the Parts Listbr A Parts List is a collection of predefined pipe and structure parts with specific sizes, materials, and other properties. It's used to standardize pipe network designs.br br 2. Steps to Create a New Parts Listbr Step 1: Open the Toolspacebr If not visible, open the Toolspace palette using the TOOLSPACE command.br Go to the Settings tab in Toolspace.br Step 2: Access Pipe Network Settingsbr In the Settings tab, expand the Pipe Network category.br Right-click Parts Lists and choose New.br Step 3: Name the Parts Listbr In the Parts List dialog box, enter a meaningful name for the new parts list (e.g., "Storm Sewer Parts List" or "Sanitary Sewer Parts List").br Step 4: Add Pipe Partsbr Go to the Pipes tab in the Parts List dialog box.br Click Add Part Family to include pipe types such as:br Circular pipesbr Elliptical pipesbr Rectangular pipesbr Once you add a part family:br Select a material (e.g., concrete, PVC, HDPE).br Define specific sizes (e.g., diameters, lengths).br Step 5: Add Structure Partsbr Switch to the Structures tab.br Click Add Part Family to include structure types like:br Circular manholesbr Rectangular inletsbr Junction boxesbr Specify structure types and sizes.br Step 6: Customize Partsbr For each part in the list:br Set properties like material, size range, and labels.br Use the Part Properties section to refine details such as:br Minimum and maximum diameters.br Default render materials.br Step 7: Save the Parts Listbr Once all parts are added and customized, click OK to save the parts list.br 3. Applying the Parts Listbr When creating a pipe network:br Go to the Create Pipe Network dialog box.br Select the newly created parts list under the Parts List dropdown.br The pipe network will now use the selected parts list for all pipes and structures.br 4. Tips for Managing Parts Listsbr Standardize Across Projects:br br Save parts lists in a Civil 3D template (DWT) for reuse across multiple projects.br Validate Part Sizes:br br Ensure that part sizes and materials align with design standards.br Update as Needed:br br Right-click on a parts list in the Toolspace and select Edit to modify it.br Video Tutorial Ideabr For your Civil 3D YouTube channel, create a tutorial titled:br "How to Create and Manage Parts Lists in Civil 3D: Step-by-Step Guide"br You can demonstrate:br br Accessing the pipe network settings.br Adding pipes and structures to a parts list.br Applying the parts list in a real project.
