Creating pipes and structures by layout in Civil 3D involves designing a pipe network that connects structures like manholes, inlets, or junctions. The process includes defining the alignment, placing pipes and structures, and editing the network to match design requirements.br br Steps to Create Pipes and Structures by Layoutbr 1. Set Up the Drawingbr Ensure you have a surface (e.g., ground surface) and optionally an alignment to guide the pipe network layout.br 2. Open the Pipe Network Creation Toolsbr Go to the Home tab.br In the Create Design panel, click Pipe Network Create Pipe Network from Parts List.br 3. Configure Pipe Network Settingsbr In the Create Pipe Network dialog box:br Name: Provide a name for the pipe network.br Parts List: Choose a parts list that contains the desired pipes and structures.br Surface: Select the surface to assign elevations for structures.br Alignment: If applicable, choose an alignment for the pipe network.br 4. Open the Pipe Network Layout Toolsbr After creating the pipe network, the Pipe Network Layout Tools toolbar appears.br Use the following tools:br Create Structures: Add structures like manholes or inlets.br Create Pipes: Add pipes between structures.br 5. Start Adding Structuresbr Click Create Structures on the toolbar.br Click on the surface or alignment to place the first structure.br Continue clicking to add structures where needed (e.g., intersections or inlets).br 6. Connect Structures with Pipesbr Click Create Pipes on the toolbar.br Select a structure as the starting point.br Click to place the pipe endpoint at another structure.br Repeat for all pipes in the network.br 7. Adjust Elevationsbr Civil 3D assigns default elevations based on the surface. To adjust:br Use the Pipe Network Vista (accessible from the Modify tab) to edit structure and pipe elevations.br Set invert elevations and slopes as required.br 8. Use Grips for Refinementbr Pipes and structures have grips that allow for fine-tuning placement, alignment, and elevations.br 9. Review and Edit the Networkbr Use the Prospector to view and edit the pipe network.br Switch to profile view to inspect the vertical alignment of pipes and structures.br 10. Generate a Profile View (Optional)br Create a profile view of the pipe network:br Go to the Home tab Profile & Section Views Create Profile View.br Add the pipe network to the profile to review its interaction with the surface and other features.br Additional Toolsbr Analyze Gravity Network: Automatically adjust pipe slopes and sizes based on hydraulic calculations.br Apply Rules: Apply design rules to ensure pipes and structures meet standards.br Export to Hydraflow Storm Sewers: Analyze the pipe network in hydrology and hydraulics software.br Tipsbr Use a well-prepared Parts List to ensure the availability of appropriate pipe and structure types.br Use Surface Flow Analysis to pre-determine drainage paths before creating the pipe network.br Keep the network in Plan and Profile Views simultaneously to ensure proper connectivity and elevation.
