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 Layout<br />1. Set Up the Drawing<br />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 Tools<br />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 Settings<br />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 Tools<br />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 Structures<br />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 Pipes<br />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 Elevations<br />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 Refinement<br />Pipes and structures have grips that allow for fine-tuning placement, alignment, and elevations.<br />9. Review and Edit the Network<br />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 Tools<br />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 />Tips<br />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.
