Edit Pipe Network Catalog in Civil 3D | PVC to GRP & Structures

🛠️ How to Edit Pipe Network Catalog Using Part Builder in Civil 3D

Convert PVC Pipes to GRP Pipes & Customize Structures

If you're working on a pipe network project in AutoCAD Civil 3D, you may need to modify default pipe parts or structures to meet project-specific requirements. In this tutorial, we’ll show you how to use Part Builder to convert PVC pipes to GRP (Glass Reinforced Plastic) pipes and also customize structure parts (like manholes or junctions) in your catalog.

🔄 What You'll Learn:

How to access and use Part Builder in Civil 3D

Rename and modify existing PVC pipe parts to represent GRP pipes

Change key parameters like material, inner diameter, wall thickness, etc.

Edit structures like manholes, including size and naming conventions

Apply and test the modified parts in a real Civil 3D pipe network

📝 Step-by-Step Instructions:

✅ Step 1: Open Part Builder

Go to Home tab > Parts List > Launch Part Builder

Choose the part family you want to edit, for example: Pipe > PVC Pressure Pipe

✅ Step 2: Clone and Rename the Part

Right-click the pipe part and select Clone

Rename it to something like GRP_Pipe_100mm

✅ Step 3: Edit Parameters

Open the part's parameters section

Change the material from PVC to GRP

Adjust dimensions (inner/outer diameter, thickness) as per GRP specs

✅ Step 4: Modify the Structure

Switch to Structures tab inside Part Builder

Clone and rename the structure part

Edit values like base diameter, riser height, or frame type

✅ Step 5: Save & Apply

Save your changes

Restart Civil 3D (or reload catalogs)

In your Parts List, select and use the updated GRP pipe and structure in your design
