🌿 Civil 3D Canal Design – Part 5: Fixing Corridor Links & Updating Section Views

Welcome to Part-5 of the Irrigation Canal Design Project in Civil 3D.
In this post, we address an important part of the design process: solving corridor subassembly link problems and ensuring that your section view groups reflect accurate canal geometry.

🔧 Why This Step Is Important:

If your corridor does not display correctly—missing slopes, gaps in cross-sections, or broken subassembly links—your volume calculations and material quantities will be incorrect. This step ensures all elements are properly linked and ready for the next stage.

📌 Step-by-Step Process:

🔹 Step 1: Check Corridor Subassembly Links

Open the Corridor Properties and examine each region.
If side slopes or bottom links are missing, check subassembly placement or target settings.

🔹 Step 2: Fix Link Connection Issues

Adjust the assembly insertion point and verify link-to-link connections.
Rebuild the corridor after editing.

🔹 Step 3: Update Section View Groups

Go to Sample Line Groups → Section Views.
Use the Update Section View tool to reflect the corrected corridor shape.

🔹 Step 4: Visual Check of All Sections

Scroll through the cross-section views to ensure the canal shape is consistent throughout.
If needed, reprocess the corridor or adjust assemblies again.

📘 Coming Up in Part-6:

Assigning materials to corridor components
Earthwork and volume calculation
Attaching volume tables to section views
Exporting volume report (XML) for project documentation

🎯 Conclusion:

Fixing corridor link issues and updating section views is a must before doing earthwork calculations. It ensures accuracy and saves rework time.
