Lesson Summary: LRF-DUCT-01-03 – All About Rectangular Duct P1
🎯 Lesson Focus:
This lesson dives into the essential setup and understanding of rectangular ductwork in Revit, specifically using the Snowden Tower sample HVAC file included with Revit 2025. It emphasizes the critical first steps before modeling ducts, ensuring that everything is configured properly.
🧠 What You’ll Learn:
✅ 1. Understanding Duct Types & Fittings
Overview of how rectangular duct types are organized in Revit.
Where to find standard fittings like elbows, tees, transitions, and how they relate to duct systems.
⚙️ 2. Routing Preferences
How routing preferences control what fittings Revit chooses during layout.
Why getting these preferences right before modeling saves time and avoids cleanup later.
🖥️ 3. New Revit 2025 Browser
Introduction to the new Family Browser/Filter UI in Revit 2025.
Demonstration of how to search and filter duct families quickly using the updated interface.
🔧 4. Mechanical Settings Are Critical
Reinforces that Mechanical Settings (under the Systems tab) must be configured correctly before using:
Layout Path
Generate Duct
These tools depend on those settings to produce correct results.
🧩 Bottom Line:
Before drawing a single duct or clicking “Generate,” the lesson stresses that preparing your Mechanical Settings, routing rules, and fitting families is absolutely essential. Doing so ensures your ductwork is clean, accurate, and coordinated.
