How to Download Routing Library for NX 12
What is the Routing Library in NX 12?
The Routing Library in NX 12 is a set of tools, components, and workflows used to design and manage electrical, mechanical, and piping routes in 3D assemblies.
It allows users to create wire harnesses, pipe systems, tubes, HVAC ducts, and conduit runs with intelligent components and logical connectivity.
It is a key module in the NX Electrical Routing, NX Piping Routing, and NX Mechanical Routing environments.
Uses of Routing Library in NX 12
🧰 1. Electrical Routing
-
Design 3D wire harnesses, connectors, and terminals
-
Automatically route wires using logical connections from ECAD systems (e.g., Capital, Zuken, etc.)
🔧 2. Piping & Tubing Routing
-
Model pipes, tubes, elbows, tees, reducers, valves, and flanges
-
Auto-generate pipe paths between fittings with bend radii, standard sizes, and flow direction
🛠️ 3. Mechanical Routing
-
Design rigid mechanical systems, including HVAC ducts, trays, and cable carriers
📦 4. Component Library Integration
-
Use standard fittings and parts (DIN, ANSI, ISO) for industrial projects
-
Insert parts like connectors, couplings, tees, and instrumentation valves
Benefits of Using the NX 12 Routing Library
-
✅ Automated Routing – Auto-route connections based on logic or physical constraints
-
✅ Integrated with NX Assembly – Place routes inside full assembly models
-
✅ Reuse Component Libraries – Import standard catalogs or create custom parts
-
✅ Associative Modeling – Changes to path or component auto-update entire route
-
✅ Generates BOM & Nailboard Drawings – Ideal for manufacturing & documentation

NX Routing Workflow: How It Works
-
Open Routing Application
Switch to the desired Routing environment: File → New → Electrical/Piping/Mechanical Route -
Load Parts from Library
Insert fittings, connectors, pipes, or ducts from the Routing Library -
Define Logical Paths
Use Path Segment, Route Path, and Auto Route to create geometry -
Assign Specifications
Set pipe size, wire gauge, bend radius, or material properties -
Validate & Simulate
Check bend violations, clearance, and continuity -
Generate Reports
Output BOM, wire length, and nailboard drawings

❓FAQs
Q1: Is NX Routing Library available in all NX versions?
No. It’s a separately licensed module (ERW/PRW/MRW) in NX 12.
Q2: Can I import external ECAD data (like from Capital)?
✅ Yes, NX Electrical Routing supports ECAD integrations (Capital, Zuken, Mentor).
Q3: Can I export routing designs to manufacturing?
✅ Yes, routing can export BOMs, wire cut lengths, pipe specs, and 2D drawings.
🔗 Conclusion
The Routing Library in NX 12 is a must-have for anyone working on 3D wire harnesses, piping systems, or mechanical routes. It increases design speed, reduces errors, and ensures manufacturing-ready documentation — all within the Siemens NX platform.
