Truss Bridge Generator
With the power of Geometry Nodes, the Truss Bridge Generator streamlines bridge modeling in Blender, making it easier than ever to create detailed, customizable structures. This procedural tool allows you to generate truss bridges with full control over length, width, trusses, abutments, and piers. Designed for realistic infrastructure projects, the Truss Bridge Generator saves you time while ensuring accuracy and flexibility, making it an essential asset for 3D artists.
How to Start
Insert a Bezier Curve, set the desired bridge length, and change its handles to Vector for a straight line. Then, apply the Truss Bridge Generator modifier in the Modifier tab.
Full Procedural
The bridge geometry is created procedurally, enabling full customization. This approach ensures great performance and flexibility.
Customization and Features
You can easily adjust the length, width, and height of the truss. Also, abutments and piers can be individually adjusted to fit your specific project needs.
In the Roadway Panel
- Modify road width by increasing or decreasing it.
- The number of lanes is determined by the road width. For example, with a 7-meter road width, set the lanes to 2 (since each lane is 3.5 meters).
- Adjust the footpath width as needed.
In the Truss Panel
- Adjust the trusses' section size by modifying the width and depth.
- The height setting controls the overall bridge height.
- The number of sub-bridges divides the bridge into smaller equal bridge lengths.
- The number of bays should be such that the inclined member is at 45 degrees (between 30 to 60 degrees is acceptable).
- You can create a Pony Truss Bridge by turning off the top bracing switch.
In the Abutment
- The Pier Index controls the pier type.
- The Pier Base Index allows you to customize the foundation type.
- Adjust the abutment height and pier height offset to change the overall height of the abutments and piers.
Extra features include enabling lights and adjusting their intensity under Traffic Light, as well as changing the different railing types under Railing as needed.
