Features

📐

Multi-Bend Design

Create tubes with multiple bends and straight sections. Each segment is fully customizable with precise control over lengths, angles, and rotations.

🔄

Axial Rotation Control

Rotate the tube around its axis before each bend to create complex 3D paths. Perfect for roll cage designs and architectural applications.

📊

Real-Time 3D Preview

See your bent tube design in an interactive 3D view. Rotate, zoom, and inspect your design from any angle before fabrication.

⚙️

Precise Measurements

Specify tube diameter, wall thickness, straight lengths, bend radii, and bend angles with exact measurements for accurate fabrication.

📏

Centerline & Outer Dimensions

View both centerline (CL) path dimensions and outer geometry dimensions with X, Y, and Z measurements in both the 3D view and PDF reports.

🎯

Bend Schedule Table

Automatic calculation of bend positions, centerline radii, axial rotations, bend angles, springback compensation, and developed length for accurate fabrication.

Professional PDF Reports

Generate comprehensive bend reports with 3D isometric view, bend schedule table, and orthographic projection views (top, front, and side) with centerline and outer dimensions.

How to Use

1

Define Tube Specifications

Enter your tube's outer diameter and wall thickness. These parameters define the tube profile that will be swept along your path.

2

Add Straight Sections

Start with a straight section and specify its length. You can add more straight sections between bends throughout your design.

3

Add Bends

After each straight section, you can add a bend. Specify the axial rotation (rotation around the tube's axis), bend angle (0-180°), and centerline bend radius.

4

Build Complex Paths

Continue adding alternating straight sections and bends to create your complete tube design. The 3D preview updates in real-time.

5

Review & Fabricate

Review your design in 3D, verify all measurements, and use the specifications to fabricate your bent tube.
