3D TUBE TO 2D DXF.
Automatically.
Automatic Tube Unbender converts the actual geometry of finished, already-notched straight round tubes from STEP into flat 2D cutting profiles. No manual seam required.
Import. Analyze. Export.
No rebuilding the notch. No matching against another tube. ATU works from the geometry you already modeled.
Import the STEP model
Load one finished straight round tube or a STEP file containing multiple tube bodies.
ATU analyzes the geometry
ATU identifies the individual tubes, their dimensions and the actual boundary geometry of each end profile.
Export flat DXF profiles
Export the resulting 2D geometry for your preferred CAM software, CNC, plasma or other cutting workflow.
Built for one job.
ATU stays focused on the awkward bit between finished CAD geometry and a usable flat cutting profile.
Automatic tube geometry detection
Designed for straight round tube geometry imported from STEP.
Multi-body STEP support
Import and process multiple tube bodies from a single STEP file.
Existing end-profile recognition
Uses the actual modeled result instead of asking you to recreate notch parameters.
Tube dimensions detected automatically
OD, ID, wall thickness and tube length are read from the imported geometry.
Flat profile generation
Transforms cylindrical boundary geometry into usable unwrapped 2D coordinates.
DXF export
Outputs clean profile geometry ready for the next step in your fabrication workflow.
See the geometry, not the marketing.
This is the real application processing real STEP geometry. No mockup, no reconstructed notch parameters.
One tube. One complete workflow.
The STEP input, the ATU analysis and the actual DXF output below are all from the same tube.
1. Finished STEP geometry
A straight Ø28 × 2 mm tube with two different modeled end profiles.
2. ATU analyzes it
Tube geometry, dimensions, end profiles and rotation are detected from the actual model.
3. Flat DXF profiles
Two separate open profile curves, ready for the next step in the cutting workflow.
Process the assembly, not separate files.
Import a STEP model containing several solids. ATU identifies the straight tube bodies and processes them in the same run.
This real subframe model contains 24 solids in total. ATU finds the 16 tube bodies, processes all 16 successfully and exports their profiles.
YOUR CAM IN.
ATU is not CAM software and it does not generate machine toolpaths.
It handles the geometry conversion, then gets out of the way so you can continue in the CAM package and machine setup you already use.
Try it on your own tubes.
