Tension Troubleshooter
Set the upper and bobbin tension, or pick a fault preset, and see the stitch from both sides of the cloth with a diagnosis.
Educational simulation
Results are computed from idealised geometry. Real fabric, thread and machines have tolerances and wear, so treat the figures as a guide and always follow the specification on the part.
Loading the 3D model
This tool needs WebGL
This device reports no WebGL support, so the interactive model cannot run. The reference figures below are the same ones the model computes.
| Figure | Value |
|---|---|
| Right side | Balanced |
| Wrong side | Balanced |
| Balance | 100 % |
| Adjustment | None needed |
| Likely cause | None |

Procedure
- Set the tensions, or pick a fault
- Look at the right side
- Look at the wrong side
- Read the diagnosis
- Adjust and re-check

Tension Troubleshooter
Reproduce a tension fault on a 3D stitch and watch which side of the cloth the thread shows on. Compare a correct stitch with a faulty one.
What it models
- Set the tensions, or pick a fault
- Look at the right side
- Look at the wrong side
- Read the diagnosis
- Adjust and re-check
What you can export
- The tension diagram as PNG
- The diagnosis as CSV
Exports are produced in the browser from the current model state. Nothing is uploaded.
Degradation
Without WebGL this page shows a static reference panel carrying the same figures and the same procedure. On a narrow screen the 3D model is offered rather than loaded automatically, so a phone on a slow connection is not forced to download it.
Other 3D tools
Stitch Simulator
Drag to rotate the cloth, set the stitch length and tension, and see the seam build up — including what happens when the tension is wrong.
Pattern Drafting Simulator
Enter your measurements and draft a bodice, skirt or sleeve block, with the seam allowances and the fabric estimate drawn on.
Fabric Drape Simulator
Choose a fibre and a weight and watch the cloth fall, then compare two fabrics to see which drapes and which stands up.
