Shell Rolling Master develops open-seam shells from plate:
- Accept OD or ID diameters, height, thickness, K-factor, and weld gap.
- Compute neutral diameters and the flat blank (rectangle or annular sector).
- Visualize a thick 3D shell and a dimensioned 2D pattern.
- Export PDF reports, DXF cut paths, and STEP solids.
All processing runs in the browser. Current version: 0.21.0.
- Start with the user guide for operational behaviour.
- Read calculations for engineering definitions.
- Use domain model and architecture when extending code.
- Consult export formats when integrating CAD or host shells.
- Follow development for local setup and deployment.
