Fabrication Calculator

Fabrication Calculator is a complete, practical workshop companion designed for fabricators, welders, fitters, sheet-metal workers, technicians, and estimators. Access 57 specialized calculators across 7 categories, eliminating the need to switch between multiple apps or manual formulas.

From complex 3D flat pattern developments to quick plate weight estimates and DXF CAD exports, get the estimated numbers and markings you need to cut, bend, and fit with complete confidence.

Key Features & Workshop Capabilities

• 57 Specialized Calculators: Covers flat patterns, dish ends, pipe branches, flange layouts, and shop math.
• Interactive 2D & 3D Visuals: Inspect 2D flat layouts, marking point tables, and interactive 3D models before cutting.
• CAD & Vector Export: Export supported geometry to DXF and SVG for CNC cutting, or generate PDF, PNG, and CSV reports.
• Smart Measurement Validation: On-screen guide diagrams show exact dimensions, with automatic error-checking to catch invalid inputs.
• Metric & Imperial Support: Seamlessly switch units with built-in fraction support and kerf compensation settings.
• Save, History & Favorites: Bookmark your most-used tools and reload saved jobs with preserved unit settings.

Included Calculator Categories

• Flat Patterns: Full & truncated cones, eccentric cones, transitions, miter elbows, reducers, pipe branches, and square-to-round developments.
• Dish Ends: Torispherical, ellipsoidal, hemispherical, and specialized vessel head profiles.
• Pipe & Branch: Equal/unequal pipe intersections, tee branches, lateral/inclined branches, and miter cut layouts.
• Nozzle & Flange: Pitch Circle Diameter (PCD) bolt layouts, hole spacing, nozzle orientation, and shell positioning.
• Coils & Special Fabrication: Spiral coils, limpet pipe developments, and specialist geometry.
• Weight & Material: Surface area, volume, capacity, and instant weight calculations for plates, pipes, and structural sections.
• Workshop Tools: Decimal fraction charts, unit converters, material density guides, circumference, arc, angle, and division tools.

Production-Ready Exports

Export calculation data directly to your workflow:
• DXF & SVG: Send vector line work straight to compatible CAD/CAM software for laser, plasma, or waterjet cutting.
• PDF & PNG: Share clean dimensioned drawings and layout reports with shop workers or clients.
• CSV Tables: Download detailed marking point coordinates for manual layout mapping.
