CaldereriaOnLine

CaldereriaOnline is an online platform for generating sheet metal flat patterns used in fabrication and metalworking. The tool allows users to quickly create developments for cones, square-to-round transitions, elbows, pipe branches, and other common geometries found in ducting, process equipment, and industrial fabrication.

The platform is designed for fabricators, engineers, and technical professionals who need practical solutions for real workshop situations. Users can input geometry parameters and obtain accurate developments ready for layout, marking, or CNC cutting. Many patterns can be exported as DXF files for direct use in laser, plasma, or waterjet cutting systems.

CaldereriaOnline.com includes a library of development types ranging from simple shapes to more complex configurations, including offset geometries and intersections. The site offers a flexible access model with free (freemium) patterns, trial options, and paid download packs depending on user needs.
