CaldereriaOnLine

CaldereriaOnline is an online sheet metal development tool designed to generate flat patterns for common fabrication geometries used in metalworking and industrial ducting. The platform allows users to quickly calculate and download developments for cones, square-to-round transitions, elbows, pipe branches, and other intersecting shapes typically found in sheet metal fabrication.

The system works directly in the browser and requires no software installation. Users simply enter the geometric parameters of the part and the platform generates the corresponding flat pattern. Depending on the pattern, the output can be downloaded as a printable layout or as a DXF file ready for CNC cutting with laser, plasma, or waterjet systems.

CaldereriaOnline is intended for fabrication workshops, mechanical engineers, CAD technicians, and industrial designers who need a practical way to obtain accurate developments without performing complex manual calculations. The platform supports a wide range of geometries used in ducting systems, process equipment, hoppers, and general sheet metal assemblies.

A key feature of the system is its ability to handle not only basic developments but also more advanced configurations such as offset (eccentric) transitions and intersecting branches. This makes it useful for real workshop situations where parts are not always centered or symmetrical.

The platform offers a flexible access model. Some patterns are available under a freemium option, allowing users to test the tool and download certain developments at no cost. Additional patterns and downloads are available through trial access and download packs, allowing users to scale usage according to their needs.

By automating the generation of flat patterns, CaldereriaOnline helps reduce calculation time, improve accuracy in fabrication layouts, and streamline the preparation of parts for production.
