STL to IGES Converter

The STL to IGES Converter ingests STL files (ASCII or binary) and produces IGES output suitable for editing in parametric CAD systems. It does not attempt to rebuild solids; instead it translates the mesh surface into IGES representations that CAD tools can modify. Users include mechanical engineers, design teams, and 3D printing specialists who need to exchange geometry between formats for analysis, simulation, or fabrication. The tool emphasizes reliable geometry export and predictable results across common CAD platforms.
Conceptual workflow: parse the STL to extract triangles, apply optional unit scaling, and map geometry to IGES entities. The tool supports typical input units and lets the user specify a target unit for the IGES file. It applies a configurable tessellation tolerance to balance fidelity and file size and can perform basic mesh repairs to improve import reliability in CAD software.
Value proposition: free online access, no installation, and quick turnaround on typical CAD files. It enables cross‑platform collaboration by delivering IGES data that many mainstream CAD systems can import. Ideal for converting scan data, prototype geometries, or legacy meshes into editable IGES models for analysis, simulation, or documentation.
Core features include file upload, unit handling, optional scale and tolerance, IGES export, and a downloadable result. The converter reports basic issues such as non manifold regions or degenerate faces and provides guidance for corrective actions if needed.
