SKP to STEP Converter

The tool converts SketchUp SKP models into STEP CAD format to enable cross‑platform collaboration and manufacturing handoff. It accepts a single SKP file, supports optional unit mapping and explicit schema selection, and outputs a standards‑compliant STEP file ready for import into major CAD systems. Outputs include geometry, assembly structure hints, and a basic property set.
Core processing parses SKP geometry and builds STEP representations. It reads vertices, edges, faces, and groupings, then constructs STEP entities such as Brep topology and assembly references. It preserves topology and approximate geometry within a defined tolerance, applies unit scaling, and ensures consistent axis directions to minimize downstream adjustments. Optional features include schema selection, assembly retention, and optional geometry simplification for large files. The tool is designed for mechanical, architectural, and product-design workflows needing reliable data exchange.
Advanced options provide schema choice (AP203 or AP214), geometry simplification controls for large assemblies, and assembly export behavior. Certain SKP features map poorly to STEP (e.g., textures, complex materials), which are either omitted or tagged for later enhancement. The tool performs pre-flight checks, reports incompatibilities, and fails gracefully if critical elements are missing. The target users include mechanical engineers, product designers, architects, and fabricators who need reliable handoff between SketchUp and STEP workflows. Its value lies in predictable conversion, validation of resulting STEP files, and compatibility with common CAD packages, enabling faster design iteration, fewer reworks, and smoother data exchange across teams and suppliers.
