Convert STP to IGS

The STP file extension stands for "Standard for the Exchange of Product Model" (STEP) and is used for 3D CAD files. Developed by the ISO in 1984, this format facilitates the exchange of digital models between different CAD systems, enhancing interoperability and collaboration in engineering and manufacturing. STP files store 3D object data in a text format that includes geometric and functional product information, supporting various stages of Product Lifecycle Management (PLM). They are widely adopted in industries such as automotive, aerospace, and industrial design for sharing complex 3D models.

The IGS file extension refers to the Initial Graphics Exchange Specification (IGES), a standardized ASCII-based format developed by the United States Air Force under the ICAM (Integrated Computer-Aided Manufacturing) program in the late 1970s. Designed to facilitate interoperability among diverse CAD systems, IGS files store 2D and 3D vector data including wireframes, surface models, and engineering drawings. Widely adopted across aerospace, automotive, and defense industries, IGES became an ANSI standard in 1980 and was instrumental in streamlining digital product data exchange. Although superseded by newer formats like STEP, IGS remains relevant for legacy system compatibility and long-term archival of CAD data.
