Note that both the STEP AP214 and the legacy AP203 formats are supported by Altium Designer – exported files are ISO-10303-21 -compliant (AP214). This provides the basis for the free exchange of high-quality, standardized 3D modeling data between software domains, which simplifies ECAD-MCAD design collaboration and enhances both the quality and accuracy of 3D model data. At the fundamental file exchange level, Altium Designer offers both export and import capabilities for 3D STEP files. The STEP file format itself ( *.step or *.stp) is defined in the ISO 10303-21 (International Organization for Standardization) specification for CAD data exchange and is supported by the majority of MCAD tools and systems. The range of systems and interfaces that bridge the ECAD-MCAD domains also rely on standardized data formats such as the industry ratified STEP protocol ( Standard for Exchange of Product model data), which provides an information-rich, clear text encoded file format for 3D model design data. Altium Designer offers advanced capabilities for interacting with mechanical design systems and software (MCAD) through the active exchange of physical design data.
