About STEP Format
Standard for the Exchange of Product model data (STEP) is a 3D file format used primarily for CAD and Manufacturing and Engineering.
STEP (ISO 10303) stores exact NURBS surfaces and solid boundary representations rather than a triangle mesh, so parts keep their true curved geometry and can be re-edited in CAD software after import. It has no concept of animation and only limited, rarely-used color support.
