Conversion quality notes (read before converting)
- CAD → Mesh (STEP/IGES/BREP → STL/OBJ/PLY): may lose parametric features; output becomes triangles.
- Mesh → CAD (STL/OBJ/PLY → STEP/IGES/BREP): may produce surfaces/approximations depending on engine.
- If output looks broken, try converting to STEP first, then to your target format.

PLY
Polygon File Format is a widely used file format for representing 3D data, particularly polygonal meshes, in the fields of computer graphics, 3D scanning, and point cloud data. It was originally developed to store data from 3D scanners and has since gained popularity in both academic and commercial applications due to its flexibility in handling a variety of data types.
IGES
Initial Graphics Exchange Specification is an early and widely used file format standard for the exchange of 2D and 3D CAD (Computer-Aided Design) data between different software applications. It was developed by the U.S. National Institute of Standards and Technology (NIST) in the 1980s to allow interoperability between different CAD systems.
