      STP files transfer between different CAD systems more accuratly

      Hi

      What about STL?

      Hi skan. I'm afraid the question "What about STL?" belies a fundamental misunderstanding about CAD systems in general and this debate in particular. Sorry, I don't want to sound patronising but there is very clear division between nurbs based CAD and mesh files of all types. STL is a mesh, originally developed for Rapid Prototyping (Now called additive manufacturing or miss-named 3D printing) machines. Mesh files are also common amongst programmes designed for visuals, games and on-screen applications but all proper CAD software, especially parametric systems primarily work with nurbs. The 2D equivalent is the difference between bitmap images and vector based graphics or between a scanned document and an editable text file. Both have their uses and limitations but they are not interchangeable.

      Based solely on the success of different file types, I prefer STEP. IGES has always been a pain!

      I always prefer STEP because of smaller file size.
      Thanks

      STEP data is the best, since it retain the Solide geometry even after translation, IGES good for sufarce data translation
