A modern, easy-to-use CAD file converter built with PythonOCC and PyQt5. Convert STEP, IGES, BREP, and STL files seamlessly with a batch mode and a sleek GUI.

If you think about it, STL files are like PDF files. You usually create them using some other program, export them, and then expect them to print. But you rarely do serious editing on a PDF or an STL.
