Gear Shifter Essentials

The Gear Shifter is a crucial component in automotive design, particularly within the engine, drivetrain, or chassis systems. It plays a key role in ensuring optimal vehicle performance, safety, and efficiency. Engineers typically model this part in high-detail CAD formats such as STEP or IGES to support simulation, manufacturing, and assembly processes. By using digital models, teams can validate this component's fit, function, and integration before physical prototyping. Leveraging digital tools like Marathon-OS allows cross-functional teams to review, track, and collaborate effectively on this part throughout its lifecycle.

Why they cant view CAD files?

Most non-technical roles lack access to expensive CAD software, powerful computers, or the technical skills to handle large or complex CAD files. They often rely on engineers for screenshots or simplified versions, which slows down collaboration and decision-making.

The Solution: Marathon-OS CAD Viewer

  • To bridge this critical access gap, Marathon-OS offers a cloud-based CAD viewer that requires no installation, no heavy hardware, and no expensive licenses.
  • Whether you're a field technician using a tablet, a procurement manager reviewing part specs, or a project coordinator needing design clarity, Marathon-OS lets you view and interact with complex CAD files (STEP, IGES, STL, BREP, OBJ, PLY, OFF) right from your browser.
  • By converting CAD files into lightweight visual representations, it makes collaboration seamless across engineering, manufacturing, and business teams — bringing CAD accessibility to everyone, not just engineers.
