In today’s engineering and manufacturing workflows, sharing 3D design data must be simple, secure, and accessible to everyone involved. CAD professionals often need to present complex Inventor models to clients, suppliers, project teams, and stakeholders who may not have Autodesk Inventor or native CAD software. ProNexa by ProtoTech Solutions solves this challenge with a web-based solution that converts Autodesk Inventor 3D models into interactive 3D PDFs online. Developed for Inventor users, ProNexa makes design review, collaboration, documentation, and approval workflows easier and more efficient. Even without Autodesk Inventor installed or an active Inventor license, users can convert existing Inventor models into shareable 3D PDFs directly from the web.
