ProNexa by ProtoTech Solutions: Convert Inventor 3D Models to Interactive 3D PDFs Online Without Autodesk Inventor

Why did we develop ProNexa?
In today’s engineering and manufacturing environment, sharing 3D design data should be simple, secure, and accessible. CAD professionals often need to communicate complex product designs with clients, suppliers, project teams, and stakeholders who may not have access to Autodesk Inventor or other native CAD software.
To address this challenge, ProtoTech Solutions developed ProNexa, a web-based application for Autodesk Inventor users, in June 2026. ProNexa enables users to convert Inventor 3D models into interactive 3D PDFs, making design review, sharing, and collaboration easier and more efficient.
But the question is, why ProNexa?
If you do not have Autodesk Inventor installed or do not have an active Inventor license, ProNexa works as an independent web-based solution. If you already have a 3D Inventor model and want to convert it into an interactive 3D PDF without using Inventor, ProNexa is the right tool for your workflow.

ProNexa currently supports Autodesk Inventor 3D model conversion into interactive 3D PDFs. Future enhancements aim to support additional formats such as OBJ, STEP, JSON, WebGL, and more.
Whether you are working on product design, manufacturing documentation, client presentations, design reviews, or internal engineering communication, ProNexa helps make your 3D models more accessible.
With ProNexa, your 3D model does not remain locked inside a CAD environment. It becomes an interactive document that can be opened, viewed, rotated, zoomed, and reviewed using standard PDF viewers.
Why 3D PDF Matters for CAD Professionals
Sharing native CAD files is not always practical. Recipients may not have dedicated CAD software installed, file sizes can be large, and there may be concerns about sharing editable design data.
A 3D PDF solves many of these challenges.
It allows CAD professionals to share interactive 3D models in a format that is easy to open, lightweight, and suitable for technical communication. Stakeholders can view the model, inspect it from different angles, and understand the design intent without needing advanced CAD tools.

Key Features of ProNexa
Convert Inventor Models Without Installing Autodesk Inventor
ProNexa allows users to convert existing Autodesk Inventor 3D models into interactive 3D PDFs online without installing Autodesk Inventor or requiring an active Inventor license on their system.
Web-Based Access
As a web app, ProNexa offers a convenient way to convert 3D models without requiring complex installation steps. Users can access the tool online and convert their models through a simple workflow.
Easy 3D Model Sharing
Interactive 3D PDFs are easy to share with customers, suppliers, internal teams, and project stakeholders. This makes design communication faster and more effective.
Better Design Review Experience
Instead of sending screenshots or static drawings, ProNexa helps users share an interactive model experience. Reviewers can rotate, zoom, and inspect the 3D model directly inside the PDF.
Professional Documentation Support
3D PDFs are useful for technical manuals, product documentation, assembly instructions, design reports, and project submissions. ProNexa helps make documentation more visual and informative.
Future-Ready Multi-Format Conversion
Our developer team is continuously enhancing ProNexa. The upcoming roadmap includes support for converting 3D models to multiple formats, including 3D PDF, OBJ, STEP, JSON, WebGL, and more.
This future upgrade will make ProNexa a more flexible and powerful solution for CAD data conversion, visualization, and sharing.
