How It Works

reaConverter offers the fastest, simplest solution for converting your U3D files into PDF without 3D or CAD software - all models processed on your PC for maximum privacy and speed.

Technical note

Before you convert U3D to PDF

PDF holds pages, which makes it a natural container for a review of a model from several sides. With Create multiple frames switched on in the 3D formats loading settings, each step of the turn becomes its own page, so one file shows the part from every angle you set and opens on any device. For a technical sheet, Create 2D projection gives the isometric, top, front or side view as a line drawing.

3D Workflow

From 3D model to PDF

Turn U3D models into PDF sheets for design reviews, quotes and archives. Set the views once, and every model in the folder comes out the same way.

  • Show the model from several angles in one PDF: each step of the turn becomes its own page
  • Draw isometric, top, front or side views as line drawings with 2D projection
  • Keep unreleased designs and client models on your PC: nothing is uploaded

PDF is certainly a universal format, but sometimes you need JPEG files instead. For conversion, I use reaConverter - a lightning-fast program. No online editor can match its speed. Install it once, and you're set. Just open, convert, and done!

I needed to convert a 200‑page PDF into individual JPEGs for a client presentation. reaConverter did it in under a minute. The quality was superb – each page looked like a print. I'm genuinely impressed by the speed and reliability.
