CAD Exchanger is a technology that enables data exchange in the multi-CAD world.

From startups to Fortune100 companies our products are used to view, convert and collaborate on 3D CAD data.

Serving users from 110+ countries

CADEX was founded in 2014, although the first release of CAD Exchanger dates back to 2009. The company was founded by Roman Lygin, a veteran with 20+ years of experience in CAD data exchange, parallel computations and project management.

Our story is one of steady growth thanks to dedication, hard work and passion to solve problems in CAD. We try to make CAD Exchanger the tool of choice for end-users and developers. We strive to make it world-class yet easy-to-use and affordable.

We are proud to have customers both from startups and Fortune 100 companies. We understand the responsibility of enabling 80,000+ direct users and hundreds of thousands of those who use our SDK customers’ apps.

We are not #1, so we try harder. We are younger than our entrenched competitors, so we try harder. We love what we do and we try harder. Nothing compares to receiving users’ feedback like these:

'Hello heroes! We found your product by accident and fall in love with it ;)'

'Enjoying your software. This makes a complicated process so simple.'

'First of [all] I wanna tell you that I m really impressed by your CadExchanger. Recently I needed to convert several …[files] and I tried many Apps to do so. Yours is by far the fastest.., easy to use and most UI-intuitive app of all.'
