Who are we?

Theorem is an independent privately owned organisation which has been providing solutions to the world’s leading engineering and manufacturing companies for over 25 years. Fundamentally we help companies extract greater value from their 3D CAD assets.

CAD assets contain what is probably for every engineering company its most valuable asset, its intellectual property. Intellectual property is what makes a company different from its competitors and valuable to its customers.

Consider the asset value, based on cost. If you have 10 CAD seats and have been using them for 20 years and an engineer with overheads costs $100,000, based on cost alone, your IP is worth $20 Million! That has to be a good reason to want to extend its value, and Theorem has the products and technology to do that. For over 25 years we have been enabling CAD users to extract extra value from their 3D CAD assets.


Where it all began.

We began by translating complex 3D CAD assets between the leading 3D Mechanical CAD systems, to solve the problem of supply chain collaboration across different CAD systems.

That process was extended to take those assets in to lightweight visualization systems, like 3D XML, Creo View and JT, to enable internal users and suppliers to visualize 3D CAD data on the desktop without access to a CAD seat. We then enabled mechanical CAD users to load their JT data in to native CAD for data sharing and design in context processes.

As 3D publishing products became available we delivered solutions to publish 3D CAD in to documents, particularly PDF documents.

That was in support of Model Based Engineering processes, sharing data using the free PDF viewer and the creation of a wide set of engineering documents such as; Work Instructions, Training materials, RFQ’s, Technical Data Packages and Sales and Marketing material.



For the last 5 years we have further extended the value of those 3D CAD assets by enabling them to be used in eXtended Reality (XR) Experiences, allowing engineering companies to collaborate within innovative Virtual, Augmented and Mixed Reality Experiences.

We believe that XR will dramatically increase value creation by combining the strengths of humans and machines. These solutions can be leveraged by product development and manufacturing engineers today.


Our Strengths

Our greatest strength is our dedicated and skilled staff who have in depth knowledge of engineering and manufacturing processes, and the skills of our development team to turn that in to high quality practical solutions for our customers.

We combine that with our close working relationships and support from our technology partners to deliver quality products of high fidelity, with PLM vendor back up and support.
