Tech Soft 3D Completes Acquisition of Theorem Solutions

Acquisition Cements the Company’s Position as the Leading Provider of CAD Data Translation and Re-use for Both Application Developers and End-Users

BEND, Ore.–(BUSINESS WIRE)–#3DCAD–Tech Soft 3D, the leading provider of engineering software development toolkits, today announces that it has acquired Theorem Solutions, makers of advanced solutions for CAD data translation and publishing. This acquisition is in line with the company’s plans to fuel growth by investing in product development, scaling the company’s global reach and increasing its product offerings through acquisitions.

Theorem’s CADTranslate and CADPublish products complement Tech Soft 3D’s HOOPS Exchange and HOOPS Publish software developer toolkits (SDKs), and creates an ecosystem of data translation, publishing and 3D PDF solutions for end-users and developers alike. Additionally, TheoremXR solutions provide capabilities for manufacturers to use their 3D CAD data in extended reality (XR) applications for numerous manufacturing use cases, such as design review, factory layout and more.

“We have long admired and appreciated Theorem’s deep expertise in CAD data exchange and have had a chance to work closely with the team as they created their solutions,” said Ron Fritz, CEO of Tech Soft 3D. “This acquisition not only makes Tech Soft 3D a one-stop shop for the most comprehensive set of CAD data translation and publishing solutions, and is also in line with our vision of helping users, developers and enterprises leverage the full value of their 3D data.”

The Tech Soft 3D organization will continue to be focused on providing core intellectual property to developers, while the Theorem team will continue to focus on delivering products directly to industrial end-users.

Mark Stowe, CEO of Theorem, added, “Over the years, Theorem has built products on top of certain core component technologies from Tech Soft 3D, so we know the teams are compatible and our technologies complementary. We also know that we share a vision of how to extend the value of 3D data for manufacturing enterprises and their supply chains. We’re extremely excited about what we can achieve together.”

Tech Soft 3D intends to continue to maintain and support Theorem’s existing customers that are using its CADTranslate, CADPublish and TheoremXR offerings. Details of the acquisition are not disclosed. Tech Soft 3D is backed by global, technology-focused investment firm Battery Ventures.
