In 2024 the company was acquired by Tech Soft 3D, and its products were integrated into Tech Soft 3D’s SpinFire portfolio. Under Tech Soft 3D, the Theorem Solutions offering continues as SpinFire Convert and SpinFire XR, combining CAD translation, 3D publishing, and XR visualization within a single enterprise framework. SpinFire Convert provides multi-CAD translation and lightweight visualization for PLM-ready outputs and 3D PDFs, while SpinFire XR supports immersive visualization and collaboration across AR, VR, and MR, along with XR data preparation and optimization. The suite maintains a historical focus on reducing CAD data access bottlenecks and improving the flow of 3D data across teams, suppliers, and PLM systems.
