What 2025-2026 CADEXSOFT does

CADEXSOFT OÜ is an Estonian-headquartered (Tallinn) software company founded by Roman Lygin — a veteran of Matra Datavision, Open CASCADE, and Intel — that develops Manufacturing Toolkit (MTK), a cross-platform CAD SDK for digital manufacturing. MTK provides B-Rep (Boundary Representation) geometry handling, heuristic feature recognition for CNC machining, sheet metal, and injection molding, Design-for-Manufacturing (DFM) analysis (over 25 checks for CNC, ~30 for sheet metal, 15+ for molding), sheet metal unfolding, Ray Marching-based wall thickness analysis, and a hybrid Genetic Algorithm 2D nesting optimizer. The SDK operates on neutral STEP files without dependency on any specific CAD kernel and ships with bindings for C++, C#, Java, Python, and JavaScript/TypeScript, running on Windows, Linux, macOS, and in browsers. Complementary products include MTK Workbench (a desktop testing and visualization application), MTK Web (an embeddable 3D viewer), and MTKConverter for batch CAD processing.

The company sells MTK through a per-developer-per-year, royalty-free subscription model with tiered plans (Start, Plus, Pro, Enterprise), combining self-serve developer evaluation with direct enterprise sales. Customer segments include independent software vendors building quoting, DFM, and Manufacturing-as-a-Service platforms (Hubs, Fractory, Karkhana.io, Partsimony, QuotationFactory, SecturaFab, Weerg, Jiga, CADDi, ProShop, up2parts), internal development teams at manufacturing companies, and specialized manufacturing cost-estimation software firms (Galorath's SEER-3D for aerospace). Operations span Estonia (HQ), the United Arab Emirates (Dubai), and remote team members, with a stated in-house team of 45+ engineers, designers, product people, marketers, sales, and support. The company is privately held and founder-owned, with no disclosed external institutional funding.

Revenue model

1. SDK Licensing (per developer per year): MTK is licensed per developer per year. Customers choose a plan (Start, Plus, Pro, or Enterprise) matching their use case and scale. Each license includes access to all MTK modules in the chosen plan, runtime slots for deployment, developer tools like MTK Workbench, and add-on manufacturing processes. Additional runtime capacity and developer seats can scale with the customer's needs. Royalty-free licensing with no hidden fees.

Core offering

CADEXSOFT develops and licenses Manufacturing Toolkit (MTK), a CAD software development kit (SDK) that enables software vendors and internal development teams to embed manufacturing intelligence into quoting, Design for Manufacturing (DFM), and Manufacturing-as-a-Service (MaaS) platforms. MTK provides B-Rep geometry handling, automatic feature recognition, DFM checks, sheet metal unfolding, 2D nesting, wall thickness analysis, and browser-based 3D visualization, delivered as cross-language APIs (C++, C#, Python, JavaScript) with per-developer annual licensing and royalty-free runtime. The company also maintains the CAD Exchanger SDK for CAD data interoperability and offers turnkey custom development services.

Product overview

CADEXSOFT offers Manufacturing Toolkit (MTK), a unified CAD SDK for digital manufacturing. The core product is Manufacturing Toolkit which provides B-Rep geometry handling, feature recognition across CNC machining/sheet metal/injection molding, DFM analysis, sheet metal unfolding, nesting optimization, and web-based 3D visualization. MTK is delivered with language-specific APIs (C++, C#, Python, JavaScript), the MTK Workbench desktop application for workflow testing, MTKConverter for batch processing, and MTK Web for browser-based visualization. The toolkit supports manufacturing processes including CNC machining (with over 25 DFM checks), sheet metal fabrication (approximately 30 DFM checks), and injection molding (15+ structural checks), plus wall thickness analysis and 2D nesting optimization.

Partnerships

Two partnerships are on record, tiered core and minor.

• Galorath Inc.coreStrategic or Co-development Partner · 15 May 2025CADEXSOFT collaborated with Galorath to co-develop SEER-3D, a graphical application that automatically extracts geometry data (bounding boxes, volumes, surface areas) from 3D STEP files and feeds it into Galorath's SEER-MFG manufacturing cost model engine. The collaboration included iterative development with focus groups, producing a production application that reduced data collection time from hours to seconds. SEER-3D is being adopted by SEER-MFG's aerospace customer base.
• SENER MarineminorImplementation/ SI/ Consulting PartnerSENER Marine uses CAD Exchanger SDK within their FORAN System for shipbuilding CAD data interoperability. CADEXSOFT's custom development team collaborated with SENER Marine to support integration into their complex engineering workflows. SENER Marine's Product Manager described being satisfied with CAD Exchanger as the foundation of their product.

Scale indicators4 records

Expansion highlights7 records

Broad incumbents

• Dassault Systèmes: Dassault owns CATIA, SOLIDWORKS, and 3DEXPERIENCE, including the 3DEXPERIENCE marketplace with DFM/quoting capabilities. Broad incumbent whose potential entry into CAD-neutral SDK distribution is the primary incumbent threat.
• Autodesk: Autodesk Fusion 360 includes DFM checks and CAD intelligence targeted at manufacturing; Autodesk also operates Forma/IForge3D. Broad incumbent positioned upstream/downstream from MTK's pure SDK business model.
• Bricsys (Hexagon): Bricsys (a Hexagon company) provides BricsCAD and BricsCAD Mechanical with DFM-aware features. Broad incumbent in DWG-based CAD, less of an SDK player; competes for the same MaaS/CDM end customer.
• PTC: PTC's Creo, Onshape, and ThingWorx cover CAD, cloud PLM, and IoT for manufacturing. Broad incumbent offering overlapping DFM and manufacturing intelligence but as part of an integrated PLM stack, not a CAD-neutral SDK.
• Siemens Digital Industries Software: Siemens (NX, Solid Edge, Parasolid, Teamcenter) is the dominant CAD/PLM ecosystem with the proprietary Parasolid kernel at its core. Broad incumbent whose CAD-neutral exposure is structurally lower than MTK's.

Direct peers

• Spatial Corporation: Spatial (a division of Dassault Systèmes) provides ACIS Modeler, 3D InterOp, and CGM components - developer SDKs for CAD modeling, data translation, and 3D visualization, competing directly with MTK in the CAD SDK segment.
• ModuleWorks GmbH: ModuleWorks supplies toolpath generation and machining simulation components to CAM software developers worldwide. Direct comparable for CNC-focused components embedded in CAM/CNC quoting platforms.
• Tech Soft 3D: Tech Soft 3D builds HOOPS developer toolkits (HOOPS Exchange, HOOPS Visualize, HOOPS Communicator) for CAD data translation and 3D visualization. Most direct comparable to MTK's CAD SDK positioning for software vendors embedding engineering intelligence.
• MachineWorks Ltd: MachineWorks provides CNC simulation and verification toolkits (WIP) used by CAM software vendors - same buyer (CNC machining software vendors), overlapping use cases on CNC feature recognition and verification.
• Open CASCADE SAS: Open CASCADE provides the open-source OCCT geometry kernel and SDK used widely in CAD/CAM/CAE development. MTK itself builds on geometry kernels in the same lineage; Open CASCADE is the foundational comparable for geometric modeling SDKs.
