SOLIDWORKS is a powerful platform on its own, but its real strength as a professional tool comes from how well it can be extended. With hundreds of add-ins available – from native Dassault Systèmes products to third-party integrations built by specialist vendors – engineers can tailor the software precisely to their workflow. The challenge is knowing which ones are actually worth using.
This list covers eight add-ins that deliver genuine, practical value across the most common engineering and manufacturing workflows: product data management, CAM programming, design automation, simulation, visualization, design sharing, manufacturing quotes, and design configuration.
1. OpenBOM – BOM Management and Cross-Team Collaboration
For most SOLIDWORKS engineers, the moment a design leaves CAD and needs to be communicated to purchasing, manufacturing, or a contract manufacturer is where the process starts to break down. Excel exports go stale, emailed spreadsheets multiply into conflicting versions, and no one is ever quite sure which BOM is current.
The OpenBOM add-in for SOLIDWORKS solves this by embedding directly into the SOLIDWORKS interface and connecting the design environment to a live, cloud-based product data platform. With a single click, engineers can extract a fully structured Bill of Materials – single-level, multi-level, or flattened – with quantities automatically calculated and high-resolution part thumbnails included. Alongside the BOM, a parts catalog is created in OpenBOM to store business data that does not belong in the CAD file itself: supplier names, manufacturer part numbers, unit costs, and lead times.
What makes the integration particularly useful in practice is its bidirectional nature. Data flows from SOLIDWORKS into OpenBOM, but values added by purchasing or production teams – a machine center assignment, an updated cost, a supplier note – can be written back into the original SOLIDWORKS files. Derivative files (PDF, STEP, DXF, DWG) are generated and linked automatically, part numbers can be validated before sync to prevent duplicates, and templates save all configuration settings for reuse across projects.
Once data is in OpenBOM, anyone on the team – purchasing managers, production planners, contract manufacturers – can access it in real time through a web browser, with no SOLIDWORKS license required. For small and mid-sized manufacturers in particular, it is one of the most direct paths from CAD to a fully collaborative, connected product data workflow.
Best for: Engineers who need to share BOMs and product data with teams beyond CAD – purchasing, manufacturing, and supply chain.
2. CAMWorks – Integrated CNC Programming
For teams that take their designs from SOLIDWORKS directly to CNC machining, CAMWorks is the most deeply integrated CAM solution available. As the engine that powers SOLIDWORKS CAM – included in every SOLIDWORKS subscription since 2018 – CAMWorks is embedded directly into the SOLIDWORKS environment, meaning CAD and CAM data live in the same file.
The core advantage is full associativity: when the design changes, toolpaths update automatically. Automatic Feature Recognition (AFR) identifies over 20 types of prismatic features on native SOLIDWORKS models and generates machining operations with minimal manual input. The Technology Database (TechDB) stores company-specific machining best practices so that programming knowledge is captured and reusable, rather than locked inside the heads of individual programmers.
For teams that need more than the standard SOLIDWORKS CAM tier, CAMWorks adds advanced 3-axis operations, 4- and 5-axis simultaneous milling, mill-turn capabilities, and virtual machine simulation that runs directly from the actual G-code used on the CNC machine – eliminating dry runs and reducing setup time significantly.
Best for: Machine shops and manufacturers who want to move from design to CNC programming without leaving SOLIDWORKS or managing separate CAD and CAM files.
3. SOLIDWORKS Simulation – FEA and Structural Analysis
SOLIDWORKS Simulation is the native finite element analysis (FEA) suite built directly into the SOLIDWORKS ecosystem. It allows engineers to test designs under real-world loading conditions – stress, strain, fatigue, vibration, thermal loads, and more – without exporting geometry to a separate analysis tool.
The tight integration with the CAD model means that as geometry changes, simulations can be updated and rerun without rebuilding the setup from scratch. For common design validation tasks, this dramatically shortens the feedback loop between design and analysis. SimulationXpress, the entry-level version included with all SOLIDWORKS licenses, covers basic static stress analysis on parts. The full SOLIDWORKS Simulation package adds assembly analysis, dynamic studies, fatigue analysis, and nonlinear capabilities for more demanding applications.
For engineering teams that need to validate structural integrity, identify stress concentrations, or optimize designs for weight and safety before physical prototyping, Simulation provides a well-integrated and widely supported option that works natively with SOLIDWORKS geometry and material data.
Best for: Product designers and structural engineers who need to validate designs under load without leaving the SOLIDWORKS environment.
4. DriveWorks – Design Automation and Configuration
DriveWorks is a design automation platform that integrates with SOLIDWORKS to automate the generation of custom product variants. Rather than manually creating a new 3D model every time a customer requests a slightly different version of a product, DriveWorks allows engineers to define the rules that govern how designs change – dimensions, features, materials, part numbers – and then applies those rules automatically when new specifications are entered.
The result is that a custom product variant – complete with 3D model, 2D drawings, BOM, and documentation – can be generated in minutes rather than hours or days. This is particularly valuable for manufacturers of configurable products such as custom machinery, enclosures, structural components, and modular assemblies, where product variations are frequent but follow predictable patterns.
DriveWorks integrates directly into SOLIDWORKS as an add-in and also offers a standalone configurator that can be embedded in customer-facing sales portals, allowing sales teams or even end customers to configure products and trigger the engineering output automatically.
Best for: Manufacturers of configurable or made-to-order products who need to eliminate repetitive manual design work for product variants.
5. SOLIDWORKS Visualize – Photorealistic Rendering
SOLIDWORKS Visualize turns engineering CAD models into photorealistic images and animations, without requiring any expertise in traditional 3D rendering tools. It is available as a standalone application that imports SOLIDWORKS models directly, and a complimentary seat of SOLIDWORKS Visualize Standard is included with every SOLIDWORKS Professional and Premium license on active subscription.
The key value is speed. With drag-and-drop materials, intelligent lighting setups, and GPU-accelerated rendering, Visualize allows marketing teams, product managers, or engineers to produce presentation-quality visuals from a SOLIDWORKS model in a fraction of the time that traditional rendering pipelines require. The Professional tier adds advanced rendering modes, animated turntables, and interactive VR output.
Because Visualize can be installed independently of SOLIDWORKS – on a designer’s or marketer’s machine, for example – it extends the value of CAD data to people who never open SOLIDWORKS itself. Models stay connected to the source geometry, meaning that when the design changes, renders can be updated without rebuilding scenes from scratch.
Best for: Engineering teams that need to produce high-quality product visuals for presentations, marketing, or client approvals directly from CAD data.
6. eDrawings – Lightweight Design Sharing and Review
eDrawings is SOLIDWORKS’s native solution for sharing 3D models and 2D drawings with stakeholders who do not have a SOLIDWORKS license. The free eDrawings Viewer allows anyone to open, rotate, section, and measure SOLIDWORKS files, as well as files from other common CAD formats, without requiring any CAD software installation beyond the viewer itself.
For engineering teams that regularly share designs with customers, suppliers, or internal reviewers who are not CAD users, eDrawings reduces the friction considerably. Instead of exporting STEP files or PDFs – which strip away the 3D interactivity – teams can share native SOLIDWORKS files that recipients can explore fully in 3D. Markup and annotation tools allow reviewers to leave feedback directly on the model or drawing.
The Professional version adds augmented reality and virtual reality viewing on supported devices, as well as the ability to save models as interactive WebHTML files that can be opened in a browser. For design reviews, customer approvals, and supplier communication, eDrawings provides a fast and accessible way to share CAD data without compromising on interactivity.
Best for: Engineering teams that need to share 3D designs with non-CAD users for review, approval, or manufacturing communication.
7. Xometry Add-In – Instant Manufacturing Quotes
The Xometry add-in addresses one of the more time-consuming steps in the early stages of product development: getting manufacturing quotes. Traditionally, this requires exporting geometry, uploading it to a supplier portal, specifying material and process requirements, and waiting for a response. The Xometry add-in eliminates most of this by bringing instant quoting directly into the SOLIDWORKS workspace.
With the add-in active, engineers can select a part, choose a manufacturing process – CNC machining, 3D printing (across eight technologies), sheet metal fabrication, injection molding, and others – specify material and finish, and receive an instant price and lead time without leaving SOLIDWORKS. Design-for-manufacturing (DFM) feedback is also displayed in real time, flagging potential issues with the current geometry before an order is placed.
For teams doing rapid prototyping or evaluating manufacturing options early in the design process, this saves significant time and allows cost and manufacturability to be considered alongside design decisions rather than after them.
Best for: Engineers who need fast manufacturing cost estimates and DFM feedback during the design process, without switching to external quoting platforms.
8. SOLIDWORKS Toolbox – Standard Parts Library
Toolbox is a native SOLIDWORKS add-in included with SOLIDWORKS Professional and Premium that provides a fully integrated library of standard hardware components – fasteners, bearings, structural steel profiles, shafts, and more – based on international standards including ISO, DIN, ANSI, and others.
Rather than modeling standard parts from scratch or hunting for downloaded STEP files of uncertain quality, engineers can drag and drop standard hardware directly into assemblies from within SOLIDWORKS. Toolbox components are parametric – a single bolt model, for example, covers every size in a standard – and they integrate with the SOLIDWORKS BOM so that part numbers and descriptions populate correctly without manual entry.
For mechanical assemblies that include significant volumes of standard hardware, Toolbox reduces modeling time noticeably and improves BOM accuracy, since standard part data comes pre-configured rather than being entered manually. It is also configurable, allowing companies to add their own frequently used standard parts to the library for consistent reuse across projects.
Best for: Mechanical engineers working on assemblies with standard fasteners, hardware, and structural components who want to eliminate manual modeling and ensure consistent BOM data.
Final Thoughts
The right add-ins depend entirely on where your workflow has the most friction. For engineers dealing with the handoff between design and the rest of the business – purchasing, manufacturing, supply chain – OpenBOM is one of the most impactful additions available. For teams moving from design to CNC machining, CAMWorks eliminates the gap between CAD and production. For those presenting designs to clients or validating them structurally, Visualize and Simulation fill needs that the core SOLIDWORKS package addresses only partially.
Most of these add-ins offer free trials or entry-level access, making it practical to test them against real workflows before committing. Start with the one that addresses your most immediate bottleneck – that is usually the one that pays for itself fastest.
