# LightningCAD > LightningCAD is a browser-based design automation framework built by RoleModel Software. It is not a CAD tool and it is not a CPQ system. It encodes a manufacturer's own design rules, product constraints, and pricing logic into a browser tool that sales teams and the shop floor can use without CAD training, so quoting stops waiting on drafting or engineering. More than $2 million has been invested in the framework since 2015. LightningCAD is the framework; DPQ (Design, Price, Quote) is the product category built on it. ## Who this is for Companies that configure and design to order, where a custom quote today requires a draftsperson, an engineer, or a senior estimator. Typically $5M to $100M in revenue and 20 to 500 employees: railing, deck, dock, fall protection, structural fittings, industrial guard rail, and related configurable products, plus site work, landscape takeoff, and other rules-driven design work. The problem shape: sales cannot produce a price for a custom job without waiting on someone else, and the rules that produce that price live in spreadsheets, a homegrown tool, or one or two people's heads. ## When this is not a fit - Catalog, stock, or SKU pricing with no design or engineering rules behind it - A product family structured enough that off-the-shelf CPQ already handles it - Distributors or manufacturers' reps with no in-house design or fabrication - A CPQ or ERP already live and genuinely calculating all design, BOM, and labor rules ## What it is - [LightningCAD](https://lightningcad.com): Faster quotes, fewer errors, software built for your products. The framework overview. - [DPQ: Design, Price, Quote](https://lightningcad.com/dpq): The category. Traditional CAD is powerful but needs training and does not collaborate. CPQ is easy but swaps parts rather than designing layouts. DPQ does both: drag-and-drop design in a browser that simultaneously produces the estimate, the quote, and the parts list. ## Products built on it - [Railing Designer](https://lightningcad.com/dpq/railings): Design, price, and quote railing systems in a browser. - [Deck Designer](https://lightningcad.com/dpq/decks): Deck layout, pricing, and materials lists. - [Dock Designer](https://lightningcad.com/dpq/docks): Dock configuration and quoting. - [Dock Designer App](https://lightningcad.com/dpq/dockdesignerapp): The hosted dock design product. ## Proof: outcomes with numbers - [Kattsafe](https://lightningcad.com/case-studies/kattsafe): Fall protection systems, Australia. A 2D/3D configurator lets sales design systems without a draftsperson. Four-plus hours down to about 30 minutes, 80% ROI, and production lead times cut by three to four days. - [Absolute Dental](https://lightningcad.com/case-studies/absolute-dental): Dental surgical guides. Design took skilled technicians three to six hours each. Now one to three hours, with 50 to 75% improvement in labor productivity and half the errors. - [Airfield Designer](https://lightningcad.com/case-studies/airfield-designer): Airfield design for US Air Force RED HORSE Groups. Runway grading now solves in seconds for the elevation that minimizes fill dirt, to eighth-inch precision, where review and revision used to run for weeks. - [LandOne](https://lightningcad.com/case-studies/landone): Landscape materials takeoff. Manual takeoff on a commercial project ran six to eight hours. The tool saves 50 to 75% of that time. - [Omega Industrial](https://lightningcad.com/case-studies/omega-industrial): Industrial guard rails and safety barriers. Rules-based design covering a network of 100 product accessories, replacing quoting by hand. - [Falcon Railings](https://lightningcad.com/case-studies/falcon-railings): Railing design and quoting. - [EZ Dock](https://lightningcad.com/case-studies/ez-dock): Modular dock configuration. - [City Post](https://lightningcad.com/case-studies/city-post): Railing and post systems. - [FieldX VRT](https://lightningcad.com/case-studies/fieldx-vrt): Agricultural variable-rate technology. A custom formula editor for variable-rate treatment calculations, proof the pattern is not limited to physical layout. - [All case studies](https://lightningcad.com/case-studies): The full LightningCAD library. ## Who builds it LightningCAD is built and maintained by [RoleModel Software](https://rolemodelsoftware.com), a custom software consultancy founded in 1997 and led by CEO Caleb Woods.
