Get paid to license your CAD files and models for AI training
AI companies do pay to license CAD files, mostly through data firms that ask for them by name. Ventra says labs look for CAD libraries specifically, Polyshares lists firms with heavy CAD work as in demand, and Mode lists AutoCAD among its sources. Ventra's own catalog shows 20 of its 31 proprietary datasets as design, drawing or scan data.1,2,3,4
Text and code were online for anyone to train on. Design files never were. A drawing set, a Revit model or a SolidWorks assembly lives on a firm's own server, and Fast Company reported in August 2026 that the drawings and 3D models that could train an architecture model sit in individual firms' servers and filing cabinets. That scarcity is why CAD has become one of the file types AI data buyers now ask for by name.
Ventra says design files and CAD libraries are rare and that labs often want one kind in volume, and its ads list CAD files among the records in highest demand. On a call with us, Ventra said it gets a lot of CAD requests, one of them a lab partner's request for 10,000 building designs; that is Ventra's own account. Mode and Polyshares both list AutoCAD among the systems they take records from, and Nyne has run a Meta ad to engineering firms headed "Your CAD files, paid for."
The firms holding the most CAD are architecture practices with building models and drawing sets, engineering firms with plan sets and calculations, and manufacturers with part models, assemblies and change orders. You don't need to be big, though, because Ventra told us a CAD dataset could even come from one person. A license is a copy, so your team keeps working in the same files the next morning.
Buyers
Who buys CAD data
Each reason is the buyer's own published statement naming CAD or the kind of data it holds.
Featured partners
micro1
Doesn't name CAD on its data partnerships page, so treat it as a fit for the records around your drawings, such as engineering workflows, technical knowledge bases and templates, and not for the drawings themselves. Takes companies with 30+ staff.12,13,14
- $100K to $2M+, micro1 says15
Watch out for: Says it removes personal details only "when relevant", so ask exactly how.16
Ventra
Says CAD libraries are rare and that labs want one kind in volume, and told us CAD datasets don't need its 30-person minimum and could come from one person. It still asks for 3+ years of records, a business in the US, Canada, the UK, Ireland, Australia or New Zealand, and no regulated industry or franchise.1,17,18
- $100K to $2M as potential deals, Ventra says19
- None today, though it may add fees with notice20
- An offer in 3 to 7 days, then paid on net 30 or 6019
Watch out for: Its terms say delivered data may not be deletable.21
Polyshares
Names manufacturing and engineering firms with heavy CAD work, and architecture and construction firms, among the industries in demand now; it takes companies with 50+ staff and 3+ years, and excludes data held for clients.2,22,23,24
- $100K to $2M+, Polyshares says25
- None, Polyshares says26
- An offer in 1 to 2 weeks, then paid in 30 to 60 days27
Watch out for: Exclusive by default, and every deal it lists is exclusive with no end date.28,29
Mode
Lists AutoCAD among the sources it buys, buys an agreed copy directly with no broker fee, and sets the systems and date ranges before anything is exported.3,5,34
Watch out for: The program launched in October 2026 and has no deal record yet.37

What buyers value
What in CAD buyers value
The column on the right lists what to talk through with your buyer before anything is exported.
| Data | Why a buyer values it | Raise with the buyer |
|---|---|---|
| Revit and BIM models | A whole building as linked geometry and data, with walls, rooms, families and schedules that stay consistent across every view. | Consultants' linked models and client-owned projects. |
| AutoCAD drawing sets by phase | One project at schematic design, design development and construction documents, which shows how a design gets resolved. | Title blocks carrying client names, site addresses and seals. |
| SolidWorks, Inventor and Fusion parts and assemblies | Parametric parts with their features, mates and bills of materials, the mechanical design record behind a product. | Customer-owned part designs and anything received under an NDA. |
| Engineering change orders and revision history | Why a part or sheet changed, who approved it and what it replaced, the reasoning a final file leaves out. | Nothing specific |
| Block, family and detail libraries | A firm's own standards drawn once and reused on hundreds of sheets. In our view often the cleanest set to offer, because no client paid for it. | Nothing specific |
| Drawings linked to tests, inspections and RFIs | A drawing tied to its test result, its inspection report or the field question it raised shows what the design did in the real world. | Contractor, supplier and customer names in the linked records. |
| Civil and site plan sets | Grading, utility and site plans with the calculations behind them, a record of how a design answers a real piece of ground. | Survey data supplied by third parties and client site details. |
What does an AI license for CAD files cover?
An AI license for CAD files covers what the written agreement says, and terms differ by buyer, so the useful move is to ask about scope, exclusivity and resale before you sign. Mode says its agreement sets the scope and any exclusivity before export, and Polyshares describes its license as defined material for a defined term.5,6
On scope, ask which projects, folders and years are in, whether the license covers training only or testing as well, and whether a model trained on your files may produce drawings close to yours. On exclusivity, ask whether the deal is exclusive, for how long, and whether you could license the same archive to a second buyer later.
On resale, ask who ends up with a copy, because some firms buy data to resell it and others license it onward. Find out whether the buyer can pass your files to one lab or to many, whether you will be told which labs get them, and what happens to the copies when the term ends.5
What makes a CAD archive worth more?
A CAD archive is worth more when its files are tied together, in our view, because a drawing shows the answer and the linked records show how the team got there. Think of a drawing with the CNC program that cut the part, a design with the emails that shaped it, or a plan with the quote it produced.
Troveo's automotive guide says a drawing linked to its test, production run and warranty claims is worth more than any of those on its own. Polyshares says the value is in reasoning captured while the work happened, not in volume. In Ventra's catalog, 4 of the 31 listings include CNC or other machine files alongside the design files, so keep project folders whole when you count what you have.7,8,9
How many CAD archives are already on offer?
Ventra's public catalog shows 20 design, drawing and scan datasets out of 31, which is the clearest count we have seen from any firm. Those listings show what Ventra is gathering, not what has sold, and none of the 31 shows a price. Rights are the common hold-up, with 14 of the 20 still showing "Being confirmed with the owner".4,10,11

FAQ
CAD data: questions, answered
AI companies do buy CAD files, and some ask for them by name. Ventra says labs look for design files and CAD libraries specifically and names CAD files in its ads, Mode and Polyshares list AutoCAD among the systems they take, and Nyne has advertised to engineering firms for CAD files. Most deals license a copy rather than sell the files outright.1,44,3,23,30
CAD data is in demand because it is scarce. Fast Company reported that the drawings and 3D models that could train an architecture model are not widely available online, and that none of the big AI labs was taking on the problem itself when it wrote. Ventra says labs often want one kind of design file in volume. In our view, a firm with hundreds of projects of one building type, or one family of parts, fits that request well.45,1
Mode's published list names AutoCAD and adds "+1K more", and Polyshares' intake lists AutoCAD under design and CAD; neither names Revit. Ventra lists design and CAD files in general, including mechanical parts and assemblies, and 5 of the 31 listings in its catalog name Revit. Ask each buyer which native formats it takes, and whether it wants RVT and IFC models or exported DWG and PDF sets.3,23,1,46
Ventra lists mechanical parts and assemblies, drawings, specifications, test results and change logs. Cognor Labs, a broker we do not rank, lists CAD and drawings you own, CNC and CAM programs and engineering change orders, and names SolidWorks, Inventor and Fusion on its intake. Troveo's automotive guide says a drawing linked to its test, production run and warranty claims is worth more than any of those alone. Each is that company's own statement.1,47,48,7
No buyer publishes a price for CAD files alone. Ventra's site describes $100K-$2M as potential deals and Mode says $100K-$5M, all for whole companies and as their own figures. Pewter's licensing partner reports a 70-person engineering firm at $450K for CAD drawings, calculations, reports and specifications, a deal Pewter says it did not advise on. On a call, Ventra said company records usually bring about $12,000-$15,000 per employee, and that prices fell about 20% over the past month.19,35,49,50
Troveo's engineering guide lists designs clients own, licensed standards and code text, export-controlled technical data, and anything received under a confidentiality agreement. Polyshares excludes data held on behalf of clients. For most firms the starting point is internal standards and libraries, with names, addresses, seals and part numbers stripped from title blocks and file properties; which client projects can go in is a question to raise with the buyer.51,24
Size depends on the buyer, and CAD has a lower bar than most company records. Ventra told us CAD datasets don't need its 30-person minimum and could come from one person, as long as there are 3+ years of records, the business is in a listed country, and it isn't a franchise or in a regulated industry. micro1 looks for 30+ staff and Nyne for 20+ US W-2 employees, and Polyshares' broker terms ask for 50+ while its public pages set no minimum.17,18,14,31,22,53
