Are our old drawings and CAD files worth anything to AI companies?

Sometimes, for drawings your company made and kept with their revisions and calculations. Contract drawings a contractor builds from are the design team’s under standard AIA terms. As of October 2026, four of the 25 providers Data Licensing Report tracks name CAD or drawings.

What would an AI company do with our drawings?

Learn how real designs were worked out. Polyshares’ AutoCAD guide (checked September 2026) says “Drawing sets record how real buildings, parts and sites were designed, with layers, blocks, dimensions and revisions tied to actual projects”, and that in their project folders “they show how a design moved from early layouts to issued sheets”. Telegraph Lab describes the drive files it takes as “The work itself, including project documents, spreadsheets, designs, and technical files” (as of October 2026).

Protege, a dataset supplier Data Licensing Report lists under other channels, offers model builders construction and engineering data, blueprints included. AEC Magazine reported in October 2024 that Autodesk’s senior director of AI research, Tonya Custis, said “It’s very hard to get data at scale that very explicitly ties inputs to outputs”.

Which drawings are worth more, and which less?

Drawings that keep their history and their project context count for more.

• Revisions and the work behind them. Telegraph Lab’s $450K engineering-firm card lists “CAD drawings, calculations, technical reports, revisions, and project specifications”. Two common exports drop older versions. Procore’s data extracts include “only the current revision of items” unless you choose all of them, and Autodesk’s As-built Export takes current file and sheet versions.
• The whole project folder. Polyshares asks sellers to report a folder size that includes “DWG, DXF, external references and sheet sets” and says to “export whole project folders rather than single files”, so references between files still resolve.
• Links to the job record. Polyshares’ Procore guide describes punch lists “tied to drawings” alongside RFIs and submittals, records the construction page covers.

Sets your company did not author count for less (below). So do blocks and details downloaded from manufacturers’ sites, which may carry the publisher’s terms.

Which buyers say they want drawings or CAD files?

Four, as of October 2026. Data Licensing Report counts a provider when its own pages name drawings, CAD files or CAD software such as AutoCAD, and checks all 25 it tracks the same way, Telegraph Lab included.

Provider	What it is	What its own pages name
FileYield	Listing site; buys nothing itself	“CAD files” in its manufacturing category (source)
Handshake AI	Licenses directly	AutoCAD, beside Figma, among example sources (source)
Polyshares	Licenses directly	“Design files, drawings and creative assets”, with export guides for AutoCAD and Procore
Telegraph Lab (affiliated)	Licenses directly	CAD among drive file formats, and an engineering firm’s “CAD drawings” in a deal card (source)

None names Revit, BIM or IFC models. Others use wider words that may or may not include drawings: Mercor lists “spec sheets” and “project files”, Replay lists “diagrams, docs, and designs”, License My Data names “GitHub, GitLab and design tools”, and SimpleClosure’s AssetHub counts “designs” in workspace data. Troveo and SimpleClosure name Figma, which holds screen and product designs rather than drawings. No other provider names drawings, CAD files or CAD software (checked October 2026).

Who owns the copyright in a drawing?

By default, the person who drew it or their employer; a signed agreement can move it. Federal law protects “architectural works” (17 U.S.C. §102(a)(8)), a building’s design “as embodied in any tangible medium of expression, including a building, architectural plans, or drawings”. Engineering drawings are graphic works, which include “technical drawings, including architectural plans”.

• Staff. The Copyright Office’s Circular 41 (revised March 2021) says the designer is the author “unless the work is a work made for hire”, and then the employer is. Work an employee prepares within the job is made for hire under §101.
• Freelance drafters and outside consultants. Commissioned work is made for hire only if it fits one of nine listed categories and both sides sign an agreement saying so; the list does not name drawings or architectural works (§101). Otherwise ownership moves only by a signed written transfer (§204(a)), so look for an assignment clause.

Your own lawyer can tell you whether a given set is yours to license.

What do AIA and ConsensusDocs contracts say about drawings?

Under the AIA forms, the architect and its consulting engineers keep the copyright and others get a license tied to the project.

• Owner and architect (B101-2017). Section 7.2 of the AIA’s published sample makes the architect and its consultants the authors and owners of their drawings and specifications, copyrights included. Under §7.3 the owner gets a “nonexclusive license to use the Architect’s Instruments of Service solely and exclusively for purposes of constructing, using, maintaining, altering and adding to the Project”, if it performs the agreement and pays.
• Owner and contractor (A201-2017). The contractor’s limits are on the construction page. Shop drawings are prepared “by the Contractor or a Subcontractor, Sub-subcontractor, manufacturer, supplier, or distributor” (§3.12.1), while instruments of service are the work of “the Architect and the Architect’s consultants” (§1.1.7). How much of the design a shop drawing copies is a question for your lawyer.
• As-builts. The marked-up record set is “delivered to the Architect for submittal to the Owner upon completion of the Work” (§3.11); your markups sit on the architect’s sheets.
• ConsensusDocs. Slides from an undated ConsensusDocs webinar summarize its 240 owner-designer form as giving the owner the drawings, but not the copyrights, on final payment, with an option to acquire copyright interest for a stated fee (Art. 10.1 and 10.1.1). A Construction Owners Association of America comment in ConsensusDocs’ 2016 guidebook to the 200 owner-contractor form notes “The design professional’s contract may be written to the effect that the Owner owns the final delivered construction documents”.

Owners’ forms and engineers’ agreements differ; for a design firm, each client agreement decides whether the client took the copyright.

What about drawings a client or GC gave us, or secure buildings?

Treat them as the sender’s until a contract says otherwise. In B101 the architect and the owner each warrant that the sending party owns the copyright in what it sends or “has permission from the copyright owner to transmit such information for its use on the Project” (§7.1). The warranty also covers “any other information”, so existing-building plans and surveys an owner sends fall under it.

• Marked confidential. Under B101 §10.8, information “specifically designated as ‘confidential’ or ‘business proprietary’” must be kept strictly confidential, and the section survives the agreement’s end.
• GC and subcontract clauses. What to read in each is on the legal page.
• Secure buildings. GSA treats qualifying federal building information as Controlled Unclassified Information (construction). Give any sheet with a security or distribution marking the same review.
• Customers’ part drawings, with ITAR and EAR controls, are on the manufacturing page; roof plans and aerial reports on the roofing page.

What else is inside a drawing file?

AutoCAD 2026’s drawing properties show “the name of the last person who modified the file”, taken from the login name. Title blocks name the client, site and designers, and a residential set shows a client’s home. Ask any provider in writing how it treats title blocks and file properties (what “anonymized” means). The sample tool reads none of this; its dates are file-system dates, which copying can change.

Where do our drawings live, and how far back do they go?

Usually in several places at once. Polyshares says DWG files sit “usually on file servers, shared drives or in Autodesk Docs”. As of October 2026:

Where	What it keeps	Getting them out
File server or shared drive	Everything, until someone deletes it	Copy whole project folders, structure intact (Polyshares)
Autodesk Docs	Deleted items stay “as long as there is a valid, active subscription”	Folders download as a ZIP (Autodesk); As-built Export (Forma Build projects) takes up to 15,000 files, can add RVT and DWG models, and its download link expires after six months (Autodesk)
Procore	Each drawing’s revisions, by project	Data extracts take the current revision unless you pick Include All (Procore); the drawing log exports to CSV with revisions and dates (Procore)
Bluebeam Studio	Sessions archived after 90 idle days, deleted at 180, unrecoverable at 300; finished Sessions deleted after 120 (Bluebeam)	The host downloads Session files; the Markups List saves author, date and status as CSV (Bluebeam)
SharePoint, OneDrive, Google Drive	Each system’s schedule	See documents

Older sets may be on paper, a retired server or a backup drive (old systems).

Is Autodesk already using our files to train AI?

For some of its own features. Autodesk said on August 17, 2026 that “For certain AI features, training datasets include elements of customer content in aggregated and de-identified form”, limited to common elements, industry standards or other non-sensitive information, and that it does “not share customer data with third parties for their own model training”. That is product improvement under Autodesk’s terms, separate from licensing your records for a fee (software vendors).

What could our drawings be worth?

One published figure names them. Telegraph Lab, which is affiliated with Data Licensing Report, shows $450K “Paid to the business” for “A 70-person engineering firm” with the CAD record described above. The card is undated, names no company and is Telegraph’s own statement, not a typical amount.

No tracked provider prices drawings by the sheet, the file or the gigabyte, as of October 2026. Published ranges for a company’s whole record are gathered in How much is my company’s data worth?
