There is a question that almost never comes up in a 3D configurator demo, and it is the one that decides what you actually bought.
Not what does it cost. Not how long does it take. This one:
On the day we stop paying you, what happens to the models?
Try it on your shortlist. Ask it plainly, in writing, and watch how long the answer takes. In a category where every vendor publishes a page on conversion lift and a page on integrations, this question is conspicuously unaddressed, and that absence is not an oversight.
What you are actually buying
When a manufacturer commissions interactive 3D, it feels like commissioning a photograph or a brochure. You pay, you receive a thing, the thing is yours. That intuition is wrong often enough to be expensive.
Most of this market sells one of three arrangements, and they are not close to equivalent.
A hosted experience. You pay a monthly or annual fee. The platform holds the models, runs the viewer, and serves it to your site through an embed. Your CAD went in at the start; what comes back out at the end, if anything, is a matter of policy rather than contract. Stop paying and the embed stops resolving. Your product page has a hole in it.
A licence to use. You have the files, or can request them, but not the right to run them anywhere else, or not without the vendor proprietary player, which is itself the subscription. The assets are technically yours and practically inert.
Outright ownership. The models, textures, materials and source are delivered to you in open formats. You can host them, hand them to another studio, put them in a trade show kiosk, or do nothing with them for three years and pick them up again. Nobody has to stay in business for your showroom to keep working.
All three get described as “your 3D content” in a sales conversation. Only one survives the vendor relationship ending.
Why this is worse than ordinary software lock-in
Every SaaS tool creates some switching cost. This one is unusual in three ways.
The input was expensive and specific. Getting from engineering CAD to something that runs at sixty frames per second in a browser on a five-year-old laptop is real work: decimation, retopology, baking, material authoring, level-of-detail. That work is where most of the budget goes, and it is not recoverable from the original CAD by pressing a button. Losing it means paying for it again.
It sits on your highest-value pages. A configurator is not an internal tool. It is usually on the product page, in the campaign, in the sales deck, and increasingly in the search result. A dead embed is not an inconvenience; it is a gap on the page you spent the most to get traffic to.
The cost arrives when you have least leverage. You discover the terms at renewal, or during an acquisition, or when the vendor gets acquired, raises prices, sunsets a product line, or pivots. That last one is not hypothetical. One of the better-funded players in this category has repositioned its entire homepage around AI sales agents rather than 3D. Pivots are normal. Depending on someone else roadmap for access to your own product models is a choice.
The economics nobody puts on the pricing page
Published benchmarks from inside the category put a mid-sized implementation somewhere around fifty to a hundred thousand dollars across six to eight months. Assume a five-year horizon and a subscription on top, and you are looking at a number that would fund the work outright two or three times over, while the asset that number produced is still not yours.
That comparison is the one to run before you sign, and it is the one the demo is structured to avoid. It is easier to sell a monthly figure than a five-year total, which is why so much of this market quotes neither.
Four questions, before the contract
Ask them in writing. A vendor who owns their answers will not mind.
1. What files do we receive, and in what formats? “Access to your assets” is not an answer. The answer is a list: geometry, textures, materials, and the interaction source. Open formats such as glTF, USDZ and standard web code mean another studio can pick the work up. A proprietary scene file means only the vendor can.
2. Can we host it ourselves? If the experience can only run on the vendor infrastructure, you have a subscription regardless of what the contract calls it.
3. What happens on termination, and how long do we have? Get the export window in writing. “We would of course help you transition” is a sentiment, not a term.
4. Who owns derivative work? If the vendor optimizes your CAD, who owns the optimized mesh? This is where the genuinely restrictive language usually lives, and it is usually one clause long.
The honest counter-argument
Hosted platforms are not a scam, and there are situations where they are the right call.
If you have five hundred SKUs changing every quarter, a platform with a product-data pipeline and a content team behind it is doing work you do not want to own. If your requirement is a room planner or a furniture visualizer with an established feature set, buying is faster and cheaper than building. If you are testing whether 3D moves the number at all, renting the answer for six months is a sensible experiment, and you should go in knowing it is an experiment rather than an asset.
The mistake is not choosing a subscription. The mistake is choosing one while believing you are buying something permanent, and finding out otherwise at renewal.
What we do, since you will ask
We build interactive 3D showrooms, configurators, digital twins and browser-based AR on fixed scope and a fixed date: three to four weeks for a single product configurator, six to ten for a facility-scale twin. At the end, the models, textures, materials and source are handed over in open formats. There is no subscription that has to stay alive for your showroom to keep working, and if you decide to take the work somewhere else, it goes.
We mention it not because it is clever but because it is unusual, and because the question at the top of this article is the one we get asked least and would most like to be asked more.
Ask it of us too. Ask it of everyone.
