What to Do When a Drawing Review Demo Only Uses the Vendor's Sample

Published October 18, 2026•4 min read

Helonic is an AI construction drawing analysis platform for general contractors sitting through an AI drawing review demo that only uses the vendor's sample set. Twenty minutes into an AI drawing review demo, you notice every sheet on screen belongs to the vendor. Nobody has mentioned your set. That is the moment to ask one question, because the answer tells you more than the rest of the hour will.

Direct answer. Ask the vendor, whether it is Helonic or anyone else, to run a set you send and show the results before you talk price. If they agree and name a date, rebook the meeting on your PDF. If they push the run behind weeks of onboarding or a contract, weigh that before you spend another hour.

What is the one question, and when should you ask it?

Ask it in the first ten minutes, not at the end when everyone is tired and polite. Keep it short:

"Can you run this on a set we send you, and walk us through the findings before we talk about pricing?"

Asking early saves the hour. If the answer is yes, the rest of the meeting can be about logistics: which set, how to send it, and who scores it. If the answer is no, you can end politely before the feature tour.

How should you read the vendor's answer?

What they sayWhat it usually meansWhat to do
"Sure, send it over and we'll run it this week."The tool runs on real sets without hand-holding.Rebook within a week. Send a closed-out job.
"We need to configure it for your standards first."Could be fair. Could mean the sample was tuned.Ask what gets configured and how long it takes. Days is fine. Weeks for a demo is a warning.
"The sample shows the same capability."The vendor would rather not run your set.Ask again, plainly. If the answer holds, end the meeting.
"We only run customer sets in a paid pilot."A business choice, not always a red flag.Ask for a small run on 30 to 50 sheets first. If they refuse, weigh that against the pilot price.
"We can't process that file type."You just learned something the sample hid.Write it down. That limit will show up again on every bid.

A vendor who needs a long setup before running any customer set is telling you how the first real bid will go. How long setup should take is covered in how long AI drawing review takes to set up.

Is a sample set ever fine to use?

Yes, for five minutes of orientation. It shows where the upload goes and what a finding looks like. It is also fine when your security review is not done yet and you cannot send a set.

In both cases, the next meeting has to run on yours. Write that down in the follow-up email so nobody forgets it. The full case for running on your own drawings is in why an AI drawing review demo should run on your own set.

What should you send for the rebooked meeting?

  • A closed-out job with every discipline and the spec book, frozen at one revision.
  • Enough sheets to contain cross-discipline conflicts, usually one full building.
  • Nothing confidential that has not cleared IT and the owner's terms.

Keep the RFI log to yourself. It is your answer key. If the vendor sees it, you cannot tell whether a finding came from the drawings or from your own notes.

The file minimum is in what files you need before the first review, and sizing is in how many sheets a fair pilot needs.

What comes after a good meeting on your set?

A scored pilot, using the protocol in how to pilot AI drawing review software. The criteria to judge the product against are in what to look for in an AI construction drawing review platform.

Helonic runs demos on the customer's set and shows each finding at its sheet location. What it reads is on AI document review, and the category background is in AI for construction drawings.

Practitioner insight

“I just ask at the start now. Can you run ours? One vendor said they'd need a month. We didn't take the second call.”

Conversations with preconstruction directors at regional general contractors who screened AI drawing review vendors before running a pilot.

Frequently Asked Questions

What should I ask if the demo only uses the vendor's sample?
Ask whether they can run a set you send and walk you through the findings before you talk about pricing. Ask in the first ten minutes.
Is it a red flag if a vendor will not run our set?
It depends on the reason. Short configuration is fair. A month of onboarding before any customer run, or a flat refusal, tells you how the first real bid will go.
Is a sample set ever fine to use?
For five minutes of orientation, or when your security review is not done yet. The next meeting should run on your own drawings.
Should we send the vendor our RFI log?
No. The RFI log is your answer key. If the vendor sees it, you cannot tell whether a finding came from the drawings or from your notes.
