First article inspection, without losing the weekend to ballooning.

Numbering every characteristic on a print and transcribing it into an inspection form is slow, error-prone, and has to be done again every time the drawing revs. Most of that's mechanical. Most of it can come off your plate. The verification can't, and in inspection that's not a small point.

If you're in quality, this is probably the first job you'd hand off. A print arrives, somebody balloons it, numbering every dimension, tolerance, note and finish callout in order. Then every one of those characteristics gets typed into a form, with its nominal, its tolerance and its actual. On a busy print that's most of a day. Then the drawing revs and you do it again.

The work is necessary. Your customer requires it, and on aerospace work the standard is explicit about it. But the necessary part is the verification, and almost none of the afternoon goes to verification. It goes to numbering, transcribing and formatting.

Where the time actually goes

On aerospace work the AS9102 framework structures this into part accountability, the material and process certifications, and the characteristic accountability that ties every ballooned number to a result. Outside aerospace, customers ask for the same three things even when the form doesn't have a name.

What can honestly be automated

The mechanical parts, which is most of the work:

What must not be automated, and I mean this

I would rather lose the sale than be vague here, because this is a regulated activity and the consequences of getting it wrong aren't commercial.

The verification stays with your inspector. Always. Extraction from a drawing is very good and it isn't perfect. A dimension can be ambiguous, a note can be worded unusually, a scanned print can be poor. So the correct design is one where every extracted characteristic is presented to a person to confirm, and the system tells you plainly what it was unsure about instead of quietly guessing. You're buying your way out of the typing, not out of the check.

Anything sold to you as a hands-off first article should worry you. Your name is on the form, your customer is relying on it, and an auditor will ask who verified it. The honest version of this tool makes that person faster and gives them something better to review. It doesn't replace them, and a vendor who implies otherwise hasn't thought about who carries the risk.

How this gets built

It's built around your prints, your customers' formats, and how your quality group actually works. Not a template. Where it reads from and writes to your existing systems, it does that; nothing has to move to a new platform.

It starts with a paid Diagnostic to look at real prints and real forms and establish what extracts cleanly and what doesn't, which is the honest way to find out whether this is worth doing for your particular work. Then a Build quoted up front. I host it and keep it running, with an ongoing care plan by agreement.

From the work
Drawing reading is built, deployed and running

Reading engineering drawings and pulling structured data off them is something I have built and have running, not a capability I'm describing from a brochure. It exists as a working system today, tailored to one manufacturer, which is the model here: shaped to your prints and your customers rather than sold as a shrink-wrapped product.

Common questions

Does this work on scanned or PDF drawings, or do you need the CAD model?

PDFs are the normal case and they work. Quality matters: a clean vector PDF exported from CAD extracts far better than a scan of a fax. Where a print is genuinely poor, the right behavior is to say so and let a person handle it rather than to guess, and that's how it should be set up.

Are you certifying anything?

No. This is a tool that speeds up the preparation of your documentation. The inspection, the verification and the sign-off are yours, and the accountability stays exactly where it already sits.

We only do a few first articles a year. Is it worth it?

Honestly, probably not, and I would tell you that on the call. This earns its keep where prints are complex, revisions are frequent, or the volume of characteristics is high enough that the transcription is a real recurring cost. A handful a year is a manageable afternoon.

Does it integrate with our CMM or quality system?

That depends on what you run and it's one of the things the Diagnostic settles. The characteristic list is the natural hand-off point, and where a system can accept it, feeding it directly beats retyping it.

Contact

Losing afternoons to ballooning and transcription?

Send a print and we can talk about what would come off it cleanly and what wouldn't. First call's free, about 30 minutes, and if the volume doesn't justify the work I'll tell you that.
