We’re taking a different path, building a parsing engine that converts CAD (DWG/DXF) into fully structured JSON with preserved semantics (no ML in the critical path).We also have a separate GIS parser that extracts vector data (features, layers, geometries) independently, Like to know how you handle consistency and reproducibility across runs using models and how you make it affordable, especially at scale. because a…
Dumbcad line barf will not help you with that at all. There already is a format that is plain text and preserves the semantics: IFC. That's what it was made for.

Is this a service / product you plan to offer outwardly? I'd be interested in learning more. Use case: estimation.
Happy to say that yes. We are in final round of polishing. mostly opening in couple of weeks. We are mainly targeting such uses cases where you can add CAD files into RAG or analytics or search pipeline without losing source of truth or geometry. I will definitely post here when we are ready, keep an eye and it will be free during beta, so you can play how much you want with it.

Yep we're constantly improving we're currently above 0.87 for doors we're thinking of adding a params for the ROC curve so that you can decide your own optimal thresholds depend on when false positive true positive rate is acceptable
Oh nice! I spend a good amount of time eyeballing drawings for overlooked details, so even finding most is a handy tool to me as my brain can skip the marked areas

I think given the scale of projects worked on / being estimated (8 to 9 figure projects) -- it's unlikely we'd be willing to test on our real CAD files. Any chance for enterprise hosted solutions that aren't on the cloud?

I had a job as HVAC engineer for the upgraded Oslo Airport back in 2011; started doing HVAC work for 3 weeks the rest was programming trying to make the rest of people more efficient. Made an Excel sheet with a lot of macros to manage all the drawing of the airport. That’s why I switched to programming when I continued to study, and did not want to come back before I got more experience. They even gave me a big desk…
For what it's worth I found Oslo Airport to be one of the best airport experiences I've ever had. 5 stars.

Their first example is counting fixtures

#100I know its been a few days, but have you looked into the new Bluebeam offerings and do you see that as competition for you guys? https://www.bluebeam.com/bluebeam-max/ Their first example is counting fixtures
The reality is people that work in construction (Excluding field work), refers to AI as a scam and compares it to the crypto hype back in 18 .. compares it to crypto in 2018 — all hype, no landing.. seriously they do not like it.
I built this selfishly. Eight months ago I wished I had a programmatic interface to interact with drawings. So I built one.
last point: our customers aren't just doing takeoffs and they aren't just subs or gc's either — they're building tools in the construction tech space and estimation is one use case. The broader opportunity is making all that structured data accessible.
great q!!
Also I didn't see Claude there "ai" tool (a bit weird they are letting the model providers own the entire interface) count any fixtures, and if it did it was probably pulling it from the markup's table which is enabled via their api, which you can technically just slap an llm on top of it. But hey kudos to them - this space is not easy. (https://developers.bluebeam.com/s/studio?language=en_US)
