What’s happening at three91 right now.
Less prep work, more focus.
three91 clears away the prep work — so your attention goes where the money is: your customers and your production.
A fabrication shop earns its money by getting customer orders through production fast — not by retyping, estimating and tidying up drawings. That prep work is what we take off your hands. So you can do what counts.
A great deal of time disappears long before the machine starts cutting — in the paperwork ahead of it: sifting through enquiries, opening drawings, retyping dimensions, guessing at prices, repairing old CAD files.
We solve that two ways: fully automatic where that works — and as a managed service where experience is needed. So your attention goes to your customers and your production, not to the prep work.
Two products, one promise: they take off your hands the work that keeps you from your core. One fully automatic, the other as a service.
three91:quote reads enquiries and their CAD attachments on its own, maps every position back to its sources and calculates a finished quote — exactly where scattered information slows other systems down.
The enquiry and its attachments land in the inbox.
Email, DXF, STEP, PDF — geometry, material and quantity are all recognised.
AI groups the data that belongs together and shows it for review.
A priced PDF — checkable, traceable, ready to send.
Hours of manual work become minutes — email in, quote out.
Time for sales and production, not for retyping and re-measuring.
Geometry straight from the drawing — traceable back to the source file.
Your quote is out before the competition has opened the email.
Prepared by a CAD team with 30,000+ datasets delivered.
Paper drawings, multi-part DXFs, broken geometry, unusual formats.
Experienced CAD engineers separate, repair and convert them into production-ready 3D data — through about the simplest workflow imaginable.
DXF · DWG · PDF · STEP · 3D. Review, approve, bill — for you or for your customers.
We are building towards steel fabrication in which every document is understood, priced and ready for production the moment it arrives. From document to part — automatically.
three91 stands for Freie-Vogel-Straße 391 in Dortmund — our home. The street name means free bird, which is where both our name and the swallow come from: fast, precise, unwavering.
That is exactly how software for manufacturing ought to feel. Not ponderous and generic, but quick, exact and thoroughly at home in the steel trade — built by people who understand drawings, cutting processes and production.
Whether it is estimating with Quote or CAD preparation with Shape — show us your bottleneck and we will show you the path from document to part.
