AI-native CAD · DraftFlow + Euclid

CAD without the CAD degree.

For forty years, parametric tools asked you to think like the software — months of training, a five-figure seat, and a feature tree that shatters when you touch it. We flipped it. Describe what you want; DraftFlow draws it and Euclid models it — as real, editable geometry you actually own.

W = wall_t × 12 H ⟂ // prompt → editable feature tree W′ — solved, no rebuild error // one parameter changes — the whole model resolves

Drawing generation

Turn a model — or a sketch, or a sentence — into a fully dimensioned, annotated drawing set. Views, sections, callouts, and a title block that follows your conventions.

  • Intent-driven views & auto-sectioning
  • Dimensioning that follows ASME / ISO practice
  • Revision-aware: edits propagate, not redrawn
  • Exports to your native drawing format
02 · Euclid

Parametric modeling

Describe the part. Euclid builds it as a real feature tree — constraints, references, and parameter links intact — so one edit resolves the whole model instead of breaking it.

  • Natural-language & sketch-to-feature modeling
  • Constraint-solving that prevents rebuild errors
  • Editable history — not frozen mesh you can't change
  • Outputs print-ready & manufacturable files

Built for the people old CAD priced out

Heavyweight CAD is overkill for most of the work that actually needs a model or a drawing. If you know what you want but don't want to become a CAD operator to get it, this is for you. The enemy isn't the old software — it's time-to-first-usable-output and the cost of every iteration.

Ecommerce / Amazon sellers Euclid

Ship a product before you've tooled it

You need a manufacturable model for the factory, accurate dimensions for the listing, and a clean render for the product page — before the thing physically exists.

Was$300–800 per revision to a freelancer, 3-day loop
Now"Make the base 8mm thicker, add a cable channel" — seconds
Mechanical & part designers Euclid

You know the part. Skip the modeling tax.

A bracket, an enclosure, a replacement gear, a printable jig. You have the engineering instinct — you just don't want to fight a feature tree for an hour to express it.

WasSketch → constraint → feature, then rebuild errors on every edit

Concept work without the BIM weight

Massing studies, early layouts, client-facing concept drawings. You're paying for enterprise BIM to do work that's 80% concept. Full construction docs can stay where they are.

WasA heavyweight seat & a week to test three massing options

Plans that win the client and brief the crew

Planting plans, hardscape layouts, a pergola or deck. You're stuck between SketchUp and hand-drawing, and the deliverable is a dimensioned plan a client approves and a contractor builds from.

WasTwo tools and a redraw every time the client moves the patio

From idea to a spec your manufacturer accepts

You've got the concept; you need a model and a spec sheet a factory can quote and build. Both engines, one flow — model in Euclid, document in DraftFlow.

WasFreelancer for the model, someone else for the drawings
NowDescribe it once — get the model and the spec sheet together
Hobbyists & makers Euclid

Describe it. Print it. Done.

A custom mount, a cosplay prop, a tabletop insert, a replacement knob. Tinkercad's too simple; Fusion's a wall. You just want the printable file without the learning curve.

Why the old tools keep breaking

Anyone who's lived in SolidWorks, CATIA, or Creo knows the truth: parametric models break. The logic tree is powerful until a reference moves — then the rebuild cascade begins. Bolting AI onto that doesn't fix it. Learning the geometry does.

Legacy / rule-bound
OnboardingMonths of training before you make anything production-ready.
EditsMove one reference and the tree throws rebuild errors down the chain.

/04 · The person behind it

A lifetime in the kernel, waiting for the right moment.

Rajiv Saxena cut his teeth at SDRC — the company whose geometry work became part of Siemens — back when the solid modeling kernel was still being argued into existence. He learned the hard parts from the inside: how constraints really solve, where feature trees go brittle, why a drawing is its own kind of engineering problem.

For years he watched bright ideas for the industry arrive too early — the geometry was there, but the learning wasn't. The models could be drawn but not understood.

"I always wanted to give something back to this field. With learning-based systems finally mature enough to hold real design intent, this isn't early anymore. It's exactly the moment."

3Deuclid is that contribution: not AI bolted onto a forty-year-old paradigm, but engines built learning-first — by someone who knows precisely where the old ones break, and who they left behind.

Stop fighting the tree. Start stating intent.
