AI ASSISTANT FOR AUTODESK INVENTOR
Edit your Inventor model in plain language.
Describe the change. Drafton plans it, shows you a preview diff, applies it transactionally to your live model, verifies the result — and rolls back automatically if anything’s off.
Bring your own Anthropic key — your geometry never touches our servers.
Add 4× M6 clearance holes on the top face, 8 mm from each edge.
- 1 Select face · Top (Face12)
- 2 Sketch 4 points · 8 mm edge offset
- 3 Hole · ⌀6.6 clearance · through-all
- tier: additive — new geometry, reversible
Runs on your machine
A native Inventor add-in — not a cloud upload.
Your key, your data path
BYOK: model calls go straight to Anthropic.
Every change checkpointed
Transactional apply with .bak snapshots.
Auto-rollback on failure
A bad edit undoes itself — verified, not hoped.
How it works
Trust-first by construction. Nothing changes without your OK.
The hard part of “AI that edits your CAD model” isn’t the AI — it’s making it safe. Drafton wraps every edit in a plan → confirm → apply → verify loop.
Say what you want
A natural-language request in an always-on-top side panel — no menu hunting.
See the plan, tiered
Each action is graded safe, additive, restructuring, or generative — you know the blast radius.
Read the diff first
Feature and mass deltas before a single edit touches the model.
Transactional apply
One atomic transaction, a .bak checkpoint written first — fully reversible.
Verify or roll back
A post-apply health check confirms the model — or auto-rolls-back to the checkpoint.
The real model
It edits real geometry — not a chat about it.
Drafton reads and writes your live Inventor document: features, parameters, faces, holes. The plate beside you is the kind of part it works on every day — drag to take a look.
- holes & bores
- fillets & chamfers
- patterns
- parameters
- sketches
- extrudes
What you get
The safety engineering most add-ins never build.
Plan → confirm → apply
Drafton never edits silently. You approve a concrete plan before anything runs.
Transactional + .bak
Every change is one atomic transaction with a checkpoint written first — reversible by design.
Automatic rollback
If a post-apply health check fails, the edit undoes itself back to the checkpoint. Verified, not hoped.
Live model context
Reads your active document — features, parameters, geometry — so requests land in context, not a vacuum.
Change-preview diffs
See feature counts, mass, and added geometry change before you commit — like a code review for your part.
Bring your own key
Your Anthropic key, your cost control, no lock-in. Model calls go direct — we sell software, not inference.
Pricing
A software license. You bring the key.
Drafton sells the software, not the inference — so there’s no token markup and no surprise usage bill. Inventor is ~$2.8k/seat/year; a tool that saves hours a week pays for itself fast.
- 14-day free trial — prove the value before you pay
- Offline grace period so a flaky connection never locks you out
- Direct, BYOK billing — no per-token markup
- Auto-updating: fixes and new capability ship to you
