AI workspace · hardware engineering

Sketch a part. Ship manufacturable CAD.

Describe changes in plain language. Cassett updates your model and surfaces the right questions — dimensions, materials, and manufacturability.

Platform

Cursor for mechanical engineers

Geometry intelligence, conversational edits, and DFM checks in one workspace — built for how hardware teams actually work.

AI understands geometry

Parses topology, identifies features, explains assemblies.

Edit with natural language

Describe the change. Cassett proposes, explains, applies.

Know what you can make

Real-time DFM for CNC, injection molding, SLS, sheet metal.

CAD Intelligence

AI that reads your CAD files

Upload any format. Cassette parses geometry, identifies manufacturing constraints, and explains every part — stress zones, assembly hierarchy, likely process.

Cassett — part analysis

Summary

22mm brushless motor mount. Optimized for lightweight CNC machining from 6061 Al. 4× M3 clearance holes on 28mm bolt circle.

Manufacturing

Primary method3-axis CNC

AlternateSLS Nylon (−40% cost)

Min feature1.8mm wall

Concerns

⚠Stress concentration at inner bolt ring — fillet radius < 0.3mm

✓All tooling paths accessible from 3-axis setup

Cassett — AI Engineering Console

>Reduce weight by 10%

·Pocketing 4 faces of inner plate. −11.3g (−9.8%). Min wall 2.1mm. CNC toolpath clear.

>Prepare for injection molding

·Adding 2° draft angles. Removing undercuts on face C. Min wall: 1.8mm (ABS). Gate: bottom center. 3 issues resolved.

>What material would you recommend?

·For this geometry and load: 6061 Al (CNC, high stiffness), PA12 (SLS, complex form), or POM (IM, wear). Current tooling favors PA12.

Conversational Editing

Tell it what to change

Describe the modification. Cassette interprets intent, proposes geometry changes with tradeoffs, then applies on approval.

Design Version Control

Git for physical designs

Every AI change becomes a diffable, branchable checkpoint. Branch alternatives, compare geometry, restore any revision.

Built for the full engineering workflow

Multi-format

STEP, STL, OBJ, Parasolid, Fusion. Hierarchy preserved.

Engineering memory

Remembers prior decisions, constraints, rejected approaches.

DFM analysis

CNC, injection molding, SLS, FDM, sheet metal — process-specific.

Assembly reasoning

Part relationships, mating constraints, degrees of freedom.

Simulation-ready

FEA mesh export with AI-suggested boundary conditions.

Fast by design

Streaming AI, instant viewport, sub-100ms revision switching.

Engineers ship faster with Cassette

“The AI geometry explanation alone saves hours onboarding new MEs. Cassette just tells them what the part is and how it's made.”

Sr. Mechanical Engineer · Drone propulsion startup

“"Reduce wall thickness by 15%" and I get a DFM check instantly. The old workflow was three tools and half a day.”

Tom Walsh

Hardware Lead · Robotics company

“Git for CAD was a fantasy for years. Cassette made it real. We branch designs, compare geometry diffs, roll back without losing anything.”
