Stop hand-drawing cavities.
Let the processor pack the part.
Cavity treats protective-insert design as what it really is — a packing problem. Give it a part and a carton from your library; it works out the best way to fit them, shapes the protective cushion, and hands a ready-to-use design back to your CAD. Same input, same result, every time.

The problem today
Same part, same carton — two different layouts.
Hand two packaging engineers the same part and the same box, and you get two different cavity layouts — different part counts, different geometry, neither clearly the best. The slowest, least repeatable step in packaging engineering is still done by eye.
Time cost
Designing and checking a cavity by hand can take an engineer days per part — before a single sample is cut.
Capped throughput
Output is limited by how many packaging engineers you have, not by how many parts ship.
Inconsistency
The same inputs produce different layouts depending on who does the work, and when.
Put plainly: give the work a part and a standard box, and get back the best way to pack them plus the finished protective insert — the same answer every time, without tying up an engineer for days.
Built to fit how your team already works
- Works from your existing part models
- Picks from your own carton sizes
- Plugs into your CAD
- Runs inside your own network
- An engine that decides — not just a viewer
- A focused tool, not a platform
How it works
Part in. Protective packaging out.
No CAD expertise needed to follow it. You hand Cavity two things you already have; it does the layout work a packaging engineer would otherwise do by hand — and hands back a finished design.
What you give it
- 1Fits the most parts inIt explores far more arrangements than anyone could by hand, and settles on the tightest way to fit your parts in the box.
- 2Shapes the cushionIt forms the protective foam or pulp insert that cradles every part in place.
- 3Proves they're safeIt checks that no part is squeezed or stressed beyond what it can take.
- 4Hands it back to CADIt returns a finished, editable design to your CAD — ready for production, not just a picture.
What you get
You never see the machinery in the middle — you give it a part and a box, and a finished design comes back.
The difference
We don't just pack the shape. We pack the part.
Most tools treat every part as a rigid block. Real parts aren't. Cavity understands that many parts can give a little — and uses that to interlock them tighter than a rigid layout ever could, while making sure no part is pushed past what it can safely take.
A tighter, safer layout than packing by the outline alone can reach.
Flexible-part aware
It allows a controlled amount of give in parts that can bend, opening up tighter arrangements.
Safe by design
Every layout is checked so no part is ever stressed beyond its limit.
Denser, not riskier
Tighter interlock means more parts per carton — without putting the product at risk.
Why it matters
The packaging step stops being the bottleneck.
Cavity isn't about a faster click. It changes what your packaging function can take on — and what it costs you to ship.
Free your engineers
Your packaging engineers stop hand-drawing layouts and move to the work only people can do. Throughput stops being capped by headcount.
Consistent, defensible designs
One best answer every time — not two layouts from two people. Easy to stand behind in a customer or quality review.
Tighter packs, lower cost
Denser layouts mean fewer cartons, less cushioning, and less air shipped — savings that compound across every order.
Your designs stay in-house
Everything runs inside your own network. Your part models and packaging never leave the building.
