Your know-how lives in people's heads
Design standards, fixturing rules, and "how we always do it" live with a few senior engineers. Every new part pays that tax again.

The agent designs inside your CAD
A plug-in that lives in your CAD system. It reads the model, applies your standards and saved workflows, and makes the change, one undo step at a time.
- Runs in SOLIDWORKS today
- Uses your tools, templates, and rules
- Engineers approve every change
Why now
Engineering teams spend most of their time on work they have done before. AI agents can now drive CAD through its full API, and simulations can run faster than real time. Together they can do that work and check it before anything reaches the floor.
Validation happens too late
Problems show up at first article, at the machine, or in the field. By then a design change costs scrap, machine time, and a week.
Generic AI doesn't know your shop
Off-the-shelf copilots don't know your machines, materials, tolerances, or customers. Suggestions that ignore them are a liability.
How it works
One loop. Three steps. As many runs as it takes.
Automated design, validated in a simulation of your process. Each pass costs minutes of compute, not a week of shop time.

Unify3D Agent · CAD plug-in
The agent designs inside your CAD
Unify3D Agent is a plug-in that lives inside your CAD system. Ask it in plain language, click one of your ribbon tools, or launch a saved workflow. It reads the model, applies your rules, and makes the change through the full CAD API.
- Your standards, templates, and best engineers' methods, built in as tools and workflows
- "Watch me": record an expert once, then turn it into a reusable tool
- Ask, auto, or read-only modes, and every change is a single undo step

The agent designs the simulation
Next the agent sets up the test. With Unify3D Sims it assembles a Simulation App for exactly this part and process: the machine it will run on, that machine's controller and post, the stock, the fixture, and the pass/fail rules your engineers wrote.
- Reusable Simulation Units: kinematics, NC, material removal, tooling
- Profiles describe your specific machines, controls, and materials
- The same setup every time, so results compare run to run

Any process · headless · fast
The design is tested in simulation
The design runs through a simulation of your actual process, headless and as fast as the hardware allows. CNC milling is just our first example: a simulation can be built for whatever decides whether your design is good. Every run is measured against your rules and recorded.
- Built for any process: machining, molding, forming, assembly, robotics, fluids
- Checked against your rules: collisions, loads, cycle time, tolerances, cost
- Snapshots and video for every run

Then it repeats
Results go back to the agent
The agent reads the results the way an engineer would: what failed, by how much, and why. It revises the design and runs the loop again, iteration after iteration while your team works on something else. It stops when the design passes or needs a human decision.
- Concrete feedback: margins, failures, and evidence
- Your engineers approve what ships
- Every loop you build becomes the foundation for the next

We build custom design agents, tools, and workflows on top of the CAD your team already uses. They encode your standards and your best engineers' methods so that every part follows them.
Unify3DUnify3D Agent for SOLIDWORKS
Our first platform. A design agent that lives in the Task Pane, works through the full SOLIDWORKS API, and checks exact API signatures for your installed version instead of guessing. Engineers stay in control: changes can require approval, run automatically, or be limited to read-only, and each one is a single undo step.

Ask Unify3D about this model…
Works inside your CAD
A chat panel, a Unify3D ribbon tab, and right-click "Ask Unify3D" on faces, edges, and features. The agent reads and changes the model through the full CAD API.
Your tools on the ribbon
Quick commands with native input pages, live holographic previews, and verified macros. Each run is one undo step, and every tool can go on a hotkey.
Saved workflows
Larger procedures, such as building a compression mold, saved once and run by the agent the same way every time.
"Watch me" capture
Record an expert doing the job: every feature, parameter, and selection. Then say "turn what I just did into a tool."
Reads any model you hand it
STEP, IGES, Parasolid, native parts and assemblies, STL, 3MF, and OBJ, measured and rendered in the background so the agent sees what you see.
History lives in the file
Design conversations are saved inside the part or assembly and survive renames, copies, Pack and Go, and PDM check-in.
Custom integrations
Agents are most useful when they can reach the rest of your process. We connect them to the systems around your CAD.

Unify3D Sims
Simulations of your process, built for agents to run.
Each Simulation App is a set of Simulation Units behind a stable API, configured by profiles that describe your equipment. Agents run it from the command line at full speed. People watch it in a game-like 3D view.
Example simulation
In developmentA full CNC machine, simulated in real time.
This is one Simulation App, and one of the most demanding: a physics-based 3-axis machining center that runs real NC programs and models material removal, tool loads, collisions, and cycle time, in real time or faster. Its front end, dreamCAM, is an interactive machine in Unreal Engine that you can walk up to and run.
- Prove out programs before they reach the machine
- Check fixtures, holders, and reach on every design iteration
- Train operators on a machine that can't crash
A manufacturing simulation like this can be built for your process.
Your machines, cells, and lines, with the physics and rules that matter to your parts.

Kinematics & tool changer

Agent-built, not hand-coded
AI agents assemble new simulation apps from templates and reusable units, so a sim of your process is a project, not a multi-year software effort.
Profiles make it yours
Swap a profile to model a different milling machine, controller, or post processor. A whole-company profile captures your entire floor.
Fast or accurate, as needed
Some apps run in real time or faster, like CNC milling. Others are slow and precise, like injection molding. Each is tuned to the decision it supports.
Business-specific
For your exact process. Only yours.
A generic copilot can help anyone a little. A loop built around your parts, machines, and rules can take on real engineering work.
Built for one business: yours
Every agent, tool, workflow, and sim profile is developed around your exact process. Nothing about it is generic, and it is not shared with anyone else.
Your IP stays yours
It runs on your workstations and your own AI account. Design history is stored in your files, and your standards never become someone else's training data.
Grounded in your real floor
We started out building factory digital twins with AI vision and sensors. That work now calibrates sim profiles against real machine data, so simulation results match what your shop actually does.
Where it's going
The Unify3D Engine
Today, design and simulation are separate programs with separate data. Unify3D is building toward one model in which precise NURBS geometry, mesh and voxel physics, materials, and soft bodies, liquids, and gases are all native. The design you edit would then be the same thing you simulate, so each pass around the loop gets faster and more faithful.

How we work
Start with one loop.
DFactory was founded by a machinist, so we start from the shop floor and work back to the CAD. We build alongside your team, on-site where it helps, and every loop we build becomes the foundation for the next.
- 01
Pick one process
Find a design task your team repeats every week and a validation step that comes too late or costs too much.
- 02
Codify it
Turn your standards and your best engineer's method into Unify3D tools and workflows inside your CAD.
- 03
Simulate it
Build the sim profile for the machines, materials, and acceptance rules that decide whether that design is good.
- 04
Close the loop
Run design and validation together, measure hours and iterations saved, then decide what to automate next.
One process. One design agent. One simulation. Measurable results.
