Prompt
Describe a part, product idea, or mechanism directly in the browser.
MANAGED CAD SANDBOX · HOSTED AI AGENT · OPEN-SOURCE DESKTOP
AI CAD agent in the browser
Try ideas in the browser without installing a CAD environment. When a model becomes a real project, move to the open-source desktop app for local files and deeper control.
Agent Workflow
Prompt, run, preview, iterate
Web focuses on rapid validation and managed execution: less setup, faster feedback, same editable CAD code.
Agent
The hosted agent writes editable CAD code instead of producing a one-shot mesh.
Sandbox
Forgent3D runs the CAD code in a prepared browser environment.
Preview
Inspect the 3D result, then let the agent revise against errors, geometry, and feedback.
Demo
Agent-generated CAD, not one-shot images
The same core loop works across Web and Desktop: generate code, build real geometry, inspect the result, and keep iterating.
01
Describe the model
A natural-language prompt starts the modeling loop without turning the result into a disposable image.
02
Agent plans editable parts
The agent breaks the request into concrete CAD steps that can be reviewed and revised.
03
Generate real geometry
Model code becomes inspectable 3D geometry: parts, frames, holes, mounts, and constraints.
04
Preview and revise
Use the preview, dimensions, build status, and screenshots to guide the next agent revision.
Why Web?
Web is the hosted agent service
The desktop app can be more complete and open source; Web is valuable because it removes setup, dependency management, and agent orchestration work.
Models
No CAD Setup
Run Python CAD generation without installing kernels, build tooling, or local project scaffolding first.
Agents
Hosted Agent Loop
The browser product packages prompt, code generation, execution, preview, and revision into one guided flow.
Local
Open-Source Desktop
Use the full local workbench when you need private files, deeper control, or integration with Codex, Claude Code, and Cursor.
Product Paths
Web validates fast. Desktop gives full local control.
They do not need to compete: Web is for quick exploration and hosted execution; Desktop gives advanced users complete local control.
Hosted agent
Forgent3D Web
- CAD dependencies ready to run in the browser
- Built-in agent flow for prompt, code, build, preview, and revision
- Best for quick trials, demos, teaching, sharing, and zero-setup exploration
Open-source local workbench
Forgent3D Desktop
- Full local app for advanced projects and private files
- Works with Codex, Claude Code, Cursor, and your own project structure
- Best for deeper engineering workflows, local control, and open-source trust
Both paths keep the important promise: editable CAD code and real 3D preview, not disposable images.
