Features
MCP server exposing CAD design, render, and export tools to coding agents
Works with Claude Code, Cursor, WindSurf, and other MCP-capable agents
CLI for local script execution and versioned STEP file output
build123d-native with CadQuery compatibility as an optional extra
Pre-execution static validation under 100 ms (syntax, missing show_object, unresolvable imports)
Structured JSON metrics per run on stdout: dimensions, volume, surface_area, face_count, edge_count, is_valid
Four-view PNG preview composite (top, bottom, upper iso, lower iso) per run
Export to STEP, STL, GLB, and OBJ for 3D printing and web viewers
Diff mode compares two versions with side-by-side renders, colored overlay, and overlap score
Parts mode names, colors, and groups assembly pieces so agents and humans can inspect fit
Spec-check mode measures finished geometry against a written JSON checklist
Topology report via `agentcad inspect` for debugging broken geometry
Zero-boilerplate scripts with pre-injected build123d primitives, show_object, and edit helpers
agentcad init installs a Claude Code skill plus an AGENTS.md (or CLAUDE.md) workflow block
Runs locally with no signup — files never leave your machine
LiDAR and non-LiDAR space capture of rooms, buildings and interiors
360 photosphere capture with an in-app 360 image viewer

    Wants agents to iteratively design 3D parts with script validation and spec-check.

  • Forensics Investigator
    Pick: Polycam

    Requires fast, accurate 3D documentation of crime scenes with detailed point clouds.

  • Product Designer
    Pick: Polycam

    Scans physical prototypes for digital review and exports to OBJ/FBX for further editing.

  • Open Source Hobbyist
    Pick: agentcad

    Free, local CAD generation with agent automation; exports STL for 3D printing.

Frequently Asked Questions

agentcad vs Polycam: which should you choose?

Polycam is the best choice for professionals needing photorealistic 3D scans and floor plans from real-world spaces. Agentcad is ideal for AI agents and developers who want to programmatically generate and iterate on 3D parts. Choose Polycam for reality capture; choose agentcad for agent-driven CAD design.

Can Polycam generate CAD-ready floor plans?

Yes, Polycam’s automatic floor plan generation produces measured 2D/3D floor plans that can be exported to DXF for use in CAD software.

Does agentcad require an internet connection?

No, agentcad runs locally, requires no signup, and all processing is on your machine.

Which tool supports drone photogrammetry?

Polycam processes drone-captured photos and video for site surveys; agentcad does not handle aerial imagery.

Can agentcad be used by non-programmers?

Not easily – agentcad is designed for AI agents and developers who write Python scripts with build123d/CadQuery.

Does Polycam work on Android?

Yes, Polycam supports Android ARCore devices (limited LiDAR) but works best on iOS with LiDAR.

What file formats can I get from agentcad?

STEP, STL, GLB, and OBJ. Also supports PNG renders and JSON metrics.

Is Polycam’s free tier useful?

The free tier allows limited exports (watermarked) and lower resolution, suitable for evaluation but not professional use.

Can I integrate agentcad with VS Code?

Agentcad integrates with coding agents like Claude Code, Cursor, and Windsurf via MCP – not directly as a VS Code extension but through MCP.
