## agentcad

agentcad tackles a specific problem: AI agents write plausible-looking CAD scripts that produce bad geometry on the first try. Instead of leaving you to babysit the iteration loop, it gives the agent a tight feedback cycle so it converges on printable, valid geometry on its own. You install it with pip inside a Python 3.10–3.12 virtual environment, point your agent at it, and hand over a parametric part description.

The design decisions center on verification. Every run returns machine-readable metrics — dimensions, volume, face and edge counts, and an is_valid flag — alongside PNG renders from any angle. The agent reads both, spots its own errors, and revises before you ever see a broken part. A pre-execution validation layer catches problems before anything runs, an inspection mode produces a topology report for debugging, and version diffs track how a design evolved over iterations.

Integration is deliberately lightweight. Scripts need no boilerplate imports because build123d primitives, show_object, and agentcad edit helpers are pre-injected, so `box = Box(10, 20, 5)` followed by `show_object(box)` just works. Adding it to `.mcp.json` makes it available in Claude Code, Cursor, or Windsurf, and it can run through uvx without a prior install. `agentcad init` also writes a Claude Code skill and an AGENTS.md block into the project so the agent knows the workflow in later sessions. Examples on the site include a 234-part 1903 Wright Flyer reconstruction and single-prompt parts such as a phone stand, a chess rook, and a filleted electronics enclosure — each reporting valid geometry, face and edge counts, and volume.

**Pricing & Plans:** Free and open source. agentcad is Apache-2.0 licensed, installs via pip or uvx, requires no signup, and runs entirely on your own machine.

- **Verified geometry feedback loop:** Every run returns dimensions, volume, face/edge counts, and an is_valid flag plus PNG renders so the agent can iterate until the part is genuinely printable.
- **build123d-native, CadQuery-compatible:** Scripts are written with the build123d API and pre-injected primitives, while CadQuery-compatible workflows are supported for existing projects.
- **Multi-format export:** Produce versioned STEP files for CAD interchange and STL, GLB, or OBJ for 3D printing and web viewers.
- **Validation, inspection, and diffing:** Pre-execution checks catch errors before running, a topology report helps debug geometry issues, and version diffs track design iteration.
- **Zero-boilerplate agent setup:** Add to .mcp.json for Claude Code, Cursor, or Windsurf, run via uvx without installing, and let agentcad init write a skill plus AGENTS.md into the project.

**Strengths:** Free and open source under Apache-2.0 with no signup required; Returns metrics and renders so agents catch bad geometry before you do; Runs locally with a small, zero-boilerplate scripting surface; Works with Claude Code, Cursor, Windsurf, and any MCP-compatible agent via uvx

**Limitations:** Requires Python 3.10–3.12 and comfort with script-based parametric modeling; Best results depend on an agent that can read metrics and iterate; It complements rather than replaces a full GUI CAD application for manual edits

## Fast3D

Fast3D is a generative AI tool focused narrowly on one job: making 3D models fast. Instead of an entire modeling suite, it is a prompt-driven generator where you supply text or an image and receive geometry plus materials ready to download. The homepage positions generation at roughly 10 seconds for simple cases, with heavier, texture-rich models taking longer — the FAQ notes a range of about 5 to 180 seconds depending on settings.

The workflow supports both text-to-3D and image-to-3D. Multi-view image uploads are the recommended path when accuracy matters, since the model can triangulate detail from several angles. On the material side, Fast3D emphasizes high-fidelity PBR texture synthesis with surface detail and seamless tiling, which matters for anyone importing assets into a PBR-based renderer or game engine.

Access is tiered through a credit system rather than a flat subscription feature set. Different mesh densities consume different credit amounts, and PBR texturing multiplies the cost. Free accounts can use the lighter tiers with a monthly cap, while VIP plans unlock every tier. Exports cover the formats most pipelines expect, including GLB/GLTF, FBX, OBJ/MTL, and STL. An API is planned but not yet available, so automated batch generation is not currently an option.

**Pricing & Plans:** Freemium with monthly or yearly paid plans (yearly discounts available) and custom quotes for higher usage. Generation is metered by credits: Fast, Standard, Pro, and Ultra meshes cost roughly 20, 50, 100, and 200 credits, and PBR textures triple the total.

- **Text-to-3D generation:** Type a description and receive a 3D model in roughly 10 seconds, with style customization for simpler control.
- **Image-to-3D generation:** Upload a single image or multiple views to reconstruct geometry with higher accuracy; multi-view input improves precision noticeably.
- **High-fidelity PBR materials:** Generate professional-grade PBR textures with detailed surface structure, seamless tiling, and intelligent style transfer.
- **Multi-format export:** Export as GLB/GLTF, FBX, OBJ/MTL, or STL so assets drop into game engines, 3D printing, AR/VR, and design tools.
- **Mesh density tiers:** Choose Fast, Standard, Pro, or Ultra mesh quality depending on how much geometric detail your project needs.

**Strengths:** Free tier with no login required to try generation; Both text-to-3D and image-to-3D in one interface; PBR texture synthesis and multi-format export for real pipelines; Mesh density tiers let you trade quality against credit cost

**Limitations:** No API access yet, which limits pipeline automation for studios; Quality still depends on clear input images or well-crafted prompts; High-detail models with PBR textures can take up to a few minutes
