CAD Skills
earthtojake
Open-source library of agent skills for CAD, robotics, fabrication, and simulation — generate STEP/STL, URDF/SRDF/SDF, DXF, and slicer G-code from prompts.
Key features
- Prompt-to-CAD Generation: The CAD skill creates and edits parametric CAD models from natural language or image requests, exporting to STEP, STL, 3MF, and GLB.
- URDF Robot Description: Writes robot structure files with links, joints, limits, inertials, and meshes ready for ROS-based stacks.
- SRDF for MoveIt2: Adds planning groups, end effectors, named poses, and collision rules on top of a URDF for MoveIt2 planning.
- SDF Simulation Worlds: Creates simulator models and worlds with frames, physics, sensors, and lights.
- 2D DXF Drawings: Produces cut-ready DXF profiles, templates, gaskets, and layouts from Python or CAD geometry.
- G-code Slicing: Slices supported mesh files into validated, printer-profiled FDM G-code using real slicer CLIs.
- Bambu Lab Print Jobs: Dry runs, uploads, and cautiously starts local Bambu Lab prints from validated G-code.
- CAD Viewer Previews: Local browser previews for CAD, G-code, URDF, and other robot files for fast agent iteration.
Best for
- Agentic Mechanical Design: Let a coding agent iterate on brackets, flanges, and enclosures directly from natural-language specs.
- Robot Description Authoring: Generate URDF/SRDF/SDF files for new robot arms or mobile bases without hand-writing XML.
- Rapid Prototyping: Take a CAD model to sliced, printer-ready G-code and kick off a Bambu Lab print from within an agent workflow.
- Custom Part Fabrication: Produce DXF/STEP files pre-checked for SendCutSend, then order laser-cut or CNC parts.
- Simulation Setup: Author SDF worlds for physics simulators with the right frames, sensors, and lighting for robotics research.
- Off-the-Shelf Sourcing: Use step.parts to pull ready-made STEP models for common hardware like screws, bearings, and connectors.
Construct Computer
Construct
An AI employee with its own cloud Linux computer that runs workflows, builds internal tools, and finishes scheduled work for small teams.
Key features
- Dedicated Cloud Computer: Each user's agent gets a real Linux cloud desktop, so it can run software and produce files rather than only generating text.
- Reusable Workflows: Encode a process once as agent steps, connected apps, and notifications, then version, schedule, and let any teammate re-run it.
- Internal Tool Builder: Describe the tool your team needs and Construct writes, validates, and publishes a working internal app straight into your cloud desktop.
- Scheduled Jobs with History: Schedule an agent prompt, a connected-app action, or a whole workflow to run once or repeatedly, with a full record of results.
- Inspectable Memory: Preferences, decisions, and project context are stored with supporting evidence and history, and can be reviewed, corrected, or forgotten.
- Shared Team Workspace: People, agents, files, apps, and conversations live in one workspace with invitations, roles, and precise access controls.
- Multi-Channel Access: Message Construct from the web, Slack, Telegram, Discord slash commands, or its own native email inbox, with per-channel routing and access policies.
- Cited Research Reports: Gathers sources, compares details, and turns open-ended questions into cited research you can review or share.
- Resumable Long Runs: Jobs that fail partway through resume from where they stopped rather than restarting, targeting reliability on multi-step work.
- Data Ownership and BYOK: Workspaces are isolated and never used as training data, you own the output, and Pro allows bringing your own model keys.
Best for
- Process Automation: Turning a recurring manual business process into a versioned workflow anyone on the team can trigger.
- Internal Tooling: Shipping a small internal app for a team need without pulling in engineering time.
- Inbox and CRM Follow-Through: Letting an agent read, reply, and close the loop across connected tools instead of leaving half-finished automations.
- Market and Topic Research: Producing cited research reports on a subject for review or client delivery.
- Scheduled Reporting: Running a recurring report or data pull on a schedule and keeping the result history in one place.
- Solo Founder Leverage: Handing off operational work as a one-person company without hiring a first operations employee.
- Cross-Channel Team Requests: Letting teammates hand work to the agent from Slack, Discord, Telegram, or email without changing tools.
