Engineering Drawings to Verified STEP Models

Saves ~4 hr

Details

Converts a package of 2D engineering drawings into dimensionally verified STEP models with a full audit trail. For each sheet the agent inventories the title block, builds a provenance-tracked dimension table (every value labeled, measured, computed or flagged as an assumption), hand-computes acceptance values (bounding box, volume, cross-section areas) from the drawing arithmetic BEFORE modeling, then builds a parametric CadQuery model in the Parametric Part Designer with live dimension checks, reconciles every check, verifies the solid independently with face distances, mass properties and sections, renders line drawings with hidden edges to lay over the source sheet, and writes a per-part tolerance record with acceptance bands under the sheet's general tolerance standard (e.g. ISO 2768-m). Finishes with a package report and a human review gate for the open engineering questions. Deliverables per part: exact B-rep STEP, watertight STL, screenshots, the parametric script and the verification evidence.

Inventory the Drawing Package

Goal: Catalog every 2D engineering drawing sheet provided and its title-block contract before any modeling starts. | Inputs: The attached engineering drawings (PDF or image), one part per sheet. | Outputs: A package inventory: for each sheet the drawing number, title, revision, scale, units, projection (first or third angle), material, the general tolerance note (e.g. ISO 2768-m), and the views present (front, side, plan, sections, auxiliary views). | Constraints: Many drawing PDFs contain no extractable text (labels are vector outlines), so read the rendered sheet visually. Record only what is drawn; do not invent values. | Success criteria: Every sheet appears in the inventory with all title-block fields filled and its view layout understood.

Frequently Asked Questions

How do I connect this workflow to my local agent like OpenClaw or Claude Code?

You can install the local MCP server by opening a terminal and running:

Install commands

npm install -g @agentpmt/mcp-router
agentpmt-setup

This will connect you to local agents like Claude Code, Windsurf, Grok Build, Cursor, etc.

Alternatively you can connect to the hosted version with this config block, no installation required:

Hosted MCP config

{
  "mcpServers": {
    "agentpmt": {
      "type": "streamable-http",
      "url": "https://api.agentpmt.com/mcp",
      "headers": {
        "Authorization": "Bearer <AGENTPMT_BEARER_TOKEN>",
        "x-instance-metadata": "{\"client\":\"generic-mcp\",\"platform\":\"remote\"}"
      }
    }
  }
}

How do I trigger this workflow?

You can use it here in the browser by clicking the 'Try It' button.

If you 'star' the workflow it will save to your dashboard for quick access.

To use the workflow in an external agent, make sure you have followed the steps to connect it to the MCP server and then copy / paste this prompt, or just tell it to use the AgentPMT MCP server and use this workflow.
