Get MORE done

Automation shouldn't live on one desk.

Accelerate the BUSINESS, NOT just the Department.

Your Process → Your Code

And it stays this simple — same call shape every time

Python · batch export to STEP

# every part in the working directory
parts = creoson("creo", "list_files", {"filename": "*.prt"})

for part in parts["filelist"]:
    creoson("file", "open", {"file": part})
    creoson("interface", "export_file",
            {"file": part, "type": "STEP"})

Python · release stamp + drawing PDF

# stamp every part, then refresh its drawing
parts = creoson("creo", "list_files", {"filename": "*.prt"})

for part in parts["filelist"]:
    drw = part.replace(".prt", ".drw")

    creoson("file", "open", {"file": part})
    creoson("parameter", "set",
            {"file": part, "name": "RELEASE", "value": "B"})
    creoson("file", "save", {"file": part})

    creoson("file", "open", {"file": drw})
    creoson("drawing", "regenerate", {"drawing": drw})
    creoson("interface", "export_pdf",
            {"file": drw, "use_drawing_settings": True})
    creoson("file", "save", {"file": drw})

Your Process → Your AI Agents

Open the main assembly in creo, lookup the purchased components and raw materials in ERP, and estimate the cost of the design.

Export DXF files for all Sheet Metal parts that have a flat pattern.

Which models and drawings do not conform to the company design standards?

Add this note "CRTICIAL: Debur & Degrease BEFORE Plating" to all Sheet Metal Parts, and update the drawings to show the node above the Title Block.

Bump All Family Table Instances to be one letter higher than the current release model release version.

Import all STEP files and apply the company start part required parameters and defaut values.

Generate PDF exports for all drawings, but make sure the file name includes the version and release in the PDF filename.

What items are the most expensive in-house items for the design?

Enabling "just ask" — use your OWN Local AI or Cloud AI to drive Creo Parametric via MCP.
MCP endpoints can be secured with per-system/user access keys over TLS/HTTPS.
You can use CREOSON to support your own MCP implementations today!
