cad-skill

Control local CAD applications on Windows including launching apps, opening files, checking status, closing apps, detecting active or running apps, detecting common executable paths, and saving user-provided executable paths.

This skill allows an AI assistant to control locally installed CAD applications on Windows.

Supported software currently includes:

• solidworks
• catia
• creo
• ug (Siemens NX)

The skill enables launching CAD software, opening files with specific applications, checking running status, closing applications, and detecting active CAD windows.

This skill is intended for local workstation automation.

Important Constraints

The assistant must follow these constraints when using this skill:

1. Do not scan the entire computer filesystem.
2. Do not traverse all directories on disk.
3. Do not read the Windows registry.
4. Only use paths stored in config.json.
5. Only check predefined candidate install paths.

If the executable cannot be located:

• ask the user to provide the full executable path
• then call set_app_path to store the path.

Supported Applications

Currently supported CAD software:

• solidworks
• catia

  "args": {
    "app": "solidworks"
  }
}

Example Usage

Launch SolidWorks:

json

{
  "skill": "launch_app",
  "args": {
    "app": "solidworks"
  }
}

open a STEP file in SolidWorks:

json

{
  "skill": "open_file_in_app",
  "args": {
    "app": "solidworks",
    "file_path": "D:\\DESKTOP\\solvi_project\\moca\\moca.STEP",
    "auto_launch": true,
    "wait_seconds": 5
  }
}

Save a user provided executable path:

json

{
  "skill": "set_app_path",
  "args": {
    "app": "solidworks",
    "path": "E:\\Program Files\\SOLIDWORKS Corp\\SOLIDWORKS\\SLDWORKS.exe"
  }
}

Note

This skill is designed for local CAD workstation automation.

It intentionally avoids heavy filesystem scanning to maintain fast response and predictable behavior.
