# PTC Windchill PLM Engineering AI Skill Guide (GPT & Codex)

## Overview & Engine Architecture
PTC Windchill exposes powerful Java RMI / Server-Side APIs, **Info\*Engine task scripting (`.jsp` / `.xml`)**, and **OData REST interfaces** for high-volume enterprise data loading and custom listener automation. GPT/Codex acts as a Principal Windchill PLM Automation Developer and Enterprise Integration Specialist, delivering **Java MethodServer event listeners**, **Info\*Engine web service tasks**, **`LoadFromFile` XML bulk import templates**, and **automated CAD publishing scripts**.

## Operational Capabilities & Agent Directives

1. **Windchill Java Server API Development**: Author robust Java extensions extending `StandardManager` and `ServiceEventListenerAdapter` to intercept Part/Document lifecycle events (e.g. `POST_CHECKIN`, `PRE_PROMOTE`).
2. **`LoadFromFile` XML Bulk Ingestion**: Construct syntactically validated XML files and CSV mapping headers for `windchill wt.load.LoadFromFile` to import mass part catalogs.
3. **Info\*Engine Task Development**: Author custom Info\*Engine tasks (`.jsp`) querying `wt.query.QuerySpec` to return structured I*E VDB XML datasets.
4. **Automated CAD Worker Orchestration**: Script the automated dispatch and health monitoring of Creo/SolidWorks CAD worker conversion queues.

## Production XML Automation: Windchill `LoadFromFile` Part Definition Template

Save this file as `bulk_parts_import.xml` and execute via `windchill wt.load.LoadFromFile -d bulk_parts_import.xml -u admin_user -p password`:

```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE NmLoader SYSTEM "standardX24.dtd">

## Technical Troubleshooting Matrix

| Issue & Failure Signature | Root Cause Analysis | Diagnostic & Resolution Pathway |
| :--- | :--- | :--- |
| **`LoadFromFile Fails: Container not found`** | The `csvcontainerPath` does not match the exact internal organization or product context name. | 1. Query container path: `windchill wt.load.LoadFromFile -test ...`.<br>2. Verify container format: `/wt.inf.container.OrgContainer=OrgName/wt.pdmlink.PDMLinkProduct=ProdName`. |
| **`RemoteMethodServer: InvocationTargetException` in Custom Java Code** | Unhandled `WTException` inside server-side transaction block causing database rollback. | 1. Wrap all persistence logic in `Transaction tr = new Transaction(); try { ... tr.commit(); } finally { tr.rollback(); }`.<br>2. Check detailed stack trace in `MethodServer.log`. |
| **Info\*Engine Task Returns `404 Not Found`** | Task `.jsp` file placed in wrong codebase directory or not mapped in `tasks/` directory tree. | Place custom tasks in `C:\ptc\Windchill\tasks\custom\` and invoke via `/Windchill/tasks/custom/mytask.jsp`. |
| **WVS Worker Fails with `CadWorkerException: Worker Timed Out`** | Native CAD executable (Creo Parametric / SolidWorks) hung on a popup dialog on the worker host. | 1. Log into CAD worker machine.<br>2. Close modal license or update dialogs in CAD.<br>3. Verify CAD launches cleanly in headless mode. |

## Command Line Syntax & Batch Processing

```bash
# Execute Windchill Bulk Part Loader via CLI
windchill wt.load.LoadFromFile -d "C:\Data\bulk_parts_import.xml" -u admin_user -p SecurePass

# Query MethodServer Thread Dump via ServerManager CLI
windchill wt.manager.ServerManager -dump
```

### Essential File Locations
- **Codebase Root**: `C:\ptc\Windchill\codebase\`
- **Info\*Engine Tasks**: `C:\ptc\Windchill\tasks\`
- **DTD Definitions**: `C:\ptc\Windchill\codebase\standardX24.dtd`

## Agent Operational Directive
> **MANDATORY**: In custom Windchill Java extensions, execute database operations within explicit `wt.pom.Transaction` blocks to guarantee ACID rollback on errors. Validate XML tags against `standardX24.dtd` before running `LoadFromFile`.
