Enabling Support for Custom Parts
In the Creo Parametric HTML client, you can enable support for custom parts that extend wt.part.WTPart. However, a custom part must be modeled before any changes are made to the Creo Parametric HTML client. For more information on extending the Windchill object model, see the Windchill Specialized Administration Guide.
