Adding the ThingWorx profile package to a model (Integration for PTC ThingWorx)
When the Java Profile or C++ Profile is added to a model, the ThingWorx Profile is added as well.
To add the ThingWorx profile package to a model:
1. Ensure that you have Database Write access permissions to the Model's Database.
2. Open the Model to which you want to add the ThingWorx Profile package.
3. On the Tools menu, click Add Profile.
4. Select the ThingWorx entry, and then click OK.
* 
Do not make changes to the ThingWorx profile. Any changes you make will be lost when the profile is updated.
Note that you can create Tag Definitions outside of the ThingWorx profile, and link those Tag Definitions to Stereotypes in the ThingWorx profile. When the ThingWorx profile is updated, the links will not be broken.
Do not create copies of the ThingWorx profile within a model, or create copies of the ThingWorx profile through XMI Import/Export. The copies of the ThingWorx profile will not work correctly and you will not be able to update the copies through the Update All Profiles command.
