Updating the ThingWorx profile in a model (Integration for PTC ThingWorx)
* 
To update the ThingWorx profile in a model, you require Repository Write access permissions to the Model's Database.
Do not make changes to 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.
To update the ThingWorx profile in a model:
1. From Modeler, right-click ThingWorx Profile package, and then click Update All Profiles
2. From the dialog, select the check boxes to ensure that you have a version of the model prior to profile updates and any migration of data, and a version of the model after the profile updates and any migration of data are complete.
3. Click OK.
