Add Thing Shape to Template

 

We can see that there is some overlap in the components of our HazardousAsset and LineAsset ThingTemplates. In particular, both want information about the product count. Because HazardousAsset inherits from LineAsset, would only need to change LineAsset. Follow the steps below to perform this change:

  1. Open the LineAsset Thing Template.
  2. In the Implemented Shapes field, enter and select InventoryManager.
  3. Save changes.
