A hot spot is a rectangular area on a markup layer that links to another object or an image elsewhere in the same file or within a completely different file.
Hot spots can be created linking an area in one file to an area in another file. When you double-click on a hot spot, the target file opens automatically for you to view in a separate window.
Additionally, you can also process multiple hot spots at once through SmartPlant Foundation or Directa using a Hot Spot Query.
