I have multiple buildings on my worksite, with multiple alarmed areas inside each building. I want to know if there is a way to import a picture of a floor plan of a building, AND line it up with the cell grid in order to highlight where specific rooms or multiple rooms are.
I DON'T want a world map, or a map of the USA. (Regardless of what Google seems to think)
And if it is possible to create such a thing in Excel, is there a way to create/highlight access routes on the map?
I've imported a floor plan image into Excel and adjusted transparency, but is there a way to get Excel to highlight certain sections of the map based off cell coordinates, in a way that would actually affect the image or do I need to make a complete overlay from inside Excel and then remove the image?

ActiveSheet.Shapes(Id).Visible = True ' or False, whereIdis the index or name of a section image.ActiveSheet.Shapes("Freedom: Shape 7").Visible = True ' or False:
