Honestly, this should not be too hard to implement. You can already re-scale a floorplan, and set origin point. When bringing in a new background you should scale, and set a matching origin point, and it should be roughly accurate.
You may see it as just a small amount of work, however I deal with floorplans that update regularly:
- In new facilities we need to make initial plans prior to internals being completely finalized. Because Airwave does not allow replacement of the background, this forces us to either work off of old prints or re-create manually on new prints. Perhaps just a few walls changed, and now we have to completely re-create the design. This is a huge waste of time and source of major frustration.
- In existing facilities we have the same issue. We may re-work an area and move things around, and now must re-create a live floorplan with deployed APs if we are to be able to reference anything current.
Replacing the background image is an essential, fundamental requirement and it's pretty dissapointing Aruba has not understood that.
