I imagine the code would do something like:

Select range

If cell is white... do nothing and pass on to the next cell

If a cell is red...
check the colour of cell above...
If that is white, place border; if red do nothing...
check the colour fo the cell to the right....
If that is white, place border; if red do nothing...

Then repeat for cells to the bottom and the left.

End

Good afternoon all,

A building's ground floor plan is created visually by a user in Excel by
highlighting cells and filling them with the colour red. Each cell on the
workbook is equivalent to 1m2. The building must fit into a 50x50 plot area
B2:AY51.

I now need to enable the user to input different floor finishes within this
footprint. Therefore I wish to place an outline border of the drawn shape
into a new workbook so that the user can fill the shape with different colour
fills (each representing a different floor finsih, e.g. carpet, vinyl etc.)

Is there a way of creating a code to do this that can then be attached to a
button?


Many thanks,

Neil
