I am trying to create a grid that can be used as part of the data driven pages. I am using the "Grid Index Features (Cartogaphy)" tool. What I would like is a Grid that corresponds to 1:10,000 scale when used in the data driven pages tool. At the moment I am getting a grid which is tiny and does correspond with my selected scale.
I have detailed the process below:
Output Features Class : This is just called "GRID"
Input Features: This is a polyline one feature line.
Generate Polygon ticked
Use Page Unit and ticked and this then self generates that following attributes
Map Scale  = 10000
Polygon Width = 1cm
Polygon Height = 1cm
x coordinate = 452656.225852325
y coordinate = 518194.9136161832
Number of Rows = 40
Number of Columns = 45
Starting Page Number = 1

I have attached a screenshot of the result that I get. If anyone can help that would be great.
