I mile is 5680' I believe

Assuming that,

If 1" = 5680'

Then

12 X 5680' = 68,160

If you divide 68,160 by 4

Then

I believe you will have 4" = 1 Mile

Scale Factor 17,040

4" = 5280'

1" = 1320'

1" = 15840"

15840

~~~~~~~~~

3/8" = 1'-0"

3" = 8'

3" = 96"

1" = 32"

32

~~~~~~~~~

1/4" = 1'-0"

1" = 4'

1" = 48"

48

~~~~~~~~~

1" = 1'-0"

1" = 12"

12

~~~~~~~~~

3/4" = 1'-0"

3/4" = 12"

3" = 48"

1" = 16"

16

~~~~~~~~~

1" = 300'

1" = 3600"

3600

~~~~~~~~~

1" = 20'

1" = 240"

240

~~~~~~~~~~

1/8" = 1'-0"

1" = 8'

1" = 96"

96

~~~~~~~~~

Test it

IN MS draw a line 5280 feet long

Go to PS, zoom the viewport to 1/15480XP

Measure the line, it'll be 4"

zoom the VP to 1/17040xp

measure the line.

Well, I did something almost exactly like that
I had drawn grids within grids, all on different layers with different colors.
One grid was 100 yards per square and the other grid was a mile per square, it was cool.

So, when I plotted, I had to go to 4" = 1 mile in order to plot to a D size sheet and still be able to scale with a scale rule

Hey, draw a rectangle, whatever size, then put this little macro I created into a custom button and try it

Code: [Select]
^C^Chatch;Ansi37;\45;

It utlizes Hatch pattern Ansi37 to draw a grid.

After you initiate the macro, you will be prompted for a scale factor, enteer the scale factor at the command line then pick the rectangle. You can use these scale factors below -----> Hope you like

Grid Size              Scale Factor

1/8"                          1
1/4"                          2
1/2"                          4
1"                             8
3"                            24
6"                            48
1'                             96
1 Yard (3')               288
1 Mile  (5,280')     506880

Ps

You were right about the feet per mile 5,280'

Sorry about that. it is rhe correct scale factor above that I posted with the macro

Also, your above scale factor was written  15480xp
I believe you meant 15840 which is
12 X 5,280' (1mile)  / 4 = Scale factor 15840 (4" = 1 Mile)
It works great for scaled site plans

I made a few also as you can see  LOL
Did you try the little grid macro? It works great!

I think my brain is cooked at the moment

If we were doing 1" = 1mile, wouldn't the scale factor be 63360?

One more correction   LOL

OK, 1 mile X 12 = 63360 if we are doing 1" = 1mile however
If you are using my above macro, keep in mind that the grid by default is 1/8" therefore, you need to do 63360 X 8 to get your grids to equal 1 mile each square. Therefore the scale factor is 506880

All scale factors i posted with that macro are correct because of the grid defaulting to 1/8"

Or, you create your own partial menu.

Example -------->


Code: [Select]
