# Setting document scale on import of a 3/32" scan

## Recommended Posts

I have a site plan drawn at 3/32" scale. Am wanting to import and use it as a base, but am a loss when in document preferences, figuring out how to set scale first. I don't see 3/32" listed and not sure what to put in as a custom paper scale. Probably will end up enlarging and printing it final at 200%. What scale do I set it at now before importing?

okay, just saw a conversion scale factor of 1:128, will use that

For future reference (and for myself when I end up searching the forum for this the next time) here is the formula to figure out the scale factor for odd scales.

3/32" is actually shorthand for 1 foot = 3/32 of an inch. If you convert both sides to inches you get:

12 inches = 3/32".

You need to convert that so that one side is equal to 1 (one).

12 : 3/32 so multiple both sides by 32

12*32 : 3/32*32.        384 3 then divide both sides by 3

384/3 : 3/3.    384/3 : 1.    128:1

Thanks Pat!
