    Posted: 20.Sep.2013 at 22:56
I am working on a dwg a client has sent over.  When I meassure a door it comes in at 7/8" when it should be 3'.  Does any one know by what factor I should rescale it too.  I'm using ACAD 2010
Thanks

Hello Nsato, your re scaling is strange to me, how can anyboy draw 7/8" what is suposed to be 3' ?
Files are suposed to be done at scale 1/1 not depending on the units but if you set the DDUNITS correctly there should not be any problem between files of different units.
Have you verified all the datas before? :
Command UNITS , length , angle , insertion scale .
If you re scale the entire file, do it from 0,0,0 in case you are using X,Y,(Z) locations.
You said that you have verified a length of 7/8", did you do it with the DISTANCE command or by placing a dimension? --> then verify the setings of the dimension with the command DDIM, principal units etc...
If the file containts blocks verify the unit of the blocks by opening the property pannel ( CTRL + 1 ).

How it happened or why it was done that way isn't the point.  Follow the advice heinsite provided and you'll be fine.  You might also want to tell your client that in the future he/she should draw everything full size and not try to scale it.

One possibility for the scaling issue is that the drawing was done using a graphics program like Illustrator then saved or exported as a DWG file.  During the conversion process the scale got messed up.

Don't use a calculated scale factor -- you can do it with precision rather than with something rounded, no matter to how many decimal places.  Your 7/8 may also be rounded for display (or Dimensioning settings if that's how you measured it), and may really be something wackier.
 
Call up the Scale command, select everything, give it some base point around which to Scale things, choose the Reference option, pick the actual width of the door as the reference size, using object snap so it will find what it actually is, and give it 36 for the new size.
