The formulas shown below are the key to understanding AutoCAD and 
PlotWorks. .

AutoCAD Image x AutoCAD Scale = Size

Size x Printing Scale = Output size

Example: (36 x 24) x (1=2) = 18 x 12

The image creator designs an image in AutoCAD in a nonspecific set of units 
called drawing units. The creator then designates an AutoCAD scale which 
translates the image into a specific paper size. If the scale and size specified by the 
creator are incorrect , the resulting size in AutoCAD is wrong. 

PlotWorks addresses this issue by allowing the user to independently scale to a 
printed image size. The user only has to designate the scale or a final size in 
PlotWorks.

For example: If in AutoCAD a Scale is specified and the size is wrong, PlotWorks 
will detect the error during pre-checking. PlotWorks will then display the 
resulting nonstandard natural image dimensions (for example: 33" x 22" or 42" x 
28") and the respective nonstandard scales so that the error can be corrected. 

In the example on the next page, it is likely that the user intended to produce a D1-
size plot (36x24), but the Scale was specified incorrectly at 1=48 instead of 1=12.
