Specifies a drawing-units value for automatic scaling of blocks, images, or xrefs when inserted or attached to a drawing.

Type:	Integer
Saved in:	Drawing
Initial value:	1 (imperial) or 4 (metric)

For information on how the scale of a block or drawing inserted into the current drawing is calculated, see About Block Units and Insertion Scale.

Note:

• US Survey Feet is a historical survey unit that's about 2 parts per million larger than the International Feet unit. This difference is significant only at scales used for mapping in the U.S. The US Survey Feet setting is supported only for inserting or attaching drawings starting with AutoCAD 2017-based products. Drawings opened in prior versions will treat the US Survey Feet setting as Unitless.
• US Survey Inch, US Survey Yard, and US Survey Mile are supported on AutoCAD for Mac only.
