Blocks, Images or Xrefs not inserting correctly?

Have you inserted Blocks, Images or Xrefs only to find they scale automatically to a different scale from what you specified?

AutoCAD makes use of the following system variables when inserting any of the three above mentioned Objects...

INSUNITS - Specifies a drawing-units value for automatic scaling of blocks, images, or xrefs inserted or attached to a drawing.
INSUNITSDEFSOURCE - Sets source content units value when INSUNITS is set to 0. Valid range is 0 to 20.
INSUNITSDEFTARGET - Sets target drawing units value when INSUNITS is set to 0. Valid range is 0 to 20.

These system variables allow AutoCAD to automatically scale Blocks, Images or Xrefs, thus reducing your need to scale them to your current working scale.

The following are some links that shed some more light on the subject.
