Tip: AutoCAD's Big Problem  7 Sep, 2006 By: Bill
Burchard,Michael Partenheimer  For years, AutoCAD hasn't worked
well with large coordinates in civil engineering and survey
drawings. Here, we offer some workarounds.  There's a bug in
AutoCAD that's been around for years: AutoCAD doesn't work well
when using large coordinate values. Hatches won't fill, the Trim
command doesn't always work and other annoying "gotchas" can
occur.  So what is a "large" coordinate value? We're referring
to x,y values in the millions. Of course, this is not a problem
for the many users who work with much smaller coordinate values.
But if you do work with large coordinate values, we have some
workarounds to help you overcome AutoCAD's shortcomings.  Why
Use Large Coordinate Values? Civil engineering and surveying CAD
users generally draw objects with endpoints that correspond to
precise locations in the real world. The x,y coordinates
correspond to some set standard of Easting and Northing
coordinates, usually State Plane. This answ
