Also, for house or other similar type building plans Don, I doubt that you want any Precision-- Drawing Space Units or Dimensions-- any higher than 2, (right?)
You draw in Millimeters (mm) don't you? A Precision of 2 would be 1/100th of a Millimeter-- smaller than anyone can measure, tick with a pencil, and/or cut.
A Precision of 2, using the Metric system/Millimeters, would result in a Precision equivalent to 1/.254th of an inch in the English system (that's "one/two-hundred-fifty-fourths of an inch"). In the USA, using the English system, for building construction plans, I don't think anyone with experience uses a Precision higher than 1/16"-- it would be silly and inefficient to do so.
(I think I did that conversion right; if not, someone will correct me. Either way... a Precision greater than 2 in the Metric system, using Millimeter as Space Units is pretty danged small.)
