Question
A
When you use object snap (osnap), model space objects will be measured in paperspace using the model space units. Se the result will be reported in true model units, not in the current "paper" units defined by the viewport scale. The osnaps makes the difference.
This applies both to the DIST and MEASUREGEOM commands, and to dimensioning.
This behaviour differs between AutoCAD 2006 and version 2007 (plus higher) - the version 2006 has used paperspace units even for osnap-distances.
If you want to dimension modelspace objects with osnaps and display the values in paperspace units, set the DIMASSOC variable to 1. If you want to measure distance between modelspace objects with osnaps and represent the values in paperspace, use an alternative command for measuring - instead of DIST, use the Lisp function:
(strcat "Distance "(rtos(getdist"First point: ")))
