Offset>Crt<18.699>/<10.000>
: Enter the desired side line offset (20).
Distance>Crd<57.919>/<10.000>
: Enter the desired frontage offset (65), as measured along the selected side line. If
the Align Settings under Tools is set to Offset-Offset, then the offset distance applies to the minimum separation
distance from the frontage line to the selected building corner. (In our example, the Offset-Offset setting, using the
same offsets of 20 and 65, would shift the building slightly closer to the front lot line, since at the 20 offset, the frontage
lot line is curving away from the building. Offset-Offset holds the offset distance to the actual building corner, and
Offset-Distance measures along the side lot line itself)..
The new building location then draws and the original building remains. If this is correct, use E for Erase to remove the
old building. Otherwise, remove the new building and repeat the process.
