This command sets lines and polylines on specified layers to
zero elevation which helps solve the common drafting problem of
linework getting moved to elevation such as with a grip edit
snapping to a 3D point. In the dialog, you select which layers to
check. When you pick OK, the program checks all linework on those
layers and sets their elevations to zero. The Track Linework Edits
option checks when the linework is modified to make sure the
elevations are zero. When this routine prints a message to the
command line whenever it moves the linework elevation to zero.
