If you select lines and other changeable objects in the same selection set, you
get varying results depending on the object selection sequence. The easiest
way to use CHANGE is to select only lines in a selection set or select only
objects other than lines in a selection set.
Specify Change Point or Values or [Properties]: Specify a new point, or press ENTER
to enter new values
Change Point or Values
Changes the selected objects. The result depends on the type of objects you
select.
Lines
Moves the endpoints of the selected lines that are closest to the change
point to the new point, unless Ortho mode is on. If Ortho mode is on, the
selected lines are modified so that they become parallel to either the X or
the Y axis; their endpoints are not moved to the specified coordinate.
