Using the MLSTYLE command, you can create the style
of multilines. When you invoke this command, AutoCAD
displays the Multiline Styles dialog box (figure). With
this dialog box, you can set the spacing between the
parallel lines, linetype pattern, colors, solid fill, and
capping arrangements. By default, the multiline style
(STANDARD) has two lines that are offset at 0.5 and 0.5. The options provided under Multiline Styles dialog
box are:

justifications are available for the MLINE command. They are Top, Zero, and Bottom.

line coincides with the points you selected on the
screen. This is the default option, see figure.

distance between the lines (offset distance) will be
reduced to half, as shown in figure. A negative scale
factor will reverse the order of the offset lines. For
example, if you enter a scale factor of -0.5, the order in
which the lines are drawn will be reversed, and the offset
distances will be reduced by half. If the lines are drawn
from right to left, the offsets are reversed.

drawing multilines. For example, if the multilines
are top-justified, the grips will be displayed at the

AutoCAD inserts a vertex point at the point
where you clicked on the object while selecting
it. Later, you can move the vertex by using
grips. Similarly, you can also use the MLEDIT

does not create two separate multilines. You can cut
away an area from any of the elements of a

selected for cutting the multiline do not have to be
on the same element of the multiline (figure). You
can select the two points that define the cut on
different elements of the multiline. When cutting a
