Quick Reference

Multiline objects are composed of 1 to 16 parallel lines, called elements. To modify multilines or their elements, you can use common editing commands, a multiline editing command, and multiline styles.

Special multiline editing features are available with the MLEDITcommand including the following:

Add and Delete Multiline Vertices

You can add or delete any vertex in a multiline.

Edit Multiline Intersections

If you have two multilines in a drawing, you can control the way they intersect. Multilines can intersect in a cross or a T shape, and the crosses or T shapes can be closed, open, or merged.

Edit Multiline Styles

You can use MLSTYLE to edit multiline styles to change the properties of multiline elements or the end caps and background fill of subsequently created multilines.

Multiline styles control the number of line elements in a multiline and the color, linetype, lineweight, and offset of each element. You can also modify the display of joints, end caps, and background fill.

Multiline styles have the following limitations:

You cannot edit the element and multiline properties of the STANDARD multiline style or any multiline style already used in the drawing.
To edit an existing multiline style, you must do so before you draw any multilines in that style.

NoteIf you use MLSTYLE to create a multiline style without saving it, and then select another style or create a new style, the first MLSTYLE properties are lost. To maintain the properties, save each multiline style to an MLN file before creating a new one.

Use Common Editing Commands on Multilines

You can use most of the common editing commands on multilines except

BREAK
CHAMFER
FILLET
LENGTHEN
OFFSET

To perform these operations, first use EXPLODE to replace the multiline object with separate line objects.

NoteIf you trim or extend a multiline object, only the first boundary object encountered determines the shape of the end of the multiline. A multiline cannot have a complex boundary at its endpoint.
