Multilines are composed of parallel lines, called elements.
When you draw a multiline, you can use the STANDARD style, which has two elements, or specify a style that you created previously. You can also change the justification and scale of the multiline before you draw it.
Multiline justification determines which side of the cursor that the multiline is drawn, or whether it is centered on the cursor.
Multiline scale controls the overall width of the multiline using the current units. Multiline scale does not affect linetype scale. If you change the multiline scale, you might need to make equivalent changes to the linetype scale to prevent dots or dashes from being disproportionately sized.
Create Multiline Styles
You can create named styles for multilines to control the number of elements and the properties of each element. The properties of multilines include
- The total number of elements and position of each element
- The offset distance for each element from the middle of the multiline
- The color and linetype of each element
- The visibility of the lines, called joints, that appear at each vertex
- The type of end caps that are used
- The background fill color of the multiline
Elements with a positive offset appear on one side of the middle of the multiline; elements with a negative offset appear on the other side of the middle of the multiline.
How to Create a Multiline Style？

- In the Multiline Style dialog box, click New.
- In the Create New Multiline Style dialog box, enter a name for the multiline style and select a multiline style from which to start. Click Continue.
- In the New Multiline Style dialog box, select the parameters for the multiline style and click OK.Descriptions are optional and can be up to 255 characters, including spaces.
- In the Multiline Style dialog box, click Save to save the multiline style to a file (the default is acad.mln). You can save multiline styles to the same file.If you create more than one multiline style, save the current style before creating a new one or you lose the changes to the first style.
How to Draw a Multiline？
- At the command prompt, enter MLINE.
- At the Command prompt, enter st to select a style.
- To list available styles, enter the style name or enter ?.
- To justify the multiline, enter j and select top, zero, or bottom justification.
- To change the scale of the multiline, enter s and enter a new scale.Now draw the multiline.
- Specify the starting point.
- Specify a second point.
- Specify additional points or press Enter.If you specify three or more points, you can enter c to close the multiline.
How to Modify Multilines？
Edit a Multiline Style
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.
- At the Command prompt, enter MLSTYLE.
- In the Multiline Styles dialog box, select the style name from the list. Click Modify.
- Click Element Properties.
- In the Modify Multiline Styles dialog box, change the settings as needed.
- Click OK.
- In the Multiline Styles dialog box, click Save to save the changes to the style in the MLN file.
Delete a Vertex From a Multiline
- At the Command prompt, enter MLEDIT.
- In the Multiline Edit Tools dialog box, select Delete Vertex.
- In the drawing, specify the vertex to delete. Press Enter.
Create a Closed Cross Intersection
Multilines can intersect in a cross or a T shape, and the crosses or T shapes can be closed, open, or merged.
- At the Command prompt, enter MLEDIT.
- In the Multiline Edit Tools dialog box, select Closed Cross.
- Select the multiline for the foreground.
- Select the multiline for the background.The intersection is modified. You can continue selecting intersecting multilines to modify, or press Enter to end the command.
Use Common Editing Commands on Multilines
You can use most of the common editing commands on multilines except
To perform these operations, first use EXPLODE to replace the multiline object with separate line objects.
If 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.
