Double-Line Polygon tool

Use the Double-Line Polygon tool to create a wide variety of open or closed polygons that have two parallel lines, a double-lined polygon with a width, or two parallel lines with a polygon fill. Double-line polygons can have as many as 32,767 vertices.

2.Enter the distance between the double lines in the Separation field on the Tool bar.

3.Click Preferences to open the Double Line Preferences dialog box and specify the tool’s default parameters.

Parameter	Description
Separation	Enter the distance between the double lines; same as the Separation field on the Tool bar
Control Offset	For the Custom Control Line mode, enter the distance from the top/right line of the cursor
Options
Create Lines	Creates a series of lines
Create Polygons	Creates a double-line polygon
Create Lines and Polygons	Creates parallel lines with a polygon between them; the polygon has a line weight of 0
Components	Click to define components between the double lines; see Applying components between double lines. Component fills are visible only for double lines created with Create Polygons or Create Lines and Polygons selected.

Alternatively, if Create Polygons or Creates Lines and Polygons is selected in the Double Line Preferences dialog box, after completing all but the final click, press the keyboard shortcut to automatically close the polyline. The shortcut also closes path-based objects, such as hardscapes and spaces, that function similarly to the Polyline tool. See Modifying special shortcuts to change the shortcut.

Mode	Description
Top Control Line	The cursor draws the top/left line
Center Control Line	Creates lines equidistant from the cursor
Bottom Control Line	The cursor draws the bottom/right line
Custom Control Line	Specify an offset value
Preferences	Opens the Double Line Preferences dialog box for specification of additional object parameters
Separation	The distance between the double lines; the value must be greater than zero
