Creating double lines

The Double Line tool creates a wide variety of constrained and unconstrained double lines. Set the width between the double lines, the offset from the cursor, and whether to create components between the double lines.

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

Parameter	Description
Separation	Enter the distance between the double lines; same as the Separation field on the Tool bar
Control Offset	For Custom Control Line mode, enter the distance from the top line of the cursor. The distance must be less than the Separation distance between the double lines.
Options
Create Lines	Creates parallel lines
Create Polygons	Creates a double-line polygon with closed ends
Create Lines and Polygons	Creates parallel lines with a polygon between them; the polygon has a line weight of zero
Components	Click to define components between the double lines

Applying components between double lines

In the Double Line Preferences dialog box, click Components. The Wall Components dialog box opens. Specify the component details.

Parameter	Description
Preview	Displays a preview of the components between the double lines, including the defined components; the preview is drawn from left to right, so the “top” of the preview, by default, indicates the left part of the double lines as they will be drawn. The arrow shows the drawing direction.
Overall Thickness	The thickness of the double line with components is defined by the sum of the component thicknesses
Components	Lists the components that form the structure of the double line, in order from left to right as displayed in the preview. To change the order of a component, click and drag within the # column. The Core designation applies to walls, but not to double lines.
New	Click to define the components between the double lines; see Creating wall components
Edit	Opens the Wall Component Settings dialog box to edit the selected component’s thickness and attributes (you can also double-click a component to open the Wall Component Settings dialog box)
Delete	Deletes the selected component; the double line thickness is adjusted accordingly

Offset 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
