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.

Edit
