Use this procedure to apply a wall endcap style to a wall style. When a wall endcap style is applied to a wall style, all walls of that style will have the specified at both ends. You can override the style-defined endcap style by assigning a different endcap to one wall end.
Expand Wall Styles, and select the wall style to which you want to apply the wall endcap style.
Click the Endcaps/Opening Endcaps tab.
For Wall Endcap Style, select the style you want to apply.
The endcap style is applied to all existing walls of that style, as well as all new walls of that style.
Tip: The endcap style defined in the wall style is always applied to both ends of the wall. If you want a different endcap for each end of the wall, you can override the style-defined endcap.
