Link Wall Segments

The Link Wall Segments (local menu) option controls whether walls become linked as they are drawn. It is on by default, but If it is turned off walls will not become linked. You can tell if a wall is linked by selecting it. Any other segments linked to that wall will be highlighted. Since walls automatically linked when you draw then in proximity this option can be useful for drawing a wall close to another wall without having them link. For example, this can be useful for drawing cubicle walls in an office setting.
