Use this procedure to set the Bound Spaces property of objects designed to bound associative spaces in the object style. You can use this method for all boundary objects that use styles. When an object style is set to bound spaces, all objects of that style will bound associative spaces. You can however override the Bound Spaces property for an individual object of that style in the Properties palette.
For example, if walls of a specific style - such as toilet stall walls or half-height kitchen counter walls - should normally not be used as boundary objects, you can set the Bound Spaces property of the wall style to No, so that any walls of that style are ignored when you generate a space.
