Some objects have their bounding behavior set to No An object that is normally valid for bounding associative spaces can be manually excluded from a bounding set by setting a property either on the Properties palette (Bound Spaces=No) or in the object style (This style may act as boundary for automatic spaces=No) that declares this object or its style as non-bounding. This can be useful if you want to exclude some objects, like the walls of individual stalls in a bathroom, in order to generate the total space of the room. If the non-bounding setting is on an object that is needed to close the space, it will cause the enclosed space to be considered non-closed. Verify that all objects in your bounding set have been defined as bounding, as described in "Setting an Object Style as Bounding" on page 1590 and "Setting an Object Instance as Bounding" on page 1590. Bounding walls have been placed in the same cleanup group as non-bounding walls If a wall that is non-bounding intersects with a wall that is bounding, and they are in the same cleanup group, the wall that is bounding will be considered non-closed because of its cleanup with the non-bounding wall. As a result, no space can be generated even if the geometry would otherwise be valid. In that case, you need to create a new cleanup group and place only the non-bounding walls in that group. Some bounding objects are placed on a frozen or hidden layer Bounding objects that have been placed on a frozen or hidden layer cannot be used in the generation of associative spaces. Verify that all necessary layers are visible and unfrozen. For more information, see "Use Layers to Manage Complexity" in the AutoCAD help. The visible drawing area was changed by zooming or panning in between activating the Add Space command and selecting the bounding objects When you generate associative spaces, only bounding objects visible in the drawing area at the time you start the space generation are included in the selection set. If you have zoomed or panned before generating spaces, the space detection is not automatically updated to the new drawing area. To update the selection set, use the v (reset Visible boundaries) option on the command line. This option will update the visible drawing area to its current extents. Then, generate the space again. When I try to generate a space from the outlines of walls, I get unexpected space boundaries. How can I fix this? The All Linework option on the Properties palette lets you generate spaces from the outlines of AEC objects. This can be useful for generating spaces to deduct from other spaces, like a mass element representing a cable shaft, or walls that represent a construction space. A space generated from wall outlines should look like this: In some cases, the space generation may result in different and segmented boundaries like this: If this is the case, your maximum gap size was too big, and the end wall conditions between walls were not calculated correctly. Recreate the space with a very small maximum gap size. When I update the bounding geometry for associative spaces (like for example, I move a wall to a different position) the space does not update. In some cases, it displays a defect marker, but in other cases just does not update. How can I get the space to update? The following 4 factors can be responsible for spaces not correctly updating: 1.The space is no longer associative Verify that the Associative setting on the Properties palette is still set to Yes. If it has been accidentally set to No, the space loses its associativity to the bounding objects. The space no longer updates, but displays no defect marker.
