■ AEC Objects, lines, arcs, circles, and polylines: If you select this option, all objects listed in "Bounding Objects and Object Outlines for Associative 2D or Extruded 3D Spaces" on page 1593, as well as lines, polylines, circles, and arcs can be used as bounding objects for associative spaces. You can use this option to generate spaces from plans created in AutoCAD, where walls and spaces are represented by lines and polylines. ■ All Linework: If you select this option, spaces can be generated from the outlines of AEC objects. This is a useful option for defining spaces that are deducted from other spaces, like construction spaces. If an AEC object has been defined as non-bounding in its style or its object properties, it will be filtered out, regardless of whether it is included in the boundary set. For more information, see "Setting an Object Style as Bounding" on page 1590 and "Setting an Object Instance as Bounding" on page 1590. IMPORTANT If your selection set includes walls with different bounding conditions, make sure to put the walls in different cleanup groups. If a non-bounding wall intersects with a bounding wall, and they are in the same cleanup group, the cleanup with the non-bounding wall will create a hole in the bounding wall through which the space leaks. As a result, no spaces can be generated even if the geometry would otherwise be closed. 11 If you are generating a space from bounding objects, specify whether the space detection should compensate for gaps between the bounding objects: If you want to... Then... create a space from objects that contain one specify a value for Maximum gap size. The software will ignore any gap smaller or more colinear gaps than this value. create a space from closed boundaries only specify 0 (zero) for Maximum gap size. 12 If you are generating a space from bounding objects and linework, specify whether objects fully enclosed within in the boundary set should be deducted: If you want to... Then... generate a space from only the selected bounding objects, and not deduct any objects fully enclosed within the boundary set select Yes for Ignore holes. want objects fully enclosed in the boundary select No for Ignore holes. set to be deducted from the generated space NOTE The Ignore holes setting is applied only to objects that are part of the object selection set under Filter boundary set. For example, if your filter boundary set is Walls Only, then any columns inside the walls are not deducted from the generated space, even if the Ignore holes setting is No. In that case, regenerate the space using the AEC Objects filter. 13 If you need to generate spaces within boundaries that already contain a space, select Yes for Allow overlapping spaces. 14 For Geometry type, select Extrusion or 2D. 15 Enter the height dimension values for the generated space: If you want to... Then... specify the overall height of the space, including floor to enter a value for Overall space height. ceiling height, ceiling and floor thickness, and space above ceiling and below floor specify the ceiling height of the space enter a value for Ceiling height. specify a floor thickness enter a value for Floor thickness.
