IMPORTANT Depending on whether you select Extrusion/2D or 3D Freeform for Geometry type under the
Component Dimensions category, not all of the following options can be set by the user. Settings that are
deactivated for 3D Freeform spaces are Filter boundary set, Maximum gap size, and Ignore Holes.
18 For Boundary set, specify how the bounding objects for the space should be selected:
If you want to
automatically select bounding objects visible in the
drawing area
select bounding objects manually in the drawing
19 To determine which object types should be used as bounding objects, select an option for Filter boundary
set:
Walls only: If you select this option for filter boundary set, only walls, curtain walls, door and window
assemblies, and freestanding curtain wall units will be considered as bounding objects for associative
spaces. In many cases, this will be sufficient.
AEC Objects: If you select this option for filter boundary set, all objects listed in
and Object Outlines for Associative 2D or Extruded 3D
bounding objects for associative spaces.
AEC Objects, lines, arcs, circles, and polylines: If you select this option for filter boundary set, all objects
listed in
1593, as well as AutoCAD lines, polylines, circles, and arcs can will be used as bounding objects for
associative spaces.
All Linework: Spaces can be generated from the outlines of AEC objects. For a complete list, see
Bounding Objects and Object Outlines for Associative 2D or Extruded 3D
This setting is valid for extruded 3D spaces and 2D spaces only. A 3D freeform space always uses the AEC
Objects filter.
20 If you have selected to generate a space from bounding objects and linework, specify if the space detection
should allow for gaps between the bounding objects:
If you want to
create a space from lines and objects that
contain one or more coplanar gaps
create a space from closed sets of lines and
objects only
This setting is valid for extruded 3D spaces and 2D spaces only. A 3D freeform space does not allow for
gaps in the bounding geometry.
21 If you have selected to generate a space from bounding objects, or from a combination of bounding objects
and AutoCAD linework, specify whether you want to ignore objects or linework enclosed within in the
boundary set:
If you want to
generate a space from only the selected
objects and linework, and disregard any
linework or objects within the boundary set
generate spaces for objects or linework
within the boundary set
This setting is valid for extruded 3D spaces and 2D spaces only. A 3D freeform space will by default exclude
enclosed objects if they are valid bounding objects for 3D freeform spaces. If they are not, they will be
ignore. for a complete list, see
