Reference:AecBoundingObjectRule Class

The following list shows all members of the AecBoundingObjectRule base class:

namespace Autodesk.Aec.SpaceOffsetRulesManager
{

public abstract class AecBoundingObjectRule : AecSpaceOffsetBaseRule
{

public AecBoundingObjectRule();
public abstract bool Apply(

Autodesk.AutoCAD.DatabaseServices.ObjectId idSpace,
Autodesk.AutoCAD.DatabaseServices.ObjectId idObject);

}

Bounding Adjacency Rule (SpaceOffsetRulesManager.AecBoundingAdjacencyRule Base Class)

Bounding adjacency rules define an offset for segments of the space base profile depending on the space that is adjacent
to this segment. A common use case for gross offset profiles is that bounding adjacency rules define that the boundary
should be offset to the center of the bounding object at interior walls and to the outside of the bounding object at
exterior walls.

Implementation of a Bounding Adjacency Rule

To implement a bounding adjacency rule, you need to add a new class that is derived from
SpaceOffsetRulesManager.AecBoundingAdjacencyRule. As with all previously described offset types, the new class needs to
implement the Apply interface of this base class and register itself for the object types it should be called for in the
constructor by calling the base method AecSpaceOffsetRuleBase.RegisterType(). The Apply method each rule needs to
implement has the following form in AecBoundingAdjacencyRule:

public abstract bool Apply(Autodesk.AutoCAD.DatabaseServices.ObjectId idSpace,
Autodesk.AutoCAD.DatabaseServices.ObjectId idObject,
Autodesk.AutoCAD.DatabaseServices.ObjectId idAdjSpace);

The first ObjectId argument is the current space for which the offset boundary is to be calculated. The second ObjectId
is the bounding object between the space from the first argument and the adjacent space. The third argument is the
ObjectId of the adjacent space. When there is no adjacent space, which is the case at exterior walls, the value of this
argument will be ObjectId.Null. The following example shows the frame for a new space rule called
BoundingAdjacencyRuleGross:

namespace AecSpaceOffsetStandardBasic
{

public class BoundingAdjacencyRuleGross : AecBoundingAdjacencyRule
{

public BoundingAdjacencyRuleGross()
{
}
public override AecSpaceOffsetInfo Apply(ObjectId idSpace, ObjectId idObject, ObjectId idAdjSpace)
{

}

Sample Bounding Adjacency Rule BoundingAdjacencyRuleGross

The following example shows the implementation of a bounding adjacency rule that is used in the sample project. It
defines an offset to the center of the bounding object for 2 spaces at interior walls and an offset to the outside of the
wall if there is no adjacent space.
