For example, the net offset profile cannot be defined by offsetting the profile only from the bounding walls. Usually, the wall is cut at doors and windows too. This rule type can be used to describe this in the offset profile calculated by the area calculation standard. Implementation of a Bounding Opening Rule To implement a bounding opening rule, you need to add a new class that is derived from SpaceOffsetRulesManager.AecBoundingOpeningRule. The new class needs to implement one or more of the Apply interfaces of the base class and register itself for the object types it should be called for in the constructor by calling the AecSpaceOffsetRuleBase.RegisterType() base method. Note that this rule can only be applied to the following classes: ■ Openings ■ Doors ■ Windows ■ Door and Window Assemblies Registering this rule for other object types will not have any result. The Apply method of that class that each rule needs to implement has the following syntax in AecBoundingOpeningRule: 1758 | Chapter 36 Spaces
