Reference:AecSpaceOffsetRuleCollection Class The following list shows all members of the AecSpaceOffsetRuleCollection base class: namespace Autodesk.Aec.SpaceOffsetRulesManager { public class AecSpaceOffsetRuleCollection { public void AppendBoundingAdjacencyRule(AecBoundingAdjacencyRule rule); public void AppendBoundingObjectRule(AecBoundingObjectRule rule); public void AppendBoundingOpeningRule(AecBoundingOpeningRule rule); public void SetSpaceRule(AecSpaceRule rule); } } Implementing Offset Rules After creating a new standard class, rules must be implemented. The code so far can be compiled and the built assembly can successfully be loaded as an area calculation standard into AutoCAD Architecture and be applied to space objects in a drawing. However, no offsets will be created, because no rules have been set up yet. There are 4 different types of offset rules that can be combined to define an area calculation standard. A rule can be applied to one or more offset types (net, usable, and gross) in the implementation of AecSpaceOffsetStandard.InitRules(). For each rule type there is a base class that the implementation of a custom rule needs to derive from. All of these base classes are derived from one common abstract base class, so it is recommended to view that class first. AecSpaceOffsetBaseRule Abstract Base Class The AecSpaceOffsetBaseRule public abstract base class is a member of the namespace Autodesk.Aec.SpaceOffsetRulesManager and the base class for all rule classes. Void AecSpaceOffsetBaseRule.RegisterType(System.Type type) Method The only method the AecSpaceOffsetBaseRule base class implements is void RegisterType(System.Type type). This method defines functionality that is required for all specific rule types. This method is used to register object types for which a specific rule implementation needs to be called by AutoCAD Architecture. The following sections contain some examples for the usage of this method. If a rule implementation needs to be called for all object types, you do not need to call the RegisterType method for all of them. Instead, you can make one call to RegisterType(Autodesk.Aec.SpaceOffsetRulesManager.kAllTypes). Reference:AecSpaceOffsetBaseRule Class namespace Autodesk.Aec.SpaceOffsetRulesManager { public abstract class AecSpaceOffsetBaseRule { protected AecSpaceOffsetBaseRule(); protected void RegisterType(Type type); } } Implementing Specific Offset Rules Common to all rules is a public abstract Apply method, where the return type and arguments are specific to the rule type, which needs to be implemented by each new rule class. The following sections describe the base class of each rule type, and show one example for an implementation of such a rule. Space Rule (SpaceOffsetRulesManager.AecSpaceRule Base Class) A space rule is applied to the whole space, as opposed to all other rule types which are more specific. Space rules are the only type of offset rules that can only be registered once for each standard (once for each of the offset types net, usable, and gross.) Implementing a Space Rule To implement a space rule, you must add a new class that is derived from the SpaceOffsetRulesManager.AecSpaceRule base class. The new class must implement the Apply interface of the base class. It need not call the AecSpaceOffsetRuleBase.RegisterType() method of the base class since it always applies to space objects. The Apply method that each rule needs to implement has the following syntax for the AecSpaceRule class: 1754 | Chapter 36 Spaces
