Adding the AecSpaceOffsetStandard.InitRules() method 7 After registering the area calculation standard plug-in name, you must add the new AecSpaceOffsetStandardBasic.InitRules() method to your class. The method will override the abstract AecSpaceOffsetStandard.InitRules() interface. AutoCAD Architecture will call that interface to register all individual offset rules you are going to implement. As this method is abstract, it must be implemented by your custom standard class. See the following example for instructions: public class AecSpaceOffsetStandardBasic : AecSpaceOffsetStandard { public AecSpaceOffsetStandardBasic () { SetName("Basic"); } protected override void InitRules() { // register rules } } Registering rules with InitRules() 8 The rule objects of the standard must be registered with the 3 different offset boundaries (net, usable, and gross). The AecSpaceOffsetStandard base class has 3 containers for these rule sets, which the derived class can add new rule instances to. These containers can be referenced with the following methods: ■ AecSpaceOffsetStandard.NetRules() ■ AecSpaceOffsetStandard.UsableRules() ■ AecSpaceOffsetStandard.GrossRules() For information about implementing the individual rules in a standard, see "Implementing Offset Rules" on page 1754. Each of these calls will return a reference to an object of the Autodesk.Aec.SpaceOffsetRulesManager.AecSpaceOffsetRuleCollection class, which exposes functions to register the different rule types. These objects are maintained and used by AutoCAD Architecture. The following example shows how to register rules with the 3 different offset types: public class AecSpaceOffsetStandardBasic : AecSpaceOffsetStandard { public AecSpaceOffsetStandardBasic () { SetName("Basic"); } 1752 | Chapter 36 Spaces
