protected override void InitRules() { // Register the rules with this standard, so the // offset calculation algorithm can call them // for the according boundary type NetRules().AppendBoundingOpeningRule(new BoundingOpeningRuleNet()); // no usable boundary UsableRules().SetSpaceRule(new NullSpace()); GrossRules().AppendBoundingObjectRule(new BoundingObjectRuleGross()); GrossRules().AppendBoundingAdjacencyRule(new BoundingAdjacencyRuleGross()); } } Implementing the AecSpaceOffsetStandard.InitCurrentDatabase() method (Optional) 9 AecSpaceOffsetStandard provides another virtual method that your own standard can implement: AecSpaceOffsetStandard.InitCurrentDatabase(). Since this is not an abstract method of the base class, it can be implemented, but is not mandatory, as opposed to the InitRules() method. It can be used by an area calculation standard to initialize the current drawing with additional data that the rules might require, such as classification definitions or zone styles. If implemented, AutoCAD Architecture will call that implementation every time the standard is assigned to a drawing. The usage of that method is described in an example in "Advanced: Using Classifications in Area Calculation Standards" on page 1762. public class AecSpaceOffsetStandardBasic : AecSpaceOffsetStandard { public AecSpaceOffsetStandardBasic () { // set the name of the standard SetName("Basic"); } // must be overriden protected override void InitRules() { } // can be overriden protected override void InitDatabase(Database* database) { // ...init database with classification definitions or zone styles, etc... } } Reference:AecSpaceOffsetStandard Class The following list shows all members of the AecSpaceOffsetStandard base class: namespace Autodesk.Aec.SpaceOffsetRulesManager { public abstract class AecSpaceOffsetStandard { protected internal AecSpaceOffsetStandard(); protected internal void SetName(string str); protected internal abstract void InitRules(); protected internal AecSpaceOffsetRuleCollection NetRules(); protected internal AecSpaceOffsetRuleCollection UsableRules(); protected internal AecSpaceOffsetRuleCollection GrossRules(); protected internal virtual void InitDatabase(Database* database); protected internal virtual bool IsStandardStyle(ObjectId idStyle); } } Implementing an Area Calculation Standard | 1753
