Compute FingerPrint of the Entity.

Creates a new catchment given a name, style id, reference surface id, polyline.

Creates a copy of the catchment and assigns it to a new group. This is equivalent to a Copy Catchment To Group operation To be consistent with the user interface, the user shall change the name of the new catchment (if desired) after the copy operation has been performed.

Gets the ObjectIdCollection of all CatchmentLabels for the Catchment.

Gets the ObjectIdCollection of all FlowSegmentLabels for the Catchment.

Get the FlowPath of the Catchment.

For Data Shortcut reference entity (IsReferenceObject == true), gets the entity's reference information.

Sets the FlowPath of the Catchment from an array of points

Sets the FlowPath of the Catchment from another flow path.

Gets/Sets the Antecedent Wetness

Gets the Application. Not currently implemented.

Gets the 2d Area of the boundary

Gets the 2d boundary polyline

Gets/Sets the 3d boundary polyline

Gets the containing group Id of the catchment area

Gets/Sets the Curve Number

Gets or sets the Entity object's description.

Gets the discharge point of the catchment area

Gets the Entity object's display name.

Gets the Document. Not currently implemented.

Gets the exclusionary flag of the catchment area

Gets or sets FingerPrint of the Entity.

Gets the folder ObjectId of the Entity Returns ObjectId::Null if the Entity is located in root folder

Gets the hydrologically most distant length of the catchment area

Gets the hydrologically most distant point of the catchment area

Gets/Sets the Soil Group

Gets/Sets the Impervious Area

For reference object (IsReferenceObject == true), it will try to get its source entity while opening a drawing. This indicates whether the reference object has source entity.

Gets whether the Entity is a reference object. A reference object is located in another drawing, and linked using a data shortcut or Vault. If the entity is native to the current drawing this property returns false; if it is being referenced via data shortcuts or AutoCAD Vault it returns true.

For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is stale.

For reference objects (IsReferenceObject == true), gets whether the Entity is a reference subobject. For example, when iterating through the structure of a pipe network referenced from another drawing, this property is true for each entity.

For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is valid.

Gets whether the style is used by other objects in the current drawing.

Gets/Sets the mannings coefficient for the catchment area

Gets or sets the Entity object's name.

Gets the 2d Perimeter of the boundary polyline

Gets the reference pipe network for the catchment area

Gets the reference pipe network for the catchment area

Gets/Sets the reference pipe network structure id for the catchment area

Gets the reference pipe network structure name for the catchment area

Gets/Sets the reference surface for the catchment area

Gets the reference surface for the catchment area

Gets/Sets the runoff coefficient for the catchment area

Gets or sets whether to show tooltips for the Entity.

Gets / Sets the catchment style

Gets or sets the Entity object's style name.

Gets the time of concentration for the catchment area

Gets/Sets the time of concentration method for the catchment area

Gets/Sets the Unconnected Impervious Area Percent
