public sealed class InstanceDefinition

The InstanceDefinition type exposes the following members.

Properties
  NameDescription
Public propertyArchiveFileStatus
Returns the archive file status of a linked instance definition.
Public propertyComponentStatus
Gets or sets the component status of the model component.
(Inherited from ModelComponent.)
Public propertyComponentType (Overrides InstanceDefinitionGeometryComponentType.)
Public propertyDeletedName
Gets the name of a component that is deleted.
(Inherited from ModelComponent.)
Public propertyDescription
Public propertyDisposed
Indicates if this object has been disposed or the document it originally belonged to has been disposed.
(Inherited from CommonObject.)
Public propertyHasId
Returns a value indicating whether the component has an ID.
(Inherited from ModelComponent.)
Public propertyHasIndex
Returns a value indicating whether the component has an Index.
(Inherited from ModelComponent.)
Public propertyHasName
Returns a value indicating whether the component has a Name.
(Inherited from ModelComponent.)
Public propertyHasUserData
Gets true if this class has any custom information attached to it through UserData.
(Inherited from CommonObject.)
Public propertyId
Public propertyIdIsLocked
Returns a value indicating whether the component ID is already locked.
(Inherited from ModelComponent.)
Public propertyIndex
Index of this instance definition in the index definition table.
Public propertyIndexIsLocked
Returns a value indicating whether the component Index is already locked.
(Inherited from ModelComponent.)
Public propertyIsComponentStatusLocked
The component status itself can be locked. This returns an indication.
(Inherited from ModelComponent.)
Public propertyCode exampleIsDeleted
Public propertyIsDocumentControlled
If true this object may not be modified. Any properties or functions that attempt to modify this object when it is set to "IsReadOnly" will throw a NotSupportedException.
(Inherited from CommonObject.)
Public propertyCode exampleIsReference
An object from a work session reference model is reference a reference object and cannot be modified. An object is a reference object if, and only if, it is on a reference layer.
Public propertyIsSystemComponent
True if this model component is a system constant.

An incomplete list of system constant model components is below:

  • ON_ModelComponent::Unset

  • ON_InstanceDefinition::Empty

  • ON_Linetype::Unset
  • ON_Linetype::Continuous
  • ON_Linetype::ByLayer
  • ON_Linetype::ByParent

  • ON_Layer::Unset
  • ON_Layer::Default

  • ON_TextStyle::Unset
  • ON_TextStyle::Default
  • ON_TextStyle::ByLayer
  • ON_TextStyle::ByParent

  • ON_DimStyle::Unset
  • ON_DimStyle::Default
  • ON_DimStyle::DefaultInchDecimal
  • ON_DimStyle::DefaultInchFractional
  • ON_DimStyle::DefaultFootInchArchitecture
  • ON_DimStyle::DefaultMillimeterSmall
  • ON_DimStyle::DefaultMillimeterLarge
  • ON_DimStyle::DefaultMillimeterArchitecture
(Inherited from ModelComponent.)
Public propertyIsTenuous
Public propertyIsValid
Tests an object to see if it is valid.
(Inherited from CommonObject.)
Public propertyLayerStyle
Public propertyName
Public propertyNameIsLocked
Returns a value indicating whether the component Name is already locked.
(Inherited from ModelComponent.)
Public propertyObjectCount
Number of objects this definition uses. This counts the objects that are used to define the geometry. This does NOT count the number of references to this instance definition.
Public propertySkipNestedLinkedDefinitions
Controls how much geometry is read when a linked InstanceDefinition is updated.
Public propertySourceArchive
Public propertyUpdateType
Public propertyUrl
The hyperlink URL that is executed when the UrlDescription hyperlink is clicked on in the Insert and Block UI
Public propertyUrlDescription
The URL description displayed as a hyperlink in the Insert and Block UI
Public propertyUserData
List of custom information that is attached to this class.
(Inherited from CommonObject.)
Public propertyUserDictionary
Dictionary of custom information attached to this class. The dictionary is actually user data provided as an easy to use sharable set of information.
(Inherited from CommonObject.)
