InstanceDefinitionGeometry Properties

Gets or sets the component status of the model component.

Returns InstanceDefinition.

Gets the name of a component that is deleted.

Gets or sets the description of the definition.

Indicates if this object has been disposed or the document it originally belonged to has been disposed.

Returns a value indicating whether the component has an ID.

Returns a value indicating whether the component has an Index.

Returns a value indicating whether the component has a Name.

Gets true if this class has any custom information attached to it through UserData.

Gets or sets the ID of the current instance.

Returns a value indicating whether the component ID is already locked.

Gets or sets the model component index attribute.

Returns a value indicating whether the component Index is already locked.

When a component is in a model as part of the information required for a linked instance definition, this value identifies the linked instance definition reference model.

The component status itself can be locked. This returns an indication.

true if the component is deleted. Deleted components are kept by the document for undo purposes.

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.

Returns true if this instance definition is linked to an external source archive, that is, if its UpdateType is Linked or LinkedAndEmbedded.

Gets a value indicting whether this component is a referenced component. Referenced components are part of referenced documents.

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

Tests an object to see if it is valid.

Specifies how model components (layers, materials, dimension styles, etc.) from linked instance definition files appear in the active model.

A value identifying the model that manages this component.

Gets or sets the name

Returns a value indicating whether the component Name is already locked.

When a component is in a model for reference, this value identifies the reference model.

This property applies when an instance definition is linked. If true, when reading the file that defines the content of the linked instance definition, skip any linked instance definitions found in that file. If false, when reading the file that defines the content of the linked instance definition, recursively load linked instance definitions found in that file.

Gets the full file path for linked instance definitions.

Gets the source archive path for linked instance definitions relative to the file that contains this definition. Empty if the definition is not linked or no relative path is stored.

Gets the unit system of the instance definition. If the instance definition was imported from another 3dm file, the unit system may differ from that of the document.

Gets the relationship between this instance definition's geometry and the source archive that contains the original definition.

Gets or sets the URL or hyperlink of the definition.

Gets or sets the description of the URL or hyperlink of the definition.

List of custom information that is attached to this class.

Dictionary of custom information attached to this class. The dictionary is actually user data provided as an easy to use shareable set of information.

Gets the amount of user strings.
