Layer Properties

Gets or sets the display color for this layer.

Gets or sets the status of the layer.

Returns Layer.

Gets the name of a component that is deleted.

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

Gets the full path to this layer. The full path includes nesting information.

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 this layer object. You typically do not need to assign a custom ID.

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

Gets or sets the IGES level for this layer.

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.

Returns true if the layer is the current layer.

Gets a value indicating whether this layer has been deleted and is currently in the Undo buffer.

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.

Gets or sets a value indicating whether this layer is expanded in the Rhino Layer dialog.

Gets or sets a value indicating the locked state of this layer.

Gets a value indicting whether this layer is a referenced layer. Referenced layers are part of referenced documents.

Returns true if the layer is a parent layer of the layer tree from a linked instance definition or the layer tree from a worksession reference model.

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.

Gets or sets the global visibility of this layer.

Return true if the layer is visible in user interfaces that display layers. Returns false if the layer not visible in user interfaces. This is a runtime property that does not persist in .3dm files. This property is also used by the Layers panel to filter layers.

Gets or sets the line-type index for this layer.

Gets or sets the model visiblity of this layer.

Gets or sets the model persistent visibility of this layer. The persistent viability setting is used for layers whose visibility can be changed by a parent layer. In this case, when a parent layer is turned off, then child layers are also turned off. The persistent visibility setting determines what happens when the parent is turned on again.

A value identifying the model that manages this component.

Gets or sets the name of this layer.

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

Gets the ID of the parent layer. Layers can be organized in a hierarchical structure, in which case this returns the parent layer ID. If the layer has no parent, Guid.Empty will be returned.

Gets or sets the global persistent visibility setting for this layer.

Gets and sets the initial per viewport visibility of this layer in newly created detail views.

Gets or sets the plot color for this layer.

Gets or sets the weight of the plotting pen in millimeters. A weight of 0.0 indicates the "default" pen weight should be used. A weight of -1.0 indicates the layer should not be printed.

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

Gets or sets the RenderMaterial for objects on this layer that have MaterialSource() == MaterialFromLayer. A null result indicates that no RenderMaterial has been assigned and the material created by the default Material constructor or the RenderMaterialIndex should be used.

Gets or sets the index of render material for objects on this layer that have MaterialSource() == MaterialFromLayer. A material index of -1 indicates no material has been assigned and the material created by the default Material constructor should be used.

Runtime index used to sort layers in layer dialog.

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.
