Properties (57)

Attributes

Gets or sets the object attributes.

ComponentStatus

ComponentType

Gets the ModelComponentType for this object. Useful in switch statements.

ComponentType

Returns ModelComponentType.ModelGeometry .

CurveGeometry

Returns the underlying curve geometry.

DeletedName

Gets the name of a component that is deleted.

Disposed

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

Document

Gets the document that owns this object.

Geometry

Gets the underlying geometry for this object.
All rhino objects are composed of geometry and attributes.

GripsOn

Gets or sets the activation state of object default editing grips.

GripsSelected

True if grips are turned on and at least one is selected.

GroupCount

Number of groups object belongs to.

HasDynamicTransform

True if the object has a dynamic transformation

HasId

Returns a value indicating whether the component has an ID.

HasIndex

Returns a value indicating whether the component has an Index.

HasName

Returns a value indicating whether the component has a Name.

HasSubobjectMaterials

Will be True if the object contains sub object meshes with materials that are different than the top level object.

HasUserData

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

Gets or sets the ID of the current instance.

Every object has a Guid (globally unique identifier, also known as UUID, or universally unique identifier). The default value is Guid.Empty.
When an object is added to a model, the value is checked. If the value is Guid.Empty, a new Guid is created. If the value is not None but it is already used by another object in the model, a new Guid is created. If the value is not Guid.Empty and it is not used by another object in the model, then that value persists. When an object is updated, by a move for example, the value of ObjectId persists.
This value is the same as the one returned by this.Attributes.ObjectId.

Index

Gets or sets the model component index attribute.

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

IsDocumentControlled

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.

IsHidden

An object must be in one of three modes: normal, locked or hidden. If an object is in normal mode, then the object's layer controls visibility and selectability. If an object is locked, then the object's layer controls visibility by the object cannot be selected. If the object is hidden, it is not visible and it cannot be selected.
