Methods
  NameDescription
Public methodClearPropertyOverrides
Clears all overriden properties for this annotation
(Inherited from AnnotationBase.)
Public methodComponentIndex
If this piece of geometry is a component in something larger, like a BrepEdge in a Brep, then this function returns the component index.
(Inherited from GeometryBase.)
Protected methodConstructConstObject
Assigns a parent object and a subobject index to this.
(Inherited from CommonObject.)
Public methodStatic memberCreate
Creates a Leader geometry object
Public methodStatic memberCreateWithRichText
Creates a Leader geometry object
Public methodDispose
Actively reclaims unmanaged resources that this instance uses.
(Inherited from CommonObject.)
Protected methodDispose(Boolean)
For derived class implementers.

This method is called with argument true when class user calls Dispose(), while with argument false when the Garbage Collector invokes the finalizer, or Finalize() method.

You must reclaim all used unmanaged resources in both cases, and can use this chance to call Dispose on disposable fields if the argument is true.

Also, you must call the base virtual method within your overriding method.

(Inherited from CommonObject.)

In Rhino for Windows, this member is overridden by Dispose(Boolean).
Public methodDuplicate
Constructs a deep (full) copy of this object.
(Inherited from GeometryBase.)
Public methodDuplicateShallow
Constructs a light copy of this object. By "light", it is meant that the same underlying data is used until something is done to attempt to change it. For example, you could have a shallow copy of a very heavy mesh object and the same underlying data will be used when doing things like inspecting the number of faces on the mesh. If you modify the location of one of the mesh vertices, the shallow copy will create a full duplicate of the underlying mesh data and the shallow copy will become a deep copy.
(Inherited from GeometryBase.)
Public methodEnsurePrivateCopy
If you want to keep a copy of this class around by holding onto it in a variable after a command completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can call this function as many times as you want.
(Inherited from CommonObject.)
Public methodEquals (Inherited from Object.)
Protected methodFinalize
Passively reclaims unmanaged resources when the class user did not explicitly call Dispose().
(Inherited from CommonObject.)
Public methodCode exampleGetBoundingBox(Boolean)
Boundingbox solver. Gets the world axis aligned boundingbox for the geometry.
(Inherited from GeometryBase.)
Public methodCode exampleGetBoundingBox(Plane)
Aligned Boundingbox solver. Gets the plane aligned boundingbox.
(Inherited from GeometryBase.)
Public methodGetBoundingBox(Transform)
Aligned Boundingbox solver. Gets the world axis aligned boundingbox for the transformed geometry.
(Inherited from GeometryBase.)
Public methodGetBoundingBox(Plane, Box)
Aligned Boundingbox solver. Gets the plane aligned boundingbox.
(Inherited from GeometryBase.)
Public methodGetDimensionStyle
Return the proper dimension style from which to get properties for this annotation object If this object has style overrides, those will be included in the returned dimension style and the style will be updated to include the current state of the parent style for non-overridden fields
(Inherited from AnnotationBase.)
Public methodGetHashCode (Inherited from Object.)
Public methodGetObjectData
Populates a System.Runtime.Serialization.SerializationInfo with the data needed to serialize the target object.
(Inherited from CommonObject.)
Public methodGetType (Inherited from Object.)
Public methodGetUserString
Gets user string from this geometry.
(Inherited from GeometryBase.)
Public methodGetUserStrings
Gets a copy of all (user key string, user value string) pairs attached to this geometry.
(Inherited from GeometryBase.)
Public methodIsPropertyOverridden
Returns true if a property is overridden
(Inherited from AnnotationBase.)
Public methodIsValidWithLog
Determines if an object is valid. Also provides a report on errors if this object happens not to be valid.
(Inherited from CommonObject.)
Public methodMakeDeformable
If possible, converts the object into a form that can be accurately modified with "squishy" transformations like projections, shears, an non-uniform scaling.
(Inherited from GeometryBase.)
Protected methodMemberwiseClone (Inherited from Object.)
Public methodMemoryEstimate
Computes an estimate of the number of bytes that this object is using in memory.
(Inherited from GeometryBase.)
Protected methodNonConstOperation
For derived classes implementers.

Defines the necessary implementation to free the instance from being const.

(Inherited from CommonObject.)

In Rhino for Windows, this member is overridden by NonConstOperation.
Protected methodOnSwitchToNonConst
Is called when a non-const operation occurs.
(Inherited from GeometryBase.)
Public methodRotate
Rotates the object about the specified axis. A positive rotation angle results in a counter-clockwise rotation about the axis (right hand rule).
(Inherited from GeometryBase.)
Public methodScale
Scales the object by the specified factor. The scale is centered at the origin.
(Inherited from GeometryBase.)
Public methodSetBold
(Inherited from AnnotationBase.)
Public methodSetFacename
(Inherited from AnnotationBase.)
Public methodSetItalic
(Inherited from AnnotationBase.)
Public methodSetOverrideDimStyle
Set a style including overrides for this annotation object. The DimensionStyle OverrideStyle must have the override fields marked as overridden and must have it's Id set to nil. Use DimensinoStyle.SetFieldOverride(Field field) and related functions to manage override settings. To override a field, the field value must be set and the field must be marked as an override. The DimensionStyle passed in here must not be in the dimstyle table
(Inherited from AnnotationBase.)
Public methodSetRichText
(Inherited from AnnotationBase.)
Public methodSetUnderline
(Inherited from AnnotationBase.)
Public methodSetUserString
Attach a user string (key,value combination) to this geometry.
(Inherited from GeometryBase.)
Public methodToString (Inherited from Object.)
Public methodTransform
Transforms the geometry. If the input Transform has a SimilarityType of OrientationReversing, you may want to consider flipping the transformed geometry after calling this function when it makes sense. For example, you may want to call Flip() on a Brep after transforming it.

Public methodTranslate(Vector3d)
Translates the object along the specified vector.
(Inherited from GeometryBase.)
