InstanceDefinitionGeometry Class

Gets or sets the component status of the model component.

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.

Returns true if the Brep.TryConvertBrep function will be successful for this object

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.

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.

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

true if object can be accurately modified with "squishy" transformations like projections, shears, and non-uniform scaling.

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.

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.

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

Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on.

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 sharable set of information.

Gets the amount of user strings.

Resets the HasId property of the model component to false, if possible.

Resets the HasIndex property of the model component to false, if possible.

Resets the HasName property of the model component to false, if possible.

If this piece of geometry is a component in something larger, like a BrepEdge in a Brep, then this function returns the component index.

Assigns a parent object and a subobject index to this.

Increments the Cyclic Redundancy Check value by this instance.

Actively reclaims unmanaged resources that this instance uses.

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.

Constructs a deep (full) copy of this object.

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.

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.

Passively reclaims unmanaged resources when the class user did not explicitly call Dispose().

Boundingbox solver. Gets the world axis aligned boundingbox for the geometry.

Aligned Boundingbox solver. Gets the plane aligned boundingbox.

Aligned Boundingbox solver. Gets the world axis aligned boundingbox for the transformed geometry.

Aligned Boundingbox solver. Gets the plane aligned boundingbox.

Populates a System.Runtime.Serialization.SerializationInfo with the data needed to serialize the target object.

Gets user string from this geometry.

Gets a copy of all (user key string, user value string) pairs attached to this geometry.

Determines if an object is valid. Also provides a report on errors if this object happens not to be valid.

Locks the component Id property.

Locks the component Index property.

Locks the component Name property.

If possible, converts the object into a form that can be accurately modified with "squishy" transformations like projections, shears, an non-uniform scaling.

Computes an estimate of the number of bytes that this object is using in memory.

For derived classes implementers.

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

Is called when a non-const operation occurs.

Rotates the object about the specified axis. A positive rotation angle results in a counter-clockwise rotation about the axis (right hand rule).

Scales the object by the specified factor. The scale is centered at the origin.

Attach a user string (key,value combination) to this geometry.

Returns the name of the model component type, and then its name and index.

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.

Translates the object along the specified vector.

Translates the object along the specified vector.
