Public sealed Class ClipBoundary Inherits DisposableWrapper
public sealed class ClipBoundary : DisposableWrapper;
This .NET class wraps the AcGiClipBoundary ObjectARX struct.
ClipBoundary is used to pass a clip boundary specification from a drawable to the underlying system.
Since boundary clipping closely matches view clipping, it's easiest to consider the parameters in this sense. Imagine that the clip boundary defines a view on the model. To define a view a view direction and a target point are required. These are specified in the main coordinate system, the transformation to the coordinate system should match these values and include any required rotation or twist.
