Return Value
True if the DrawContext is available for rendering, false otherwise.Remarks
This class can perform drawing operations and access the state of parameters related to drawing only in lock-step with rendering inside of Revit. As a consequence, the facilities of this class are not available for use outside of the scope determined by the callback RenderScene(View, DisplayStyle). Certain methods of other DirectContext3D objects, e.g., VertexBuffer::Map() are similarly restricted by the same scope.
