DrawContext

Description:
A class that provides drawing functionality for use by servers

Remarks:

The drawing facility of this class is conceptually similar to a low-level graphics API. The functionality operates on a set of geometry primitives such as triangles, lines, and points, which are encoded into a set of vertex and index buffers.

Aside from submission of geometry in buffers, a major part of the drawing process is responding to certain changes in graphics state. For example, users of this class can implement progressive rendering of geometry by testing whether there have been interruptions that should prevent the drawing from being completed.

Name	Return Type	Description
M FlushBuffer(VertexBuffer, Int32, IndexBuffer, Int32, VertexFormat, EffectInstance, PrimitiveType, Int32, Int32)	None	Submits geometry for rendering.
M GetCamera()	Camera	Gets the camera corresponding to the Revit view where rendering takes place.
M GetClipPlanes()	IList<ClipPlane>	Gets the clipping planes for the Revit view where rendering takes place. Clipping planes control the 3D extent of a view and can be set using Section Box in Revit.
M GetClipRectangle()	Rectangle	Gets the clip rectangle for the Revit view where rendering takes place. The clip rectangle is the area currently being redrawn, which may be smaller than the view rectangle.
M GetOverrideColor(Color%)	Boolean	Returns override color that will be applied to geometry during rendering.
M GetOverrideTransparency(Double%)	Boolean	Returns override transparency that will be applied to geometry during rendering.
M GetViewRectangle()	Rectangle	Gets the rectangle that represents the extent (in 2D) of the Revit view where rendering takes place.
M IsAvailable()	Boolean	Checks whether the facilities of this class are available for use in the current scope.
M IsInterrupted()	Boolean	Checks whether the current rendering pass has been interrupted.
M IsTransparentPass()	Boolean	Determines whether the current rendering pass is for transparent objects.
M SetWorldTransform(Transform)	None	Sets the world transformation that will be applied to geometry during rendering.
