Parameters

Parameter	Type	Description
vertexBuffer	VertexBuffer	The vertex buffer that contains vertex data.
vertexCount	Int32	The number of vertices in the vertex buffer.
indexBuffer	IndexBuffer	The index buffer that contains indices into the vertex buffer.
indexCount	Int32	The number of indices in the index buffer.
vertexFormat	VertexFormat	The format of the vertices in the vertex buffer.
effectInstance	EffectInstance	The effect instance to be used for drawing this piece of geometry.
primitiveType	PrimitiveType	The type of geometry primitive used in the index buffer.
start	Int32	The first index to use for drawing.
primitiveCount	Int32	The number of primitives to draw.

Return Value

Exceptions

Exception	Condition
ArgumentException	A change in the graphics state has made the vertex buffer vertexBuffer invalid for rendering. -or- A change in the graphics state has made the index buffer indexBuffer invalid for rendering. -or- A change in the graphics state has made the vertex format vertexFormat invalid for rendering. -or- A change in the graphics state has made the effect instance effectInstance invalid for rendering. -or- The vertex format vertexFormat and the effect instance effectInstance do not match.
ArgumentNullException	A non-optional argument was null
ArgumentOutOfRangeException	A value passed for an enumeration argument is not a member of that enumeration
InvalidOperationException	This DrawContext is not available because Revit is not currently rendering. In general, this DrawContext must be used in the scope of the RenderScene() callback of IDirectContext3DServer.
