Parameters

vertexBuffer
Type: Autodesk.Revit.DB.DirectContext3D VertexBuffer
The vertex buffer that contains vertex data.
vertexCount
Type: System Int32
The number of vertices in the vertex buffer.
indexBuffer
Type: Autodesk.Revit.DB.DirectContext3D IndexBuffer
The index buffer that contains indices into the vertex buffer.
indexCount
Type: System Int32
The number of indices in the index buffer.
vertexFormat
Type: Autodesk.Revit.DB.DirectContext3D VertexFormat
The format of the vertices in the vertex buffer.
effectInstance
Type: Autodesk.Revit.DB.DirectContext3D EffectInstance
The effect instance to be used for drawing this piece of geometry.
primitiveType
Type: Autodesk.Revit.DB.DirectContext3D PrimitiveType
The type of geometry primitive used in the index buffer.
start
Type: System Int32
The first index to use for drawing.
primitiveCount
Type: System Int32
The number of primitives to draw.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions 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.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions ArgumentOutOfRangeException A value passed for an enumeration argument is not a member of that enumeration
Autodesk.Revit.Exceptions 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.
