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. |
