Render presets allow you to define the settings that should be used when rendering 3D objects on screen or during the output of a layout. There are two types of render presets: standard and custom. The five standard render presets (Draft, Low, Medium, High, and Presentation) cannot be modified as they are defined with the application. Custom render presets are stored in the “ACAD_RENDER_SETTINGS” named dictionary as MentalRayRenderSettings objects.
A second named dictionary, “ACAD_RENDER_PLOT_SETTINGS”, is used to store a copy of a render preset so it can be assigned to a Viewport or PlotSettings object.
This example lists the render presets that are stored in the current drawing.

This example creates or edits a render preset named MyPreset. A helper function named GetDefaultRenderPreset is defined and used to get the recreate the settings of one of the standard render presets.
