■ Camera clipping plane : The camera clipping plane defines the depth of the 3D view to render. When
you reduce this clipping plane, Revit Architecture has fewer model elements to process when producing
the rendered image. As a result, the rendering process requires fewer resources, takes less time, and
produces a smaller image file. See
Modifying the Camera Position in a Perspective 3D View on page 113.
■ Section box : A crop region and a render region define a 2D portion of a 3D view to render. A section
box, however, allows you to define a 3D portion of the view to render. By using a section box, you can
omit many model elements from the rendering process, thus reducing the number of calculations and
the processing time required. See
Using a Section Box in a 3D View on page 111.
NOTE When using a section box, be careful about the parts of the building geometry that you exclude from
the view. For example, if a section box excludes an exterior wall for an interior 3D view, sunlight may illuminate
the entire room, affecting the rendered image and increasing render time. See
Render Performance and Lighting
on page 1173.
Specifying the Render Quality
To present a design to clients, you typically want a high quality rendered image. However, high quality
rendered images can be slow to generate. For testing purposes, you may want to generate a draft quality
image quickly. Use the Quality Setting on the Rendering dialog to specify the desired quality for the rendered
image.
Description Relative Render Speed Quality
Render as quickly as possible to get a general idea of the rendered image.
The image contains many artifacts (small inaccuracies or imperfections in
the rendered image). Fastest Draft
Render quickly with a better level of quality and several artifacts. Fast Low
Render with a quality that is usually satisfactory for presentations, with few
artifacts. Medium Medium
Render with high quality that is satisfactory for most presentations, with
very few artifacts. This render quality requires a long time to produce. Slow High
Render with very high quality and a minimum of artifacts. This render
quality requires the most time to produce. Slowest Best
