Defining the View Area
can render part of a 3D view. You might use this strategy for the
When you click Render, Revit Architecture renders
only the specified part of the building model.
To define the view area
to render, use one or more of the following methods:
- Crop region:
Open the 3D view, and apply a crop region to define the area to
Cropping a View.
To check or change the size of the cropped view, select the crop
region, and click Modify Cameras tabCrop panelSize
- Render region:
the Rendering dialog,
and click Region. In the 3D view, Revit Architecture displays the render
region boundary. Select the render region, and use the blue grips
to adjust its size. For orthographic views, you can also drag the render
region to move its location in the view. If the view uses a crop region,
the render region must reside within the crop region boundaries.
- 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.
- 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.
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
