Controlling The Size Of The Rendered Image; Controlling Lighting In A Rendered Image - Autodesk 24000-000000-9860 - Revit Architecture - PC User Manual

Rendered image with daylight portals
Daylight portals are useful only for interior views that include sunlight. That is, on the Rendering dialog,
under Lighting, the selected Scheme must be Interior: Sun only, or Interior: Sun + Artificial. (See
Lighting in a Rendered Image
By default, daylight portals are turned off. If a rendered image shows sunlight reflecting off surfaces, and
the sunlight is speckled or splotchy, you may be able to improve the image by turning on daylight portals.
NOTE The use of daylight portals can significantly increase render time.
To turn on daylight portals for an interior view that includes sunlight, use the Render Quality Settings dialog.

Controlling the Size of the Rendered Image

Before rendering a 3D view, you can use the following techniques to control its print size (in pixels) and file
size (in bytes). The width and height of the rendered image display on the Rendering dialog under Output.
Render part of the 3D view: Use a render region, a crop region, or a section box. See
Area to Render
Zoom in or out: When creating a rendered image for screen output, you can zoom in or out to make the
rendered image larger or smaller. See
Change the output resolution: When creating a rendered image for printing, you can specify the image
resolution in DPI (dots per inch). See
NOTE Higher resolution and larger image size increase render time. See
on page 1175.
