About Memory and Storage Requirements for Plotting to Temporary Files

Specifies settings that can affect performance of plotting large raster format files.

Large raster objects are expensive to plot because the files can be large. A 400 أ—
400 raster uses four times as much memory as a 200 أ— 200 raster. Color depth can also
use a lot of memory, depending on the file format. True Color can use up to 32 times
more memory than bitonal rasters. Keep memory issues in mind when configuring a large
raster plot.

When you plot a large drawing or a large raster image, several types of temporary
files may be created. Make sure you have enough space on your disks for temporary
files in the following areas:

  • Operating system (OS) temporary directory: The operating system uses a directory for temporary files. This location is determined
    by the TEMP environment variable on the Windows operating system.
  • Program temporary directory: Temporary files for the program are stored in a temporary file directory. This directory
    is specified in Options on the Files tab.
  • System directory: The system spooler uses this directory. When a plot is spooled, a copy of the data
    may be in this directory temporarily.
  • Swap space: Windows uses this swap space when an operation uses more RAM than is available.
    You can configure the location of Windows swap space in the System dialog box in the
    Windows Control Panel. Allow at least five times as much swap space as RAM. For example,
    ACIS models or large raster images need more swap space.

Depending on the situation, you may need thousands of megabytes of disk space for
these temporary files.
