If you require additional memory for your images, the Raster Extension uses

a temporary swap file. For example, if you insert a 100 MB file, and the Memory

Limit is 8 MB, AutoCAD Map 3D stores the remaining 92 MB in a temporary

file. You can specify where the swap file is created.

You can change the following Raster Extension memory settings:

■ Temporary File Location — The default directory for the temporary swap

files is the Windows temp directory.

TIP For best performance, use a local drive for your temporary swap file. It is

recommended that you do not use the drive where the operating system is

installed as the drive for the swap file unless this is your only local drive.

■ Memory Limit — Specify the maximum amount of computer memory that

AutoCAD Map 3D can use to store image files.

NOTE The more physical RAM you have, the higher you can make your Memory

Limit. The higher the Memory Limit, the less swapping to hard disk occurs and

the faster your images load and display. However, do not allocate all available

physical RAM because doing so slows overall performance.

NOTE Close and restart AutoCAD Map 3D after adjusting these settings.
