AutoCAD Map 3D reserves 25%
of the total physical memory (RAM) on your system for inserting
images with the Raster Extension. If you increase the
default amount, more of the physical memory is used for images and
less is available for other operations in AutoCAD Map 3D and for other
applications you might be running.
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.
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
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.
and restart AutoCAD Map 3D after adjusting these settings.
