Performance Tuning
Performance tuning examines your graphics card and display driver and
determines whether to use software or hardware implementation for features
that support both.
Features that cannot work properly on your system are turned off. Some
features may work but not be recommended for use with your graphics card
or 3D graphics display driver. Enable these features at your own risk. For
information on the options available, see -3DCONFIG.
Memory Tuning
Performance can also be improved by adding memory to your system. This is
especially true when working on larger models.
AutoCAD for Mac requires at least 2 GB of physical memory (RAM) for working
in 2D. For 3D modeling, at least 4 GB of RAM is required.
The size and complexity of a model often defines how efficiently an application
runs. If you notice increased hard drive activity, it means that physical memory
has been exceeded and data is being passed to a swap file (virtual memory).
A swap file is an area on the hard drive that the operating system uses as if it
were physical memory (RAM). The swap file size is basically a limit which
restricts the total virtual size of the AutoCAD for Mac process. A good rule of
thumb for configuring your swap file is three times the amount of physical
memory on your system. This usually sets the limit high enough that AutoCAD
for Mac does not run out of swap space.
Use Viewing Tools
When working in 3D, you'll often want to display different views so that you
can see and verify the 3D effects in your drawing.
Specify 3D Views
You can control the 3D navigation display, projection, and visualization tools.
