Use Buffer Analysis to show an area around an existing topology. In this case, the

buffer analysis of the power line network topology creates a new polygon topology.

For buffering, you create a new polygon topology from an existing node,

network, or polygon topology and specify a buffer offset.

The buffer offset can be:

■ A positive or negative numeric value

■ An expression

■ A value specified by object data

■ A value linked to an external database record

You can

use negative offset values (page 1541) for polygon topologies only.

TIP You can improve the performance of buffering operations by increasing the

RAM to more than the recommended amount, or by increasing the virtual memory

on your system. This is recommended if you are buffering large topologies.
