Find Border creates lines between values less than a given threshold and values greater than the threshold. The output is a binary image (contains only 1's and 0's). The output image may then be used in the modeling process by the 2D Object Finder to create polygons on 2D sections.
For notes on how to approach the Modeling process, see 3D Modeling Strategies.
The controls for selecting the input file, output file, and region to process are shared with many other Priism applications and are described elsewhere. The controls specific to Find Border are described below.

Find Border will create a line between values greater than and values less than the value in this field.
Find Border accepts the command-line arguments described in
Region.html, including the
-prompt option to operate in a text-only mode. To set
the threshold level from the command line, include
-threshold=level
in the options where level should be replaced by the intensity threshold value.
