Note:
It is possible to examine the attributes of a definite point or cell, selected by its ID number. For that, input the ID number of a definite point or cell in the ID field, the attributes of this point or cell will be immediately displayed.

Gauss points can be selected with the help of a special cursor with markers (pyramids). The cursor is dynamically generated so that the apexes of each pyramid touch the point sprite boundary, and the height of the pyramid is fixed.
