Sub-option TRIANGLE

Selection of this option brings up a heading ELEMENT INFORMATION in the right-hand panel plus certain sub-headings. Two options are available below : INDEX, and QUIT. The first gives a means of selecting the element for which information is required by its number. By default, the element is chosen by cursor.

The following information on the selected element appears:

- index number

- coordinates of centroid

- depth at centroid

- element code (type)

- list of nodes in the element

A marker is placed in each element examined. If a number of them are examined, it may be desirable to erase existing markers in order to be able to spot new markers.
