This function calculates the distance between two nodes/points selected by cursor pick or key in node/point number. The program displays a CONTROL OPTION window as shown in Figure 1.6.1. The operation on SELECT BY CURSOR and KEY IN ID is the same as in IDENTIFY NODE function. REJECT LAST allows the user to reject the last selected node. Once two nodes are selected, the program labels the distance and X, Y, Z components between the selected nodes/points on the screen, and also outputs the information in the message window.
