This keyword is used to gain information about entities. It is especially useful to get the values on particular nodes. But the position of nodes or points are also given in cartesian and cylindrical coordinates (see Figure 3, axyz are the 3 angles around x,y and z, rxyz are the 3 radii around x, y and z). In a second row the sets to which the picked entity belongs are listed. To see details of entities move the mouse pointer over the entity and press one of the following keys, for Nodes n, Elements e, Faces f, Points p, Lines l, Surfaces s, Bodies b, Nurb Surfaces S and for Nurb Lines L. To catch more than one entity with one stroke, type ``a'' before and create a rectangular picking area by pressing two times the ``r'' key. Both strokes define opposite corners of the rectangle. To catch only one entity type ``i'' before. Press ``q'' to quit the command.

It is also possible to measure distances between two pixels on the screen. Just press the key ``w'' on the positions of the two pixels. The distance is calculated in the scale of the displayed geometry.
