The command uses the X,Y from the selected entities and calculates the Z from a surface model that is stored in a grid (.grd) or triangulation (.flt, .tin) file. For example, this command could be used to generate points representing key locations of design features for stakeout. Choose the lines and arcs of your design with this command to specify the PC's, PT's and endpoints. The results are stored in the current coordinate (.CRD) file and could be transferred to an electronic field book.
