Used with a reflectorless Total Station. This function is used to shoot a regular, rectangular "pattern" of points across an area. It is useful when periodic measurements of an area are required. Upon starting the function, a query box will ask for two point defining a rectangle, the lower left corner and the upper right corner. For each of these, aim the gun at the corner of the area to be scanned and click "Read". After reading both points, a menu will prompt for several other parameters. Enter the first point number to shoot, as well as any desired description for the points, and both horizontal and vertical increments. These are angle increments, given in seconds. Once all of the above is entered, select "OK" to begin the survey. The total station will now begin turning automatically to the bottom-left corner of the area, and will begin shooting points. Upon reaching the right-hand limit of the area, it will begin a new row of points, starting at the left.
