Two Way Control

This routine calculates section and 1/4 section corners by two way control. Enter the point numbers for Point A and B. These numbers can be entered in manually or picked from the screen by selecting the Pick radial button at bottom right. In a like manner, the Record Chainages from A to X and from A to B can be entered manually or by using the Pick radial button to pick from the screen. After selecting OK, a dialog box will display where the Point number, description and elevation can be edited. The point default settings determine the available data for editing. For example, if the option for Automatic Point Numbering is turned off in the Point Defaults, then the field for the point number will be grayed out. If elevations are turned off in the point defaults, then the elevation field with be grayed out. This also applies to the description of the point as well. GLO is an acronym for Government Land Office.
