8. CALCULATIONS8.1 CogoThe following calculations are available:•COGO•2D SURFACE•3D SURFACE & VOLUME•REMThe following COGO functions are available:•Inverse•Point Coordinates•Circle Radius•Line-Arc intersection•Line-Line intersection•Arc-Arc intersection•Distance offset•Point distance offset•Arc distance offset"COGOPoint" FileThe R-400 series automatically creates“COGOPoint”file. In the file the followingcoordinates to be used in GOGO function are recorded.SP Station PointEP End PointCO CoordinatesP1 Point 1P2 Point 2P3 Point 3CP Center PointS1 Start point 1E1 End point 1S2 Start point 2E2 End point 2C1 Center point 1C2 Center point 2OP Observation PointThe values recorded in "COGOPoint" are used as an initial value each time these values areinput. These values are updated when the function which uses these values is carried out.For instance, if you carry out Inverse, then carry out Distance offset later, the values of SPand EP which are input at Inverse will be initial values of SE and EP of Distance offsetwhich is carried out later. If you wish to input the initial value in advance, edit it by using“VIEW&EDIT of EDIT THE RECT. DATA.(Refer to“5.3 Edit the Data”).62
