COGO
The COGO menu is found next to the Draw menu in MAP view. Below you will find each feature described.
Inverse (I):
Inverse command Inverses and presents the bearing and distance between point numbers. It has the added benefit that
the previous point inversed becomes the backsight, and the current point inversed becomes the occupied point, allowing
you to sequence directly into the Traverse or Sideshot commands. (Use angle code 7 to turn an angle right from the
backsight to the foresight.) The "snaps" are available in inverse, so you can calculate the distance from a point to a line
by "snapping" to endpoint, intersect, perpendicular or nearest (as shown in Align Building command in Draw).
Traverse (T) (also TR):
Similar to the Sideshot command, the Traverse command will “move up” to the last point traversed, holding the
previous occupied points as the backsight. Exit with Esc.
Sideshot (SS) (also S):
This allows for sideshots from any point that is “occupied” by use of the inverse command. For
example, if you inverse from 126 to 150, you are “on” 150 and backsighting 126. Then at the prompt "Cmd: Inverse –
Tr/Ss/Pick point or point No:", you can enter S for Sideshot. The first prompt is the Angle-Bearing Code:
Sideshot-eXit/I/Tr/H/Angle-BC(1-7)<7>, which can be any of the following:
1-NE (0 through 90 if degrees, 0 through 100 if gons/grads)
2-SE (same as above)
3-SW (same as above)
