Calculations; Cogo - Pentax R-422VN Instruction Manual

8. CALCULATIONS

The following calculations are available:

• COGO

• 2D SURFACE
• 3D SURFACE & VOLUME
• REM
8.1 Cogo
The 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" File
The R-400V series automatically creates "COGOPoint" file. In the file, the following
coordinates to be used in COGO function, are recorded.
SP
EP
CO
P1
P2
P3
CP
S1
E1
S2
E2
C1
C2
OP
The values recorded in "COGOPoint" are used as an initial value each time these values are
input. 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 SP
and EP which are input at Inverse will be initial values of SE and EP of Distance offset
which 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").
