Create Vertical Alignment: With an ASCII file and COGO
To create the Vertical Alignment through COGO, search for "Profile Commands" using GEOPAK Road HELP. That section explains several ways to create the Vertical Alignment non-graphically. If the Vertical Alignment has already been designed by another software or if you've already laid out the alignment on paper and the VPI information is known...that would be a way to store the vertical alignment in GEOPAK.
The syntax for creating an ASCII text file to load into COGO appears below:
STORE PROFILE VERT2 VPI 1 S 10000 E 2259.54 VPI 2 S 10517 E 2274 L 300 VPI 3 S 10871 E 2263 L 200 VPI 4 S 11198 E 2284 L 200 VPI 5 S 11612 E 2284 L 150 VPI 6 S 11742 E 2279 L 100 VPI 7 S 11976 E 2282 L 290 VPI 8 S 12395 E 2279 L 150 VPI 9 S 12574 E 2267 L 150 VPI 10 S 12931 E 2263 L 137 VPI 11 S 13077 E 2252 L 155 VPI 12 S 13230 E 2250.97 END PROFILE
Create an ASCII text file similar in format to one shown above and save the file with the traditional COGO naming convention, where the name of the file ends with the job number and the extension ends with .i(operator code). For example I want to load this file into job261.gpk and my operator code is SP. I'm saving the file as DEMO261.iSP. I could have named the first part of the name (ASCII) anything, but in order for the GPK file to see the file, it must end as described, [name]261.i[oc]
NOTE: Always press ENTER at the end of the last line of the ASCII file (to leave a blank line at the bottom). For example, press ENTER after typing END PROFILE.
Invoke COGO and load the input file as shown below. Use the COGO pulldowns, File > Load and select the file, press OK.
The file is still only in memory. To read and process and store the profile, use the COGO pulldowns, Edit > Read All.
The Profile "VERT2" is now stored into the GPK file as shown below:
