Geopak - Cross section navigator
Geopak - Cross section navigator
(OP)
Hello-
I have to go through 16 miles of cross sections, 50 feet at a time to determine if the slopes meet certain conditions. Basically, I need to know which sidehill fills are steeper than 8H:1V. I am using Geopak Road, V8 and I know there has to be a faster way than drawing a line representing that slope and moving it around to see if the cross section is 8:1 or steeper. Any help would be appreciated. Thanks!

In Geopak you can use accu draw to help. All you have to do is use your X and Y axis pick a point enter 8, then move the cursor up and type in 1. Then you can copy the line as a cell and use it to check your slopes threw the cross section viewer. There is a draw line command in the cross section viewer that will draw the line on a slope, percent, or decimal eq. hope this helps.

Sam74: I am not sure what you mean by write out the tin file.
Do you mean to open it? I am not so proficient at geopak, I mainly use cross section navigator to determine boring locations and depths. I will give it a go though, and thanks for the help.
Namdac: This is the method I am currently using and I was hoping to find a way to shortcut the process. I also am having problems copying the line I create. I can only use "paste special" and it shows up as a picture. I understand that this has to do with my workstation permissions. Anyway, thanks for the help.
Have a good day!

Thanks for your help, the process was a success. However, the slope analysis tool did not seem competely accurate. For example, the slope over a 5' rise in contours over a distance of 50 feet would show up as a 11.8:1 slope. This concerns me, so I went back to the cross sections and started using the "place cross section line tool" found in the cross section navigator. It is nice, I can draw multiple lines for a slope that varies, at the the rise and run that I specifiy. It is about three times as fast as accu-drawing and pasting triangles. I guess I was hoping I could just somehow process the cross sections and it would identify slopes that met certain criteria. I suppose I would have to write an mdl for that, and I should probably get to the task at hand. Regardless, thanks for all of your help!
