You could create a surface from your points and the use a surface profile for your corridor baseline profile.
You don´t need to do the 3D poly by hand.
If you already got the points and the numbers are increasing, just choose to draw a 3D poly and then in the transparent Commands choose POINT NUMBER , give 1-10000 and Civil connects all points for you.
I managed to create points from the the Pipe Inverts and import to the plan view. I connected node to node to create my FL. When I checked the elevations in Editor just to assure that the FL was correct every fifth or so elevation was wrong. Some by This some by ten feet. Lesson learned in creating a feature line in this manner is to isolate only the points you are connecting. I thin,k even though I am snapping to the nodes, that somehow I am picking up existing ground elevations from the data link surface. Also here were two separate, but sequential, pipe networks that I created separately. After I adjusted elevations in the editor and I attempted to join them the elevations changed on the feature line. Fresh mind this morning. Starting over. I am reviewing Johns link first. T
Thanks for all the input. I rarely use anything more than just building an existing surface so I am wandering in unknown territory.
Houston we have cross sections of the trench with the proposed pipe. Yesterday I ran a volume report betwwen my Existing and my Proposed trench surface. 43560 cubic yards of cut, 43 cu. yds.of fill. My OCD wants to figure out why the heck I have any fill at all but I'm going to let it slide. Did a quick average LxDxW computation and the volume report is very believable. Ran cross sections last nite. Actually went home and let the machine run because it did not want to 11,000 feet of sections at every 50'. The sections look great and there is my pipe running right thru each one. NEW PROBLEM. Section volume report. How do I add the pipe to the volume report reflects the fill with the pipe. The fill should be a different number than the cut cause there is a 48" pipe in that trench. I know how to hand calculate but would love to have it reflected in the report. Thanks.
Yes this can all be quite fustrating. Each job starts with different types of data and you need to propose a whole bunch of different improvements. Unfortunately there is no book with a 'do this if you have these and want those' approach. I think we have all tried a few procedures until we hone one method we feel most efficient with. It is also tough for us at times to provide help since we don't always have all of the background information. There are very different needs for and engineer who needs to widen 100' of road and one who needs to design 10 miles of highway.
You have a lot of great tips, tricks and procedures here. Chuck them in your own toolbox and browse this forum for a few minutes each day to identiify other methods that may help. There are a ton of great ideas, tips and fixes here.
Now back to the real issues. More here on the pipe trench corridor.
Yes you need to check all of your fline elevations. Generally speaking things work well but sometimes the elevations get a little wierd.
The Pipe2pline link that tore.lindel posted looks like it could be useful as well.
Good luck and don't stress. The help is here for the asking.
It's been a while since I've done this...
Did you sample the pipe network along with the surface(s) in the cross sections? If not do so and see if a material takeoff will subtract the pipe.
i would think I did John since the pipe is in the xsections??? Moving on I have generated a volume report. If you right click on the report it says I can export to Microsoft Excel. Is this possible. I can generate an XML but really need an excel file if possible.
