need quantities from profile

I have an unusual project situation that I need help puzzling out. I have an alignment that has alignments transecting it (see C1). We are adding a structure that will cross these transects and needs to show up on the profile of each one (PP1). At this point I have located each one by drawing it in at the correct elevation and station. I also have a profile along the structure that I have drawn it in at the right depth and spacing by hand (P1). I need to make these hand-draw objects data somehow so it will show up in my other profiles. I will need to generate cut and fill quantities along the length of the structure at some point. I tried using a corridor (first time!) with an assembly drawn to the structure dimensions but can't figure out how to get the info to show up in the other profiles or how to get the quatities. We mostly do commercial site developement so this is way outside my normal work area. Any suggestions?

If you make a block of each structure, you can use Project Object to Profile View (ProjectObjectstoProf).


If you need cut and fill quantities within the horizontal bounds of the structure (?) as though it is providing an outline to use to compare two surfaces: Create the two surfaces and then use the Volumes Dashboard to create a volume surface. Once you've done that, and once you have drawn polylines that represent the bounds of the structure, in the volumes dashboard, use Add Bounded Volume to calc the volume for each structure.


I hope I understood your request correclty.

I would make the stc a surface.


Draw in plan view the stc top and make it a feature line. Offset this feature line .05 units inside with a 0 elv difference. Select the outer feature line, right click and select "Raise/Lower.." Lower this to the stc's depth.


Select them both, right click and select "Add to Surface as Breakline". In the next dislog hit the + button and make a new surface of the structure. Select the outer feature line and add it to the new surface as an outer boundary.


You can now sample this surface for profiles and sections to get an avg end area calc or use surface volumes to get your numbers.
