Hello!
Could some one please help me with this:
I have an existing survey surface, and I want to know how much cubic yard of materials to fill up from the bottom to elevation 876. See attached image for detail. Here is what i am going to do and please correct me if my way is right way to do or not:
- i will create a surface of the fill area (from bottom cotours up to el 876) then do a volume surface bwt existing ground surface and the new fill area surface to get the volume of it? Is this a right way to do?
Thanks and Regards.
If the finished surface is all at 876 then extract the 876 contour and use that as a breakline/boundary in a new surface then volume surface with EG as base and 876 surface as comparison.
OR
draw a rectangle at 876, create a surface from it and use this as the comparison surface (possible easier as no triangles to trim out on concave areas)
OR
You could also draw a rough pline around the 876 contour and run reportsurfboundedvolume with the pline as the boundary and specify a datum of 876.
Incidentally at the top left of the screendump the contours appear to drop down to around 873.5 in which case this will be calculated with a vertical "cookie cut edge" which may or may not affect the volume greatly

"draw a rectangle at 876, create a surface from it and use this as the comparison surface (possible easier as no triangles to trim out on concave areas)"
You meant: draw a rough pline around 876, create a surface from this contour line and do a volume surface with EG as base and surface 876 as comparation? i am not understanding? Keep in mind that i want to know the volume of fill material FROM THE BOTTOM OF THE EG surface (el 873) UP TO EL 876?
Please help!
Please see attached for better understanding my question. Thanks,
Yup - I would do the second option.
Draw a feature line, elevation = 876 around your area of interest but slightly larger.
Create a surface
Select the featureline, right click and add to surface as breakline.
Analyze/Volumes, selecting your EG as the base and your 876 elevation surface as the compare. Ignore any cut values.
