# Tin Volume Surface

300 Views, 5 Replies

Can anyone explain for me the idea behind Tin Volume Surface?

I have a pit/hole as base surface and the existing ground on the top is the comparison surface.

I want to calculate the volume of the hole (or the fill).

Using the Volume Utilities I got the result.

But what is the use of Tin Volume Surface?

Hi,

>> But what is the use of Tin Volume Surface?

For displaying analyses,

E.g. to colorize where surface1 is above surface2 and where lower + the amount of higher and lower. Create a surfacestyle with elevation analyses and that's it.

Or to know where is the exact position of the edge when surface1 cuts through surface2 ==> it's the contour line for elevation 0.00 in the volume surface.

Thanks!

But the resulting object is just a flat surface and not a volume or a "solid" representing amount of the "earthwork"!

My understanding was that the two surfaces were like the shell and the Tin Volume then would be the core.

Tin volume Surface is just a color scheme in 2D!

Am I correct?

Hi,

Yes and no, it represents the core, but not at it's elevation.

E.g. if the first/top surface is a flat surface at 1000m and the second/lower surface is a flat surface at 900m then the volume-surface is a surface from 0 to -100.

>> Tin volume Surface is just a color scheme in 2D!

The representation of this surface depends (as everything in Civil3D) on it's style. If you look to this surface from a perspective view and you have set the style to show the triangles in model-view then you should see it 3-dimensional.

You might see it only 2D if you show just analyses data and that like 2D-solids as example.

they can be used in conjunction with the volumes dashboard to spilt an earthworks job into several phases to analyse the cut and fill in each phase as well as for creating sub surface geology surfaces

aside from the graphical representations available , I think you answered your own question
