How do you compare volume?

Anytime you go to a store and compare prices based on size, you are comparing based on volume. You can divide the price by the volume to determine the price per unit volume.

How do you calculate volume difference?

Volume Difference = Cut After – Cut Before. Volume Difference has positive value: material was added. Fill volumes have negative value. Fill volumes have negative value.

How do you make a cut fill surface in Civil 3D?

Solution:

1. In command line type “COMPUTEMATERIALS”.
2. Select the alignment and sample line group to sample, then click “OK”.
3. Change “Quantity takeoff criteria” to “Cut and Fill” or other desired criteria.
4. Map the sampled surfaces to the correct object names, then click “OK”.

What type of surface is used to compare two surfaces for calculating cut and fill?

But, there’s a second type of surface, a Volume Surface. You guessed it, the main purpose of this type of surface is for estimating volumes or earthworks quantities. Volumes are the amount of material, Cut and Fill, that you will need to transform a surface from an initial to a final state.

What is a TIN volume surface Civil 3D?

A TIN volume surface is a composite of points in a base surface and comparison surface. A TIN volume surface provides an exact difference between the base and comparison surfaces.

What is tin surface in Civil 3D?

A TIN surface comprises the triangles that form a triangulated irregular network. TIN lines form the triangles that make up the surface triangulation. To create TIN lines, AutoCAD Civil 3D connects the surface points that are closest together.

How do I show cut and fill on a site plan?

This method involves drawing horizontal and vertical lines over your site plan to divide it into grid cells of equal size. You then include the existing elevation and proposed elevation for each corner of the grid cells, and work out the difference between the two, as this will be cut or fill depth for that spot.

How do you read a cut and fill report?

The cut or fill depth for each cell is found by subtracting the average existing level of the cell from the average proposed level. If the resultant depth is positive then this is a fill cell, while a negative value indicates a cut cell.
