# How do you do cut fill in Autocad Civil 3D?

## How do you do cut fill in Autocad 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 is cut and fill factor in Civil 3d?

Quantity Types

• Cut. Used to calculate the material to remove.
• Fill. Used to calculate the material to add.
• Cut and Refill. Used to calculate the material to remove and add based on a refill factor that is different from the cut factor.
• Earthworks. Used to calculate the total cut and fill volumes.
• Structures.

#### What is cut and fill volume?

The cut portion is the volume between the upper and lower surface when the upper surface is above the lower surface. The fill portion is the volume between the upper and lower surfaces when the upper surface is below the lower surface.

What is cut factor and fill factor?

The cut factor is used to adjust the volume of excavated material to account for the amount you expect the material to swell when it is excavated. The fill factor is used to account for the additional volume of material that would be required due to the compaction of the soil when it is placed.

Which is more expensive cut or fill?

To avoid needing to fill in or remove the excess mass, the cut and fill process is planned in a way to keep both the cut and fill masses approximately equal. Overall, a cut and fill operation is expensive. As more land is moved and more equipment and labor are required, the cost of excavation increases.

## How do I know if I should fill or cut?

What Is Cut and Fill?

1. Cut: Earth that is removed from an area is considered “cut” or excavated earth.
2. Fill: Earth that is brought into an area is considered “fill” or embankment earth.

### What is cut and fill factor?

#### What is cut fill ratio?

The cut/fill ratio is determined by the type of material being moved and what percentage of it will “settle” or “shrink” once compacted. Example: Setting the Cut/fill ratio at 1.2 means that you are moving at the rate of 1.2 cubic yards of cut to get 1.0 cubic yards of compact fill.

How do you calculate fill material?

Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 27 (the amount of cubic feet in a yard). The final figure will be the estimated amount of cubic yards required.

What is cut and fill factor in Civil 3D?

## What is meant by cut and fill?

In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments, so minimizing the amount of construction labor.
