How do you use grading groups in Civil 3d?

To Create a Grading Group

1. In Toolspace, on the Prospector tab, expand Sites, then expand the site to which you want to add the new grading group.
2. Right-click Grading Groups Create Grading Group.
3. In the Create Grading Group dialog box, enter a name and an optional description for the grading group.

How do you create a grading surface in Civil 3d?

To Create a Detached Surface From a Grading Group

1. Click Home tab Create Ground Data panel Surfaces drop-down Create Surface From Grading Find.
2. In the Select Grading Group dialog box, specify the site and the grading group.
3. Click OK. The detached surface is created.

What is grading infill in Civil 3d?

“An infill grading has no criteria applied to it. Any area bounded by feature lines or lot lines that is not already a grading can be converted to an infill grading.” So given an area enclosed by a feature line, an infill grading can be created. Using the same features line, an feature line grading can also be created.

How do you change the point elevation in Civil 3D?

To Raise or Lower the Elevations of an Entire Point Group:

In Civil 3D → Toolspace → Prospector Tab → Expand Point Groups by clicking on the plus sign (+). Right click on the point group you would like to raise or lower. Click Edit Points.

How do you change the surface elevation in Civil 3D?

To Change the Elevation of a Surface

1. In Toolspace, on the Prospector tab, expand the surface Definition collection, right-click , and click Raise/Lower Surface. Note: TIN or grid volume surfaces do not support editing operations.
2. Enter a positive value to raise the surface or a negative value to lower the surface.

Can you extend a feature line?

The extend tool will not cause the elevation to drop to match the target elevation. The slope will be maintained as it extends to the new location. Thus if a featureline has a plus 1% slope and you extend it to an object 100′ away, the new elevation will be 1′ higher.

What occurs if two feature lines occupy the same site and intersect?

Feature lines in the same site can only have one elevation at a crossing point. If two feature lines approach within a tolerance distance of 0.0001, the points collapse to a single point.

How do you extend a line in Civil 3d?

To Extend Line Lengths

1. Click Home tab Draw panel Line drop-down Create Line By Extension Find.
2. Select the line to extend.
3. To define the length of the line, do one of the following: Select two locations to specify the length that you want to add to the line. Enter a positive distance to extend the line.

What is grading in civil engineering?

Different grade of concrete have different compressive strength. Each grade of concrete represents some mix ratio. In general there are two types of concrete mixes such as nominal mix and design mix. The nominal mixes are those whose mix ratio is defined which includes grades of concrete up to M25.
