What is the difference between grade and slope in Civil 3d?

In Land Desktop a Grade is always expressed as a percentage and a value of 5 would imply a 5% grade which gives 5 units of vertical for every 100 units horizontal. A Slope is the inverse of the Grade – but not expressed as a percentage. Thus a Slope of 5 would imply 1 unit vertical for5 units horizontal.

How do you create a grading side slope from a feature line in Civil 3d?

When prompted to select a feature, click the blue feature line that is offset from the building pad. When prompted to select the grading side, click outside the offset feature line. Press Enter to apply the grading to the entire length of the feature line. Press Enter to accept the default Slope Cut Format.

How do you calculate slope in geography?

To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.

How do you find the surface slope?

Slope is measured by calculating the tangent of the surface. The tangent is calculated by dividing the vertical change in elevation by the horizontal distance.

What is the slope symbol?

Slope is often denoted by the letter m ; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O’Brien (1844) who wrote the equation of a straight line as “y = mx + b” and it can also be found in Todhunter (1888) who wrote it as “y = mx + c”.

What is the difference between slope and grade?

Grade is the same as slope but uses a percentage to indicate the measurement. In our example, a 0.5 slope means that it has a grade of 50 percent.

How do you grade a surface feature line?

Feature line grading involves creating a set of feature lines to define the graded region as surface breaklines, and then adjusting the elevation of key points to control the shape of the surface. This technique is ideal for wide, fairly flat areas such as parking lots or building pads.

How do you grade a swale in Civil 3d?

Give your Site a logical name like Swale Grading. (by the way a “swale” is a term for a simple drainage ditch). Assign a style to your feature line and specify a layer like “C3D-FEAT-“your Site Name”. Click OK (This Feature line will represent your flow line of your swale/ditch).
