Improve your understanding of grading criteria sets with this article. Learn how to create a new grading criteria set, select the right parameters, and adjust them for optimal results.
Key Insights
- The article demonstrates how to create a grading criteria set with different parameters such as distance, slope, and relative elevation. For example, you can input an absurd number that will signal if a step has been missed.
- The projection methods discussed include slope and relative elevation. These options can be selected under the criteria tab and can be adjusted based on personal preference or project requirements.
- The grading criteria set created in the tutorial has two distances, distance-relative elevation, distance-slope, elevation, relative elevation, distance-relative elevation-slope, and surface. This comprehensive grading criteria set offers a thorough understanding of how to manipulate various parameters.

We're going to go ahead and work with the last Grading Criteria that we have. We're going to go to our grading, Grading Criteria Sets, DevGrad.
We're going to go ahead and select DevGrad and right-click and select New. We're going to go ahead and go to our Criteria tab, go to our Targeting Method, we're going to drop down, and we're going to select Distance because we've already done Surface, Elevation, and Relative Elevation. So I'm going to select Distance, I'm going to go to my Information tab, and I'm going to go ahead and type the name "Distance."
I'm going to go to my Criteria tab again, and I'm going to walk through the different parameters. So what we have here is a Distance, so I'm going to go ahead and again select some absurd number that will give me an instantaneous red flag that I've missed a step. If I forget to type in a Distance, I'm going to go ahead and go with another one of 500.
I'm going to go ahead and choose a Projection method of Slope. I'm going to go ahead and do two again like we did for Relative Elevation. I'm going to go with Slope and then I'm going to go with Relative Elevation.
So I'm going to go ahead and go to Distance – Slope. I'm going to go to Slope here. I'm not going to change the Grade because I like working with Slope ratios.

So I'm going to go ahead and leave this as 2:1. I'm going to leave this as Use Average Slope. I'm going to go ahead and click Apply and click OK.
Then I'm going to go ahead and go back to DevGrad, right-click, select New. I'm going to go back to Criteria. I'm going to go to Distance.
This is a Distance that is coming off of a Feature Line. So our Distance is going to be going out a certain distance and then coming down based on either Slope or Relative Elevation. We can go positive Slope or negative Slope, or we can have a positive Relative Elevation or a negative Relative Elevation.
So I'm going to go ahead and go back to my Information tab, type in Distance – Relative Elevation. So I'm going to go here, Distance – Relative Elevation. I'm going to go ahead and go back to my Criteria tab.
I'm going to go to my Relative Elevation. I'm going to type in again another absurd number like 500, and then I'm going to leave it as Use Average Slope. I'm going to click Apply and click OK.
And so now we have a Grading Criteria Set that has two Distances: Distance – Relative Elevation and Distance – Slope. We have Elevation, we have Relative Elevation, Distance – Relative Elevation – Slope, and then we have Surface. From here, I'm going to save my drawing and then I'll meet you in the next video.
