Explore the process of creating grading criteria in a 3D modeling software program, focusing specifically on relative elevation. Get a detailed walkthrough of how to navigate the software, adjust parameters and criteria, and input specific targets in order to achieve the desired grading criteria.
Key Insights
- The article provides a detailed walkthrough of creating a third grading criteria in a 3D modeling software, focusing on relative elevation.
- The process includes navigating to the grading criteria sets, selecting the target as relative elevation, and inputting specific numbers to flag any missed steps during the creation of the grading set.
- Two types of relative elevation targets are created - one based on slope and another on distance, to cut out an additional step during the creation of grading objects.

Now that we've created two of our grading criteria, we're going to go ahead and create a third one. We're going to navigate to our grading, Grading Criteria Sets, Dev Grad.
We're going to go ahead and right-click and select New. I'm going to go ahead and go to my Criteria tab. I'm going to go to my Target and I'm going to drop down and select the next one in the list of targets that we have available.
We've done Surface, we've done Elevation, so now we're going to be working with Relative Elevation. So from Relative Elevation, I'm going to go ahead and navigate back to my Information tab to change the name of my criteria set. I'm going to go ahead and type in Relative Elevation, and then I'm going to navigate back to the Criteria tab.
Now that I'm in the Criteria tab, I'm going to start walking through the individual options or parameters inside of our criteria set. We have the Target, Relative Elevation. We have the Relative Elevation.
This Relative Elevation is in relation to a Feature Line inside of the drawing. We are going to either go upwards positive or downwards negative. So I'm going to put in a number that is something that's absurd, that if I were to forget to type in my elevation when I create this grading set, it would be an immediate red flag to me that says, hey, you forgot a step when you were creating this grading group.

So I'm going to go ahead and put in a number like 500, and then I'm going to go down to Projection. Because we're relative to a Feature Line, we're either going to be doing all cut or all fill. We don't get the choice to do cut and fill together.
It's just going to do one or the other based on our relativity to that Feature Line. So from here, we have this Projection option. It's just Slope or Distance.
You can project to a Slope or you can project out to a Distance. In this case, we'll probably create two of them. I'm going to create a slope-based one first, and then I'm going to create a distance-based one.
So I'm going to go ahead and do Relative Elevation – Slope. Then I'm going to go to this criteria. I'm going to go ahead and choose Slope.
I'm going to leave my Slope here down as format of Slope instead of Grade. I'm going to choose 2:1, and I'm going to leave it as Use Average Slope. I'm going to go ahead and click Apply.
I'm going to go ahead and click OK. And we're going to see this Relative Elevation – Slope show up here. I'm going to go ahead and go back into Dev Grad, right-click, select New.
I'm going to go in here and I'm going to type Relative Elevation – Distance. I'm going to navigate back to the Criteria tab. I'm going to go ahead and select my Relative Elevation.
I'm going to go ahead and go to Projection, drop-down to Distance. I'm going to put in a Relative Elevation of 500. Then I'm going to go to Distance.
I'm going to do another absurd number, 500. Then I am going to go ahead and click Apply and click OK. Now we have two Relative Elevation targets.
We have our Distance and our Slope. When we're creating our grading objects, we could have just gone with one Relative Elevation and changed whether we were doing Slope or Distance, but this will just cut out one step. So I'm going to go ahead and save my drawing.
And then I'll meet you in the next video.
