Grade to Target isn’t an option when creating grading, but we can get the same result by manually drawing the feature lines for the grade to target affect. The first thing we need to do is draw, or extract, a feature line at the location where we want the target to be.
Next we need to draw two feature lines from the feature to the Target Feature Line.
Next we need to create infill in the area of the enclosed feature lines.
So that’s one way to Grade to a Target, it also has the extra benefit of not having to grade perpendicular from the feature, since we can easily move the feature line to what ever angle we want.
