- [Instructor] In our last exercise, we created a very simple alignment. It had no curves, it went in a U shape, we added simply three segments or tangents to the alignment. Let's look, we're going to edit the alignment by adding curves, and in the process we're going to learn a little bit about some of the constraints with the alignment geometry. So we're going to open up our exercise file 0603. We see the alignment that we created in our last exercise and so we're going to select that alignment to get it's contextual ribbon, and we want to get that toolbar back that we had when we first were creating the alignment. So I'm going to choose geometry editor, and this allows us to add additional geometry, add additional PIs, which would break the existing geometry and create two segments. We can delete PIs, we can add simple lines, curves, and segments instead of using the multiple tool here. But notice as we look at these different geometry elements that are part of an alignment, that…
