- [Instructor] Once we have our alignment created, if we need to modify in any way we can treat it basically like a pi line. If I select the alignment, you'll see that we have all of our points of intersection labeled with that triangle. If I want to move it, I can simply select that and shift it. The nice thing about alignments and the advantage that they have over using polylines is that they're going to remain geometrically constrained. This curve will be tangent to all incoming and outgoing tangents. If we want to extend out a tangent, we can choose that PI using any number of snaps and move that anywhere in our model and all of our labels update accordingly. Now if we need to do something a little bit more accurate, let's say this curve radius needs to be adjusted to 1200. The best way to do that is to go here, under the alignment grid view. Here, we have a list of all of our PIs and curves. If I want to change this radius, I can simply choose that and overwrite it, let's do…
