Spline CVs have more modification options, and they also give you greater control over the spline curvature. We will modify the spline we made in the previous example in the following steps:
- Select the spline so that the fit points become visible.
- Hover your cursor over the knot, and you will see a menu with options, as shown in Figure 8.55:

- If you select the Add Vertex option, it will add additional knots in the spline and make it more refined. When you select Add Vertex, you get the option to place the new vertex in your spline.
- You can also select the Refine Vertices option, which again adds a new vertex, but it will do it automatically without requiring you to add a point to add the vertex.
- The Remove Vertex option will remove the selected vertex, and the adjoining vertices will then join to complete the spline.
Just like polylines, you can also modify splines and convert them into different forms. In the following example, we will learn how to modify a spline using the SPLINEEDIT command.
