Editable Poly Tools
Let??™s experiment with some of the other Editable Poly tools. Dive right into the following
exercises.
Extrude
When you extrude a vertex, 3ds Max moves it along a normal??”that is, a line that is perpendicular
to the surface in most cases. The extrusion creates new polygons that form the
sides of the extrusion that also connect the vertex to the object.
We will start by extruding a vertex on a sphere:
1. Create a sphere by going to the Create panel and selecting Sphere. Create the sphere
with about 20 units radius. Convert the sphere to an editable poly by right-clicking
the sphere and choosing Editable Poly under the Convert To heading in the right-click
menu. Go to Vertex mode, or press 1 on your keyboard. The vertices will appear as
blue dots on your model.
2. Select a vertex on your sphere. The vertex will turn red. Go to the Edit Vertices rollout
in the Modify panel, and press the Settings button (next to Extrude) to bring up
the dialog box shown in Figure 4.27. Set an exact extrusion height and base width,
and click Apply to create the extrusion. You can also click and drag to interactively
pull out the vertex. Figure 4.28 shows a single extruded vertex.
