editable poly tools ?– 137
This tool can be very convenient. If you have done something to a polygon but don??™t
like it, you can delete that poly and use the Cap tool to create a new one. Keep in mind,
however, that cap will use a flat polygon to fill the hole, so a complex surface hole will
not be patched with the same surface contours as the original.
Extrude Along Spline
The Extrude Along Spline function works just as it sounds. It will extrude a polygon subobject
along a spline path, which is a curve drawn in 3ds Max. Splines will be introduced
later in this chapter and covered more extensively in the following chapters.
To see the Extrude Along Spline function in action, open the Path Extrude.max file
found in the Chapter 4 directory in its Scenes folder. This file has a sphere that has already
been converted to an editable poly and a spline that will act as the path of extrusion. To
continue, follow these steps:
1. Select the sphere and go into Poly mode (use shortcut 4, or select the Poly icon in the
Modify panel??™s Selection rollout). Select a polygon; it doesn??™t matter which one.
2. Click the Settings button next to Extrude Polygons
Along Spline to open the Settings window for the
tool, as shown here.
