As you can see in point type menu, there are more point types than mentioned here. Most of them are symbols for speleothems, passage fills, passage ends, equipement… We will don't mention them here, because it's only an introductory work. Many of them don't need any option tobe used (i.e, speleothem points). We suggest you to try these points. If, after compilation, they don't show as expected, go to thbook.pdf and read about this point type options. You'll find it on pages 18, 19 and 20.
