# Making Caves With The Extruder

Set the Path to follow the general shape of the cave. Eg

- [0] (0,0,0)
- [1] (4,0,0)
- [2] (8,0,1)
- [3] (12,0,0)

Set ShapeSource to the preset circle, "pCircle" and build.

To change the size, experiment with ShapeFactor and PathFactor.

Set the randomizer to something like:

- X = 0.5
- Y = 0.5
- Z = 0.1 or 0
