Sure, you can start by looking at the tutorials.

Thank you. Now I have already export the model into STL format. I wonder if I want to dig some irregular arranged holes in the model, how can I do?

The SurfaceToolbox module provides some functionality to cleanup and process surface models.
See https://www.slicer.org/wiki/Documentation/Nightly/Modules/SurfaceToolbox

Note that we are currently working on improve the modules, see Surface toolbox revamp and https://www.slicer.org/wiki/Documentation/Labs/Surface_Toolbox_update

The Scissors tool in the Segment Editor could be just what you need for that.

There is a short tutorial for this: https://lassoan.github.io/SlicerSegmentationRecipes/Craniotomy/
