Yet, when I run the "refine by splitting" command something strange happens. It appears that some of the newly added nodes aren't placed in the extrusion path.  This leads me to believe that there is some problem with the way I've defined the surface, but I couldn't find anything suspicious with it.

Hi Rui - Indeed, you hit a limitation of our "refine by splitting" algorithm--it will correctly put surface points back on the CAD, but not volume points.

To refine your mesh you should introduce a parameter in your .geo file instead to change the number of layers, etc.
