In t2.geo, "newpt[]" is not a command: it's just an array of numbers. I
think you are confusing this with "newp" (the command that returns the
next available point number).

This is wrong: you create a new surface ("news" is a command that gives
you the next available surface number) from a line loop that is actually
the rotated surface.
