42// Define a C preprocessor constant for a Scale factor to apply to
43// various dimensionless tests in the geometry routines which test
44// if a point is on a surface. This number is an effective thickness
45// of a surface divided by a relevant dimension, such as the radius of
46// a cylinder. The default value is 0.0001.

49// Define a C preprocessor constant for the maximum number of turns
50// allowed for a Helix, which is used in some of the geometry routines
51// to limit the size of for or while loops. The default value is 50.
