I think you might be confused (?) about this. In order to use the HF_Cylinder
macro in "shapes.inc", you need to #include "shapes.inc" in your scene. (That's
covered in the documentation about #include files; and perhaps in the section
about macros too.) The macro *code* is there. Shapes.inc is available in
POV-Ray's insert menu-- at least it is in my own versions of POV-Ray. Then you
add

HF_Cylinder(...)

to your scene, to 'call' the macro, with the parameters you choose, and it makes
the (mesh) cylinder. The "shapes.inc" file has these additional #includes inside
it:

#include "shapes_old.inc"
#include "consts.inc"
#include "transforms.inc"
#include "strings.inc"
#include "math.inc"

Now, note that "math.inc" also includes "functions.inc" within itself; so you
don't have to add that.

I suspect that you initially tried to copy and paste *just* the HF_Cylinder
macro code itself into your scene (taken 'out' of shapes.inc); that would not
work, just by itself.
