"central" doesn't mean anything and is being ignored.  (Hence the error
message.)  You can remove it.

The "center" option means to center the object on the origin.  Exactly
what that means depends on the object.  Spheres are always centered. 
Cylinders default to being centered in X and Y - that is, the circle is
centered on the origin - but extend from zero up in positive Z; setting
center=true has them extend from -height/2 up through the origin to
+height/2.  Cubes default to having one corner at the origin and
extending in +X/+Y/+Z; setting center=true centers them on the origin.

Venturi.  It's named after an Italian scientist named Venturi, so it
wouldn't be surprising if it's very similar in many languages.

Have fun.
