This Smath document exemplifies the "SVG" [Scalable Vector Graphic].
The algorithm constructs in the normal range of the parmaeter 't'
in the range t:= 0..1. Example 3 "Minaret" is extrapolated over the
last point. We use this extrapolated example to compute the arc length.
In short: graphic packages [AutoCad ...] operate on the same principle.
Except that are gigantic in capabilities with extra functionalities.
Essentially, "Graphic Packages" are data base systems.

Here, Smath does same than Mathcad 8 Pro. Unlike Mathcad that is scalar
wrt 't', Smath is discrete from the very first coding. All in all, both
do SVG, though Smath plots are much better tutoring !

Enjoy for your Engineering projects. Few more basic processing units
can be created in different sizes, rendered clean w/o transiting via
extra tools.
