TurboCAD Professional and later supports parametric scripting which is simpler than their VBS support,
see the h-dial script and notes below... this has many benefits and is very easy to program. The VBS
support needs addons, the parametric script does not, you just do it.
TurboCAD macros are similar to
the DeltaCAD macros, but more finnicky and need TurboCAD Professional which I used to use.

A solar lighting mesh
Using the solar lighting mesh, notes
The file:-             hDialParametricBuiltPHX.tcw

was loaded, see right, then the dial plate was selected, then
VIEW and then SELECTION INFO, then in  the right hand
panel, PARAMETERS was expanded showing the latitude,
longitude, and legal meridian. Changing those parameters
causes the parametric part (the horizontal sundial) to redraw
itself.













VIEW, PARAMETRIC PART SCRIPT EDITOR PALATE brings
up an editor panel
(see these notes), and the script can be
seen and changed if desired. And the script can be run from
that panel, and the resulting parametric part (the horizontal
dial) will then appear. And that result can be saved. And
modify itself much later if opened, selected, and VIEW,
SELECTION INFO used as in the example above.
