Finding myself house bound for a few days, and remembering someone mentioned
Powerdraw a few months ago, I decided to look into it.
I have macros for dials in TurboCAD, DeltaCAD, NanoCAD, FreeCAD, ProgeCAD, and
Blender (which is a modeling system rather than a CAD system). But I had
avoided Powerdraw.
I downloaded Powerdraw from:- http://www.powerdraw.software.informer.com/
and discovered that user comments that it lacked documentation were true. In
fact not only was there little documentation, it turned out that the macro
language was a subset of Pascal, and lacked basic trigonometric essentials such
as SIN, COS, TAN, ATAN, and so on.
Undaunted, and trying to burn off the Thanksgiving turkey and loads of sherry
trifle, I wrote a SIN, COS, TAN, and ATAN code segment, and produced two macros
for Powerdraw. One for horizontal dials, one for vertical true south dials,
complete with hour lines, their hour, their hour line angle, and the gnomon
also.
I have no intentions on doing any more with it, but they are on my web site for
anyone interested in using Powerdraw.
