Powerdraw |

Powerdraw is a free drafting program.

It has a macro facility based on Pascal but it has no trigonometric functions and no square root, etc.

So, this file has some notes (and actual complete programs as .cmf) on horizontal, vertical, and

vertical decliner dial programs, and meridian and polar dials, and a calendar (declination) curve

generator for any SH from 23 to 80 degrees. This zip file is complete with trigonometric methods,

and issues found in Powerdraw. The functions sin, cos, tan, and sqrt work for all ranges, the arc

functions (asn, acs, atan) also.

Documentation is marginal for Powerdraw, the notes and the hDial, vDial, pDial, mDial, and vDec

are good sources for "programming by example" should you wish to play with Powerdraw.

The functions good for all negative and positive values, are in:-
