Updates to 'Fortran Friends' Polyhedra programs

The upgrading method changed on 1 March 2001

The new method applies only to versions of:

• !PolyDraw version 3.03 onwards

• !PolySymm version 4.00 onwards
• !Stellate version 1.01 onwards

Updating Instructions

1. First you must have a valid registered version
2. download and unzip the demo version of the program you want to upgrade:
   PolyDraw (size 397K) PolyNet (size 130K) or Stellate (size 603K) PolySymm (size 456K)
3. Download, unzip and run the upgrade program (143K latest version 20 Feb 2006)
   [Users with floppy only systems should do this in RAM disc]
4. when asked to do so:
   • drag in the filer icon of your registered version [may be on floppy]
   • drag in the filer icon of the demo version you just downloaded [may be on floppy]
   • the demo version will be converted to a full registered version
   • please send us an email telling us of your success (or otherwise), giving the program name, your name, registration number and new version number so that we may keep our records straight.
     Thank you.
