Wingeom is for high-precision geometric constructions in both two and three dimensions. Drawings can be highlighted and animated in a variety of ways, as these sample files show (12 Jul 10).


The on-line help pages are kept current (1 Jan 12).


There is also some supplementary material (tutorials and labs) available (22 Jan 11).

If the program behaves strangely, there is a page of FAQ, which may help. If not, you can e-mail me at the address found in the program’s Help|About dialog box.

One way to insert a Wingeom diagram into a webpage is to create an SVG file.

For those who have had trouble finding a font that enables Greek letters and other special symbols, try the MS LineDraw font.

1 Jan: Thanks to a report from a veteran user, I was able to correct the 3D inscribed-sphere function, which was miscalculating badly. It seems to be ok now. Happy New Year!
