Hex-draw is a PC app for drafting on a hex-grid.
It is the first incarnation of Hex-CAD.
Screenshot of a bike sketched using a hex-draw prototype:
Hex-draw's GUI is based on Hex-map, not WIMP.
All user input comes from the keyboard.
It is very efficient compared to a WIMP UI.
We plan to share a public prototype by the end of 2021
