Hex-CAD is Khitchdee's in-house tool for CAD on a hexagonal grid.
The hexagonal grid is a better way to organise 2-space than the cartesian grid.
The angles on a hexagonal grid
It also a better design vehicle for CAD.

We plan to connect the output of this tool to CAM tools
to enable precision fabrication of parts needed in structural design.
Hex-CAD is the cornerstone of Khitchdee's Unit-construction-hub
which is our micro-factory installation for land-vehicle design.

Hex-CAD is a Hex-mapped app.
It has an efficient custom UI that is fully keyboard controlled.
