THE HEXAGONAL-GRID AS A CAD TOOL DEVELOPMENT AID

A Hexagonal grid is like an extended virtual protractor (the instrument used to measure angles).
The use of a hexagonal-grid helps choose or specify angles and curves in a mechanical CAD process.
It is easy to make small rotations in 3D on a hex-grid.
In a Cartesian grid based system this is done through numerical (degree) input.
