Hexagonal modellers have to live in a world dominated by a rectangular mindset  and it can be necessary to use rectangular modelling tools. Fortunately, there is a simple isomorphism between the hexagonal grid and the rectangular one. The following Java applet is intended to demonstrate this mapping, by providing a visual representation that morphs from a hexagonal grid to a rectangular one, and back again.
Drag the slider on the right to morph between hexagonal and rectangular styles. The applet should be fairly selfexplanatory  after examining it you should be able to generate hexagonal models using rectangualr tools. Sometimes an "interlaced" mode is used  with alternating rows being moved in opposite directions. Note that a similar mapping is available for those working with triangular grids.
