* It is possible to set the grid quake like in view properties
* I suggest to make a hexagon on 8x8 grid then split and then copy and paste, splitting process is way shorter then. The Problem: editing the mesh by pulling single vertices wont work because they are not connected.
However it still works very good with the PROPORTINAL editing tool (press O) Of course don't forget to snap everything to the 8x8 grid (shift+s)
*I recommend to scale the extruded vertices along Z by 0 , -> then they form a plane. (looks better)
*everything works with blender 2.5 too but the q3.map script is not included yet so you have to open it with 2.49
