and I want to subdivide it like this: http://mysite.reblended.com/kroopson/2.jpg
using just one command so I won’t have manually select verts, subdivide edges, delete some of them and create faces again.
beauty subdivide works along the loger (opposite) sides of a face
something else to try is to extrude half of your object (hold control this time), hide what is now selected, move (manually, though scaling and stuff helps) the verticies on the edge of where you extruded to where you wish them to be (probably in the middle, or so), deselect all, unhide everything, and move it back (holding control again)
subdivide your polys using the normal subdivide command… and you end up with a bunch of triangles, so… select all press ALT + J to join the triangles into quads. blender usually does a good job of knowing which triangles you want to join into a quad. this is the method that has me doing more serious modeling in blender. hope this helped.
Glad I could help. BTW I found out you only have to press J KEY to join the triangles into a quad! Nice model too, things should be a lot more fun now!
