Level editing

I''ve visited http://www.flipcode.com/tutorials/tut_levedit.shtml. I''m looking for an easy to use level editor that simply generates vertex information. Luke on the above site includes a download program for converting .map files that generates vertex and face info. I can''t get this to work. I''m sure there''s a good number of you out there that when you finally discovered how to write a a (BSP) software renderer (yipee - after 3 months of effort!) you got fed up with graph paper and the like to manually build a test world. Any ideas re: shareware / freeware programs that simply generate vertex info? Or, perhaps a file format that a level editor generates that''s documented that I can post process to generate vertex info? Thanks guys (and girls?) Martin
