Much can be done in blender, its just not optimal. Much has been discussed and attempted to make it more capable. Here are some handy resources:
http://wiki.blender.org/index.php/Scripts/Manual/CAD/Caliper - macuono’s measuring script
http://www.rab3d.com/ - rab3d’s excellent resources (see esp. the tutorial)
http://blender-archi.tuxfamily.org/Main_Page - Blender for Architecture
http://wiki.blender.org/index.php/Scripts/Catalog#CAD_Tools - the wiki link list
…and lots of others
As to export to DXF, there’s an exporter already in there, I think. Not sure how well it does, tho.
