I couldent get the images to load up, maybe its my internet connection???
If youve got hard edges (like if you just create a cube, the edges of it) then you might want to have a look into the poly bevel command, its under edit polygons (or mesh depending on the version of maya your on)
If you have a look in the help files for bevel than theres lots of help for it to guide you through the settings
