i have no clue how to make a piece of 3/4" mdf in SketchUp angle, and how to determine what degree it needs to be angled at to meet up perfect with the vertical piece of MDF below and the horizontal piece above.
never mind, im doing a wall now, so this box idea got thrown out the window //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
