I was "forced" to used this 3D design software, AutoCAD, to draw out a room...
looks simple but it surely is damn difficult for starters like me...imagine, you got to align every line in 3-D space...shag! haha..but lucky i managed to figure out easier ways to do within few days...nice prog...used by pro...but the function nt reli helpful coz u won't understand its instruction...
