ok, i'm trying again with sketch up
now, i want to move an object to an exact location, x,y,z. not just moving it around with the mouse.
how do you do? i read the guide and it says something like entering [x',y',z'] on the value box, but i have a problem with this: for making the brakets  i have to press the alt button, that automatically interrupts the command so i'm unable to move.
Also, how do you see the exact coordinates an object is ?
