Does anyone know how to rotate object 45 degree ? Thanks in advance.

Just type cheat boolprop allow45degreeangleofrotation true
Exactly like that! i recommend toi to write that cheat on a paper so while playing your game toi can type it.You open cheat box clicking ctrl,shift und c at the same time. Hope I helped!
And btw,to rotate something in 45 degree,click on this : ,
Yes,just this ,
Grab that thing toi want to rotate,and just click ,
Keep clicking on , if toi dont like the pose of the thing. :]
But make sure toi typed the cheat first :)

Type 'boolprop allow45degreeangleofrotation on' without the's and then select the furniture ou whatever else. Use the < and > tools to rotate the item that direction, and it will rotate it diagonal as well. Hope I helped
