Bruno, if you just started with Sketchup, do you know that you can enter the dimensions simply after setting the startpoint? For example to draw a rectanlge simply click on the starting point an then enter the dimension, separated with a ; Be sure to set Sketchup to metric dimensions (or whatever you prefer) 
Yeps, but I've used for that first draft the 'outside' values of the room. I'll create a new project with the 'real internal' values, which should me more like 7,60m x 9,75m, when removed the size of the walls, and other insulation parts (which are estimated atm).
In addition, I know that you've been collecting some spare parts (LD players for example) what about the actual projectors? Were you planning on using those analog beasts, or were you go upgrade to something more modern (smaller, sharper and uses a lot less power) ??
Yes, I have some spare parts, but I also have the idea to try more 'modern' projectors.
Bruno, try placing the teather in the middle of the room and see if you can place some cabinets close to the walls...
It's a cool idea. I'll figure out if it's an 'accurate' location for the GT6 (Galaxian Theater model name, but you all know this
). The idea is to also have as much space as possible for other games...
2012 WILL BE the Galaxian Theater year! 
Great news, when are tickets avaialable? 
Hehe, there'll be a run of 50 'collector' tickets
! Can't wait too
OK, back the the floor...
...let's say it's 95% done
I'll put the last pieces when the door (already ordered) will be there, or when I'll have a better way to close the hole of the *missing* door.
