After using sketch up for a while I realized It does not offer the freedom I needed,such that to be able to properly view the inside of a building you have to cut out one wall. I found another program though, Sweet Home 3d which has the capability of staging virtual visit as well as drawing on predrawn picture layouts.
Take a look at Sweetome3D, it's a floor-planning application which is pretty easy to use, and has the benefit of being able to make 3D plans as well as 2D.
It's Free and Open Source, available under the GPL. It has versions for Linux, Windows, and Mac.
After some thought, I ended up creating a full complex pattern using an Excel spreadsheet.
I feel tremendously badass for having accomplished a task I thought I'd have depend on some CAD software and personnel who can work with it.
For anybody else that ever comes across this need and is looking for a solution, here is the spreadsheet: http://files....

Inkscape is a good open source, freeware Illustrator equivalent, runs on Mac, Windows and Linux, and can work with placed raster images, or directly import most vector art formats, from EPS & PDF through DXFs, so you should be able to bring in actual CAD drawings of you have them as a starting point.
I would recommend Graphisoft Archicad. It has a free 30-day trial and for students (ie with enrollment at a highschool->post secondary level with any accredited institution anywhere in the world) it has a renewable one year free educational license. Otherwise it is quite expensive. It is the gold-standard of building design/rendering (though there are ...
There are numerous 3-D modelling packages out there with prices ranging from free to huge sums of money unless you are prepared to spend the ridiculous amounts of money I would strongly recommend downloading and learning blender.
While it is perhaps a little generic for your use it has the following features that you may well benefit from:
Free & cross-...
DC planning software is pretty common so by all means shop around. The product I've seen most recently is Emerson Power planner.

IIRC it requires sensors to be placed throughout the datacenter so you can only use certain features if you own the datacenter, but it's pretty robust. ...
In Sketchup you can access the inside of a building in a few ways:
mark a wall as hidden geometry and view only unhidden geometry, it
allows "click through"
make section planes (a bit advanced functionality but doable)
use the 'mark spot' in - and/or 'step through' a building functionality
zoom in onto a wall, and you'll go "through" it, but I would not

Its an Augmented Reality app that you can use with a tablet to visualise a 3d building over a blueprint. The coolest part is that they are also looking at implementing Oculus Rift and Leap Motion support so you can actually walk through a building and interact with stuff inside it like doors and windows.
