A quick look at your drawing reveals a few problems.

The exterior linework is shown as being a lightweight polyline with a negative "Z" elevation of -0.2142.  The interior linework is called out as a region with a positive "Z" elevation of 0.1275. 

You have used a solid hatch pattern and it sits at a "Z" elevation of 0.0. 

You have an extra line and a region (vertically positioned) in the lower right hand corner of your wall that doesn't belong there.

I'm assuming since you are using an educational version of AutoCAD that you are a student.  Has your instructor gone over working in a 3D environment?

And you have one MAJOR problem.  You used the default AutoCAD template file (acad.dwt) which is set up to use decimal inches.  You are NOT working in metric units.

Although AutoCAD thinks is terms of units and 1 unit can be equal to anything (an inch, a meter, a lightyear) for the sake of expediency you should be working with a metric template file, such as acadiso.dwt, which in the end will make your life much easier.

A 3D wall with a concrete block material applied.  Visual style: Conceptual.  I did not play around with the material mapping feature very much.  I just sort of eye-balled it just so you could get a rough idea.  It would need more work obviously.

This is about as far as I want to go for the moment.  You really need to work on your basic 3D skills before even attempting something like this.

If this is for a school project then I suggest you consider using the free version of SketchUp as you'll find it easier to apply materials to 3D objects.

Given your lack of response I guess we can assume you have given up on this project.
