Wouldn't you be better off using materials?

You are working in 3D and will, from the sounds of it, most like create a rendering yet you do not recognize the word "material"?  How long have you been using AutoCAD?

If you populate your drawing with blades of 3D grass and rocks/pebbles/stones that are 3D your drawing file size will increase dramatically?  Do you have enough RAM and a good enough video card to handle the task?

As regards stones and grass my answer remains the same.  Use materials (or textures).  You'll have to make use of a "bump map" to give the appearance of height.  BTW...you can attach materials by object or by layer.  Attaching by layer is more efficient.

You can find 3D trees here and at other CAD related websites.  Before downloading any of them look at their initial file size then do the math.  You should be able to estimate how much adding a certain amount of trees will add to your drawing file size. 

What are the specs on your computer?

If you haven't used materials/textures before then you should read up on their use.  I think it is better to assign a material to a layer rather than to an object.  This means that any object put on a layer that has a material assigned to it will be rendered using that material.

If your object is not a mesh, a surface or a solid then you cannot assign a material to it.

Yes, EXTRUDE will give objects a height.  I thought that's what you wanted.  Aren't you doing this in 3D?  If you are doing this in 2D then you need to use hatch patterns.

Explain what you are trying to do and attach a drawing to your next post.  This is taking way too long to accomplish.

Normally you do not hatch a 3D object; you hatch 2D objects.

3D objects will normally have materials/textures applied.  They can be applied 'by object' or 'by layer'.  Materials can even be applied to 'faces'.  We have been over this a couple of times now and you do not seem to be able to grasp the concept.  You must have very limited or no 3D experience.

Extrude your wall then apply the appropriate material (concrete block).
