Hi guys !,Iam new here, so iam sorry if there was theme like this one. So, as u noticed from topic, iam looking for well - balanced autocad addon for landworks. Maybe you guys will know one :)Thank You in advance  

There is a specific version of AutoCAD for landworks - AutoCAD Civil 3D.

This may be a case where accurate terminology becomes important and probably varies widely from region to region, country to country.
 
If the OP's use of the word landscape means earthwork design including cuts, fills, quantities for that earthwork, and utilities, then I would agree that Autodesk Civil 3D is the most suitable software choice.
 
But if the OP's landscape design requirements are the same as they are for most of the USA, then it means something completely different and would include planting and materials plans and irrigation design.  In this case Civil 3D would be total overkill.  Basic AutoCAD would suffice.
 
In my mind "landworks" and "landscape" define two quite different things.

I suggest looking at the add on called Land F/X if you are going to be studying landscape architecture.http://www.landfx.com/
