Question
HOW DO I CONSTRUCT AEC WALLS OR HOW DO I CHANGE THEM IS THERE A MENU?

Answer
Mark:  An AEC_WALL is an entity created by either Autodesk Architectural Desktop or by Autodesk AutoCAD Architecture.  These programs are more expensive AutoCAD "vertical" programs.  If you are using Vanilla AutoCAD, you will only be able to move or erase them, if you have the correct Object enabler installed, but not be able to shorten them, break them, clean them up, trim them, offset them, etc.  That requires Autodesk AutoCAD Architecture.  It also will require an extensive learning curve to switch from one drawing method to the other.  So, to answer your question, In plain vanilla AutoCAD, there is no menu, nor no function to deal with AEC_WALLs other than to show them or not (PROXYSHOW), or to notify you of their existence (PROXYNOTICE).  If the object enabler is present, which in your case your message suggest that it is (because you can see them, then you may be able to EXPLODE them, as I can with AEC_CONTOURS from Land Desktop users.
