1. Copy+Paste doesn't work. Don't know why !

2. Copy+insertion point and paste+insertion point, doesn't exist. But they appear in Help !!. And, also, paste as block command.  Very important when using block created in other cad software !!

3. Wblock works with errors. The file write to disk, needs Recovery in Autocad.

4. Insert block after Wblock doesn't work.

5. Rapid Autocad like commands: Stretch/Move/Rotate/Scale/Mirror - is not ok.  It has something like ?Stretch/Move/Rotate/Rotate/Scale !? Where is the dialog with parameters ?

6. Request: Copy and Rotate commands in right click flying menu.

Enough till now.
