I cannot seem to get any of the blocks to transpher into the file. I tried the drag and drop. The test chair works but others do not. I then tried to save them and I don't know if I am saving them in the wrong file, but I cannot get the blocks to open. HELP.

What blocks are you talking about?What AutoDesk product are you using?If you downloaded the blocks from a website where did you store them on your computer?  Are they just sitting on the desktop or did you put them in a folder?Are you working in metric or imperial units?The blocks are just dwg files right?  Have you tried opening one?
