Leonid Nemirovsky also discovered a method to paste objects as a block.
"I was using Ctrl+C and Ctrl+V to copy and paste AutoCAD objects. But when I was pasting, I accidentally held down not Ctrl+V but Ctrl+Shift+V! To my amusement, the command pasted the selected objects as it usually does, but it kept everything as a block because I held down the extra key."
Notes from Cadalyst Tip Patrol: There are several ways to copy objects in AutoCAD. There is the Copy command, for starters, but it doesn't have the ability to copy from one file to another. If you use Ctrl+Shift+V often, you might want to use the Rename command to change the names of those blocks to something you will recognize later.
