AutoCAD 2012 introduced a few stellar productivity enhancements - some are well known while others definitely remained under the radar. Adding in an Array option to the COPY command fell under the latter category - but is definitely a powerful tool to be aware of!
How many times have you gone into the COPY command and wanted to copy objects a specific distance apart...over and over again? The ARRAY command would do the trick - it's just a bit overkill sometimes. Enter the cool stealth Array option in the COPY command. Check out my Cadalyst video for more info on how this feature works!
Enjoy! Now you are in the know!
