1. Copy with Base Point command
Right click > Clipboard > Copy with Base Point.
2. Select Base Point.
3. Select objects to make into a block
4. Paste as Block command
Right Click > Clipboard > Paste as Block
Here is the tricky part; if the Paste as Block command in the right click menu is shaded back, then you will need to select an object (any object) in your drawing before using the Paste as Block command.
The objects are now in a block which makes it easy for copying and editing.
Enjoy!
