Can't separate a composite solid

[Jack Cheong]

Use separate for a solid ( solid merge by union command), but return as:
The selected solid does not have multiple lumps.
What it's mean?
Someone can help me?

To use Separate, you need a solid which is logically one item but appears, visually, to be two items.
Example - copy an existing solid so that the copy does not overlap the the original and Union the two together. They are now one logical solid so Copy, Move, Erase, etc will act on "both".
Two make a single lump into two, you will need to Slice or make copies and Subtract bits from them.
