autocad drawing database (dwg) can contain various types of anonymous (unnamed) blocks. the pseudo-names of anonymous blocks always start with an asterisk "*". you normally cannot use autocad block editing commands with anonymous blocks.
examples of anonymous blocks:
*u### - general anonymous blocks
*e### - anonymous blocks from non-uniformly scaled blocks - when exploded (e.g. solids, regions)
*d### - anonymous dimensions (dim blocks)
*x### - anonymous hatches (hatch blocks)
*a### - anonymous groups
*t### - anonymous blocks in tables
autocad add-on applications may create also other types of anonymous blocks.
