+66In CAD features have ID's (handles) which can be exposed.
Example autocad_entity_handle (encoded: utf-16): 2BB
When the option Explode Blocks into Entities is enabled the relation to the original block is lost.
An autocad_block_handle attribute would solve a lot of headaches to restore this relation.
I understand this might be tricky with blocks into blocks but the top block handle should do the job.

Explode Blocks Into Entities
When selected, this parameter explodes blocks and return the entities that form the components of the block as separate features.
When the reader resolves blocks, it outputs a feature for each of the AutoCAD entities that are part of the block definition. The original insert is not output. This results in the full graphical representation of the block transferred through FME, but the exact insertion point of the block is lost.
Each block member feature is given the attribute autocad_block_number which is set to the same value for each block so that the features comprising each block may be combined in subsequent processing. Arbitrary deep block nesting is permitted, however, the autocad_block_number attribute is only updated for each block at the outermost level. By default, all block members will be on the same layer as that of the original block.
