Exporting a Block with hidden layers not working

When any layer within a block is hidden, and then exported, it is expected that only what is visible will be exported. This is the case for DWG, but for FBX the exported FBX file contains all layers and objects within a block.

Is this a bug or an expected exception for FBX

Hi Michael - as far as I can see, exporting blocks to DWG exports objects on hidden layers.
