Datum and tolerance blocks in assy drawing

[Geneg]

In my assy drawing all datums and tolerance blocks are visible and need to be not visible.

Is there a way to make them invisible, its somebody huge assy and not easy to find what part and subassy carry those entities.

Thanks,

Blank the layer they are on.

Just turn off 3D annotation display and datums.
