- If a block is created in a drawing, it appears that the block "definition" is on the layer it was created on. If the created block has entities on multiple layers, the definition retains that information
- If you hide that layer, all the references to that block are hidden. If the created block has entities on multiple layers and you hide one of them, part of the block disappears from each reference.
- If you explode one of the references, the resulting items (lines, etc.) are placed on the original layer, not the same layer as the reference
- Create all my blocks on layer 0 (which I normally don't use)
- Explicitly set line types/colors/weights for all the block elements
- Try to avoid exploding blocks
