Creating a Block, layer 0 recommendation

[lordofbikes]

In section Creating a Block see Important notice at section end.
There is a bold recommendation to only and exclusively use layer 0 for blocks.

I think this is not true, it can absolutely make sense to use different layers than 0, e.g. when the block contains decoration or references which are optional for printing.

I recognized this in a forum post, where I added some steps to explain and clarify block functionality.

My understanding at least with Autocad, is that it can be handy in a block intended to be used frequently in architecture, to put everything on the 0 layer. And have items color by layer. Then if the block is an electrical outlet for instance, if inserted into say the layer for 2nd floor electrical, it will take on those lineweights and color and only show up visible when that layer is turned on.

I will have to look at that special setting mentioned in the forum post.

Another reason to put such things on the 0 layer, is that standard layer names may change in your organization and having the block into the active layer whatever that name is, can simplify things.
