Blocks will not turn off

When selecting the layer that the blocks reside in, and turning off the layer, the blocks remain visible. All other items on that layer do turn off. How do I fix this? Thanks.

The entities in the block are on a different layer. However, if that layer needs to be on for other objects, turning them off may not be an option and you will have to find another way to get what you want.

Entities inside a block don't always behave the way you might expect. Blocks are all about inheritance. When you insert a block, you're really inserting an instance of the block. It's a reference to the definition of the block, which is off in a table somewhere. The block reference has its own layer assignment.

When you assign an item to layer 0 inside a block, it's like assigning the color ByLayer. In a block instance, that entity takes on, or inherits, the layer of the instance. For any other layer, an entity keeps the layer it had inside the block definition, that is, it's not inherited.

Sorry if you knew that already, but as RobDraw guessed, that's probably what's happening. If you can't fix the problem by redefining the block, please give us more information or post the block.

as RobDraw guessed.

It wasn't a guess.

That's how it's always worked. Just freeze the block's layer.

If it was my misbehaving block, I would double click on the block to open it and put all its components onto the one layer that I want it on.
