I’m learning about blocks in AC2006.  I created a layer to hold the block (Block), then selected a component from a different layer (Drawing).  After the block was created I found that the Drawing layer was now empty.  Is this normal?  So if I had used drawings from several layers to create the block, those parts used in the block would vanish from their respective layers?  Is there any way to avoid this?

I’m thinking of a situation where I may want to have several blocks that use some of the same parts, but the parts need to be modified before each block gets created.  To lose the original drawing layers makes this difficult.

Any suggestions?

Thank You,
Roger
