Brad,
The only problem I still see with this is the fact that this ONE
mechanical layer is in fact still one layer and not easily
if at all able to be separated out for the bottom assembly view.
If there is a way I would love to hear it, I have in fact used
a mechanical layer in my library for an assembly layer in hopes of future
enhancments from Protel to actually use this layer properly.
For now I use as you stated, but there really needs to be an association
with two layers for this to work right. If there was a way to change
all bottom parts using this machanical layer to another layer that would
work but again not clean, this should all happen as soon as you push
the part.
