"Duplicate entries have been ignored" is they a way to control ignored or overwritten

When you drag a layer from design center into a session of Auto CAD where that layer already exists, the text at the command prompt proclaims that "duplicate entries have been ignored." Is there a system variable that control whether duplicates are ignored or overwritten?

Not that I know of.
Using the insert command prompts for redefining the properties; not sure if that can be done via a palette.

I don't believe so; I know this has been submitted to the wish list in the past, but I can't recall if it ranked high enough or not.

Just wondering, are you trying to either create or update the layers in the target drawing depending on if they exist or not?

We have several situations like this and we use lisp code to do this. The lisp simply creates the layer(s) if they don't exist, then sets the properties of those layers (regardless if they were existing or not).
