layer filters in lisp?

Is it possible to set a specific layer filter programmatically (i.e. to include in acaddoc.lsp and apply on file open)?

Thanks

AFAIK, you can create a layer filter through LISP, or query the properties of an existing filter (filters are stored as XRecords in the Extension Dictionary of the Layer Collection), but without going through the Layer Manager, you cannot set the filter current through LISP.

I was afraid of that.

Thanks

You're welcome, sorry to be the bearer of bad news

Hi, it IS possible:

Have a look at this .. it works for me.

(command "._-layer" "filter" "new" "group" "" "YOUR_FILTER*" "YOUR_FILTER_NAME" "" "")

YOUR_FILTER* = put your filter wildcard

YOUR_FILTER_NAME = name of filter - will become current
