Lisp Routine for Thawing Layers then Freezing specific Layers

[kcharette]

I would like to know how to write a routine to thaw all layers in current drawing and multiple xrefs; then freeze all, then thaw only certain layers globally for a drawing that is open.  Such as a dimension plan will thaw only *-BLDG, *-DIMS, *-RD-*, *BNDRY.

I would like to create one that will fit every project which has a different xref name.

You'll likely get more responses for this in the Customization Forum.

Have you looked into whether "Layer States" would accomplish what your after?

They would be per project given the variable xref's but once set are pretty quick.

I've never had much luck with layer states but they would seem to provide a potentially simpler solution for this...
