Lsp to create groups by layer, with layer name as group name

[Oni]

Morning All,

 

 

Habitual LT user here - so no lsp before. Been given 2 month access to a 2014 license to get this job out of the door.

 

 

I'm trying to create a lsp that grabs the content of a drawing, selects objects by layer and groups them using the layer name as the group name. I've found a couple of lsps that do some of what I want so I've been pulling them to bits and trying to create what I need, but I'm stuck.

 

 

I've managed to get to a point where I've got a list of the layers and start the group command but I cant get the group names to work.

 

 

I'm not demanding a full lsp, but would very much appreciate some guidance on how to approach this one.

 

 

I've gone through the tutorials on Afralisp and some of the other threads but I just don't seem to be making any progress.

 

 

There's 41 layers in most of these drawings, I don't really fancy doing it manually...

 

 

PS I cant access any of Autodesks online help as apparently our IT guys have classified it as an "unsafe site".
