autocad map 3d: import .layer file

[francizzz]

fast and direct demand:
Since I have to automate the insertion of the theme style of over 40 shp files you know if there is a keyboard command that allows me to upload ".layer" files into an autocad design so you can create a script or other?

but do you want to load .layer files in autocad or in map 3d?
a script for what?
I'm sorry, but I didn't understand.

I need to upload them to map3d and the scipt to help me "automate" the insertion of those files since I have to do it for more than 40.
basically I have the shape of the municipal territory divided by sheets, I have to theme the various geographical elements (roads, buildings, etc.) and I have to find the way to recall the different themes in multiple designs without having to reconstruct them every time.
Sorry I don't know if I can make me understand. . .
