Noob question - how to edit doom 2 maps in UDB?

[LukeGaming]

I've looked through DOOM2.WAD and I can't find any WAD files, only those map maker things:

 

Google only shows me tutorials on how to make maps in UDB and I already know that.

Actually, skim through this handy series of tutorials, it should help a new mapper a lot:

 

 

Thanks, but as I said - I already know map making basics, I just couldn't figure out how to open default doom maps.

 

I found answer in the comments here:

For reference, the two easiest ways are;

1. Copy the entire map out the wad and save it separately in a new wad using SLADE then open it in UDB.

2. Open the original DOOM or DOOM II wad in UDB and just select the map from the list. Best to make a new wad in SLADE first though, because you can't save to the original DOOM wads.
