I have Warband 1.153,

and I have replaced the native singleplayer siege tower with the more real looking siege tower from multiplayer WB, and have got it to work,
but i can see that editing the AI mesh is going to be a bother,

does anyone have any helpful shortcuts?, or does anyone care to help me with this?
I am a veteran player/modder, I just am new to Edit Mode. (and the forums i just got my email to work)
P.S.: How do you weld two faces together?????????
P.P.S:IF YOU CAN HELP, PLEASE DO! I DON'T HAVE ALL YEAR!!!
