Walls? And unit types for players

[LegendsEnd]

I just started playing around with world edit so there will probably be many questions to come, but these are the ones i've run into right now. Are there any wall structures? Like Building a wall around something to encase it, or something like a brick castle wall that I can span across the map, secondly, It's pretty annoying to change the players unit type to put in different units, is there an option I can turn on so I can select units from every race regardless of what it is under the player options? Also is there anyway to select the units after placement? So I can see it's hp/dmg/etc

Thanks for any help in advance

u can already select and unit with any color using the little sub window thing u know were it shows land sets just switch it to units go to race and change that to whatever race, hope that makes sense and the second thing just use land set with a high land, probably makes no sense

There are no "melee" wall units. The Fence Doodad is an unpathable, long barrier, though, so you could use that. Otherwise, make a custom unit based off a farm, make it produce 0 Food, and change its graphic to a Scout Tower. I'm using that sort of thing for one of my maps
