yea that was the problem though. in the screen shot you can see that if I change it to the desired 6500 mm then it still doesn't show. I'm really lost here. I have started a new file so many times as well. usually I just draw a wall, type in the height in the object info palette and done. but this time it just won't extrude no matter what. is there a way to maybe reset all settings of vw? or what is the best way to get on with the file?
