Alright, I have this wonderful idea(again) but I can't seem to get what I want done to happen in hammer. I have this pipe/tunnel I have madeclick on the image for a bigger size) - - As of right now it is horizontal in all ways shapes and forms. This is what I want it to do: But! I still want to have the ends square, like this: I've tried to use vertex manipulation and all I keep getting this error every time I move a vertex even the slightest bit: If the 2 ends aren't squared up they will not fit in the doorways I have made for them. The only way they will line up is if the ends are as they were before I put the slope in. Basically is there a way just to slope the middle of the pipe/tunnel and not the whole thing? Or ANY way possible to accomplish what I am trying. I'm hoping I made this problem descriptive enough. I added quite a few pictures cause those are worth a thousand words. Lol. And without them this post would be (obviously) 6,000 words long without them. Thanks to all that can help me with this problem of mine.
