Hey everyone. I'm fairly new to map making in hammer, however I do know other 3D modelling tools and the knowledge seems to have been easily applied to some basic areas of hammer. I'm looking at creating a map that is set on the top of a dam (hydro-electric) however one thing I'm struggling with is the actual play area. It needs to be curved like a dam, but all my attempts thus far have failed miserably. I tried to create an arch, but that gives a too rounded dam. I decided to clip off the smallest bit from the top of it, but that only leaves me (with 128 sides on the original arch) with 3 sides. I'm curious - is there a way to manipulate the object in such a way that the end result isn't so rounded? Below is a draft map design (feel free to comment on that too, if you can understand it) that shows the basic shape of the dam. Draft Sketch: Hammer: Zoomed into the top, getting that shape I need: It pretty much end up with me not having enough detail.
