I'm really new to Blender, and I was trying to build a castle wall. The only way that I could figure out how to do that was with a bunch of cubes. I've built the castle, figured out how to animate the drawbridge, and added some not great color. Now I'm trying to figure out how to round out everything so that this tower thing looks more like a tower and less like a stack of cubes, and the window things to be kind of arched at the top, not just cubes. What's the best way to do that?
You don´t need to do that. Just use a cylinder for the tower. Select the upper face and extruded out to extend it a little and then extrude it up to give heigh.Make two loop cuts one outside and one inside the extruded faces to create a division for the up and down wall ( i don´t know the exact name of that part) Then jus select the faces you need to make the upper part of the tower and erase them. After that select the edges of the adjacent face and click on keyboard F to fill it with a face.
