Trapeziod walls

[KHaebi]

Is there a feature that enables me to draw trapeziod walls for octagonal buildings and walls?

No, you can slope a wall along its length but not its width. You can't even incline a wall to one side.

My suggestion is that you add trapezoidal-based walls as furniture, altho you'll be missing the important features of using walls (easy window/door installation, joining other walls, etc). There is a feature to create simple cube type structures like you describe under "Generate 3D shape"...
