I’m trying to model the front part of a vehicle in threejs which has three inclined planes, one at the front and two oblique ones at each side:

- Top view

- Iso view

It’s easy to model the front-middle part extruding a shape like this:

But I am having trouble on how to make the side parts, the only solution i could think of is making an extruded squared/rectangular mesh and trying to slice it with a plane (i’m guessing there is a way to do this somehow on threejs) but maybe there’s a better way to do this.
