Help needed to created a curved 3d model using Google Sketch

Hi this is my first time on here. I have never used a 3d program before and I'm trying to create a model of a space ship based on a 2D concept for a 2D animation. I have got the gist of how to use Sketchup. The problem is I can't pull or push spaces on curved surfaces. I have watched the video tutorials and there is not anything about this.



I would really appreciate any help. Thanks

You can not do it in sketchup from what I know.
But you can edit the arcs with move tool to edit some surface that a based of them. In general sketchup lacks a lot of tools needed for detailed 3d modeling.
