How To Model Complex Geometry in SketchUp

For complex shapee Rhino 3d does sound like a better modeler, but you can do in SketchUp. Yf you want to wrangle it in SketchUp, divide and conquer is the game. Create clear plan and elevations. Narrow down the base profile curves and approximate the outer form. Make sure to use groups. When you have a solid set of curves, you then can start building the shell. The windows and surfaces can be configured after. It would definitely help to have sketchbook in process.
