How to recreate a 3D model from a sketch.

hi. i use autocad in 3d modeling. :) in this particular object. you will be using loft and sweep command. I suggest that you make orthographic views first. take note of the surfaces that will be lofted/sweep and should be provided with path(s) and guide(s) for better results.I highlited some for you to see what Im talking about. The blue and red lines are the surfaces you will loft/sweep and the yellow lines will be the path/guide that will take shape of the 3d model. Good Luck :)
