In this video we will take another subscribers scan (sorry can't share) of an NC(third gen) Mazda Miata MX5. Since this is something we have already done we will take a new approach. First we need to clean the mesh, and use Forms to replicate the area of the trunk lid that we need for the spoiler. Then use that forms surface to begin to build out a spoiler with surface tools. Sometimes building what you can with surfaces will be a better option.
Also note there are mesh sketches are an option BUT in this case using forms to build the truck is a much more elegant solution.
