It's hard to create a drawing that is just a screen image. But it's possible, add a photo to your Autocad screen, freeze photo layer it. Draw 2d drawing, after 3d drawing create from Solidworks. Draw a line across the boundary lines of the photo.
You need a reference meter. You need information for a measure such as height, thickness. For this piece in the picture. When finished 2d drawing scale it, for curent dimension.
