3D manufactorting drawing
Manufacturing drawings are often flat 2D drawings and work well for some designs but for some castings and other manufacturing styles, 3D is just better.
looking online there is little too noninformation on having a 3D drawing is done. Most of the time an image of the 3D model is captured and then imported into a vector graphical program and then drawings dimensions are then done there.
From a Facebook post related to beginners for trying to model the part. I found the inspiration to do my take on a 3D drawing.
