The three-view multiview drawing is the standard used in engineering and technology, because often the other three common views are mirror images and do not add to the knowledge about the object. Front view the one that shows most features or characteristics. Print out your drawing and fold the views into their correct relative locations. RID Explode the block. Axonometric drawings are classified by the angles between the lines comprising the axonometric axes. Print the exam on legal sized paper (8.5" x 14") for best results, though the resource can be scaled to standard computer paper. Bottom view shows what becomes the bottom of the object once the position of the front view is established. Orthographic projection is distinguished by parallel projectors emanating from all points of the imaged object and which intersect of projection at right angles. Orthographic multiview projection is derived from the principles of descriptive geometry and may produce an image of a specified, imaginary object as viewed from any direction of space. Extending to the 6-sided box, each view of the object is projected in the direction (sense) of sight of the object, onto the (opaque) interior walls of the box; that is, each view of the object is drawn on the opposite side of the box.
