This is such type of projection in the drawing of which such projectors are drawn, which are at some angle other than 90° with the plane.. Generally, one view of the object is made parallel to the plane. The line type is phantom and the line weight is very thick (0.6 to 0.8 mm). Orthographic Projection is a way of drawing an 3D object from different directions. Orthographic projection technique can produce either pictorial drawings that show all three dimensions of an object in one view, or multi-views that show only two dimensions of an object in a single view. Conventional Orthographic Views Height Depth Width Front View Top View/Plan Right Side View 15. orthographic. Orthographic projection is a way of showing a three-dimensional (3D) object in two dimensions (2D). Orthographic drawings are useful especially when a design has been developed to a stage whereby it is almost ready to manufacture. The drawing will also show what objects look like from different viewpoints. The isometric drawing is a type of piping drawing and it shows the piping system in three dimensions (length, width, & depth). It's a kind of parallel projection where projection lines are orthogonal to projection planes.
