Drawing and Developing Plans in Industrial Technology

Sketching This technique is about getting your ideas on paper. Remember it does not have to be neat or accurate but have all the possible ideas that you want to convey to the viewer. Use continuous straight lines Go over the lines with felt tip pens to enhance it and its features Add hatching and shades to further enhance features Add shadows to bring it to life Remember to add basic measurements and annotate details so the viewer what each part is

Working Drawings The following 4 working drawing plans should be in your Major Project Folio Orthographic Projection (Orthogonal) Isometric (Pictorial) Oblique (Pictorial) Exploded or Assembly Drawing (Pictorial)

Orthographic Projection (Orthogonal) Orthographic projection is a drawing that displays a number of 2D faces of an object to scale, usually Top, Front and Side. It allows the viewer to visualise the faces of the object, and how they are linked and projected off one another. They also allow all measurements, notes and hidden detail to be displayed. Remember: Must have a Top, Front and Side face All Measurements and Details need to be annotated Must be to scale Must line up and project off each other Hidden Detail need to be shown Opposite to Pictorial.

Isometric (Pictorial) Isometric is a form of pictorial or 3D base drawing that is drawn to scale on a 30 degree plane. It allows the viewer to see an accurate projection of what the final product will look like. Remember: Lines are either Vertical or at 30 Degrees Must be drawn to Scale

Oblique (Pictorial) Oblique is another form of pictorial or 3D base drawing that is drawn to scale but on a 45 degree plane. It allows to viewer to see an accurate projection of the final product but the projection of the product up the 45 degree lines need to be halved. Remember: Must have a front face Lines are either vertical, horizontal or at 45 Degrees Must be drawn to Scale The projected 45 degree lines need to be halved

Exploded or Assembly Drawing (Pictorial) Exploded or Assembly Drawings are another type of pictorial drawing usually completed in Isometric projection but with a few small differences. First they show a part or even the complete product in pieces to show how all components come together to form the complete product, thus providing the term exploded. The pieces are also usually numbered to coincide with a parts list (Cutting List) on the page to indicate what each part is and the exact sizes. Remember: Pieces are not joined so as to indicate how it all forms and comes together Parts lists is given to indicate all sizes Usually drawn in isometric projection
