Concept sketching is a spontaneous representation of ideas on paper without the use of technical aids. Used very early in the design process.
When designers produce freehand sketches they often include brief notes or annotation to help explain the thinking behind the visual image.
Formal drawing techniques tend to be used in the development phase of a design process. Formal drawings are used to represent a more resolved idea. Traditional formal drawings include orthographic projection, assembly drawings / exploded views, isometric and oblique representations.
'Concept sketching- thinking with a pen'
The Designer will use a range of freehand drawing techniques in the early stages of developing design idea to explore, shape, as well as information about construction, relationship of parts. Techniques might include:
Perspective, 2-d drawings [front side + top views], exploded views, tone, shade and sometimes rendered perspectives.

Then work through THIS video and sketch and sketch the product using the techniques developed in the previous presentation. Evidence must be shown and uploaded
Designers work with both 2D and 3D graphical models. 2D models represent detail, proportion, measurements, and relationships.
These can be considered "flat views" of an object
Orthographic drawings show all the details and dimensions of an object, and are typically produced at a high level of fidelity (detail).
3D graphical models show how design might look. Their purpose is to communicate a sense of proportion, scale, and aesthetics. 3D graphical models can take several forms depending on their function.
Both 2D and 3D graphical models typically include annotations in the drawing. Annotations are used to
record thoughts about features of a design
clarify function, material, or purpose of features
identify possible areas for improvement/modifications
Overall sizes (not specific at this stage), possible colours
It is expected that your sketches include annotations
Work along with this and develop your sketching and rendering techniques
Using the skills developed here you can run through the 'Matchbox Exercise'
