One of the technical skills which we have been able to practice and learn in Design Technology is 3D drawing. This was demonstrated in my C3, when it was necessary for me to make 6 fully rendered images of our planned product. This also means that I have been able to demonstrate communication very effectively, as it is important in showing a final piece of presentable work, and for it to be understood by the person looking at it and interpreting it. This was done using a pencil, ruler, colour pencils, and a thin and thick marker. Learning to draw isometrically will be super useful for my IB DT course, which I will be taking at an HL level.

Learning to draw fast is also something which was taught, as our IGCSE Paper 1 for DT requires candidates to make 3 rough sketches (with rendering) and one final rendered drawing with full dimensions and very accurate line work. It’s imperative that I show clear communication in the paper, as marks are not only awarded on drawing ability, but the ability to express my ideas across to the examiner. 3D drawing takes about 1 to 1 1/2 hours as line work and shading have to be quite accurately reflected on the final product (as mentioned, this might be hard to quickly in an exam). Proper rendering technique takes into account sunlight angles, curvature of a surface, and intensity and colour of the light; all of which have to be presented on the final render. In the images I will link below, I will demonstrate how I used my 3D drawing skills to carry out C3 and a self evaluation on the product. I had to combine the use of my drawings with annotations regarding how the product will be built (ex. construction methods and material).
