This is a first time sketching a product like this, that has quite difficult shape due to angled circles and many small details. So, today I tried to create some doodles of a racing wheelchair – these are my scribbles that I made while exploring the shapes this product is made of.
While looking at some pictures of a racing wheelchair, I took a ballpoint pen and started to create fast sketches and hoped that in the end it will look like a racing wheelchair. The hardest part was to draw angled circles that in the perspective were ellipses. As you know, that ellipses and I are not quite best friends, so I tried to do my best.
After these kind of doodles, the next step is to create more detailed and precise sketches.
