Exercise - side B - process description
Welcome to the fourth week.
Fourth week is starting with more complex drawing. First version of side A is combining ellipses to define rotating objects with different silhouettes. First you need to define a silhouette. Than you start define axis and start than you start placing ellipses on axis whose defines a surface of the object.
Version B of the sheet A is a little bit easier, because is still working in "2D" space. The key is the symmetry. You start with an ellipse. Than you place another ones according to the enclosed picture. At the end you prove the symmetry of the drawn ellipses with two circles (one on the outside of the object and another in the inside).
Side B is about surface, that is defined by a couple of curves. You start with placing a few curves on the paper. Than you need to think about how those curves defines a surface. Than you start placing section lines. I did one version with shading so you can see how this progresses further. Keep in mind that you need to think before you draw.
Recommended number of practise sheets : 20x A3 (cardesigner at least 30x)
- side A can be done either in version A or version B
Good luck in your progress.
