Drawing 3-dimensional shapes

For the past few posts, I have been using simple rectangular shapes to create drawings and structures. As I continued to draw structures, I started to learn techniques in drawing curved objects with round corners. I soon also learned how time consuming drawing 3-dimensional shapes were. To show a simple example of drawing a complex 3-dimensional shape, I started off with a rectangular prism. Scott Robertson and Thomas Bertling states that "a useful way to think about these types of section drawing is that they are 'working drawings' and can endlessly massaged and modified into new forms" (88). Using the rectangular prism as a base, I used ellipses to create round corners for the prism. I divided the inside of the prism to create a hollow shape by creating another prism inside the original prism.

I used the outline to clean up drawing by taking a clean sheet of paper and sketching over the outline. I added some minor shading to give the sketch some dimension. Taking the time to review and practice the basics is necessary to be able to master drawing complex volumes (Robertson, and Bertling 81). It has been said many times throughout the book about the importance of practicing techniques and drawing exercises. I have learned many new techniques but if I wanted to be as good as the authors of the book, I would need to practice many for many years.

Is it more important to draw accurately and if it is, would you take the time to practice drawing accurately?
