tailieunhanh - Ebook How to draw: Part 2

Part 2 includes 05 chapters. Early chapters explain how to draw accurate perspective grids and ellipses that in later chapters provide the foundation for more complex forms. The research and design processes used to generate visual concepts are demonstrated, making it much easier for you to draw things never-before-seen! Invite you to consult the documentation. | CHAPTER P A WORKING WITH VOLUME If you are most interested in drawing difficult symmetrical forms accurately in perspective then this is the key chapter to study in this book. This chapter will break down and explain all of the most used and helpful construction techniques we know of to increase knowledge page-by-page until at the end of this chapter almost any form can be accurately drawn in perspective. We have observed with our students over the years that by tackling one facet of volume-building at a time and only moving onto the next level of complexity after each previous lesson was mastered their understanding of form-building from their imaginations was greatly improved. All of the knowledge gained so far in this book will be used so if earlier steps were skipped this chapter may quickly become frustrating. Don t despair and throw this book across the rooml Take a deep breath pause turn back to the section where more study is needed and review it again having gained insight of how important the early basic exercises are to success in this chapter. At the center of accurately drawing volumes in perspective is an understanding of drafting which is the skill of drawing the same object from multiple views without any perspective convergence. This might seem counterintuitive but the way we are going to teach you to draw is very much like drafting multiple views of an object simultaneously in perspective. Taken step-by-step this method can become second nature in your drawing. After the ability to think up forms in a draft view is mastered we will work in perspective and start to build out the form using sections drawing on the X Y and z planes as defined by the perspective grids and guidelines. The accuracy of your curved surface volumes will be directly influenced by your ability to draw straight lines and to plot points using those straight lines. X-Y-Z section drawing is the core skill necessary to master drawing complex volumes such as the vehicles in later
