Drawing Problems - Chapter 9 Copyright Goodheart-Willcox Co., Inc. Chapter 9 Mesh Modeling 235 5. Architectural In this problem, you will create a home theater chair as a mesh shape. Change visual styles as needed throughout your work. A. Set the tessellation divisions for the box primitive to length = 5, width = 3, and height = 2. B. Create a 3 × 2 × 1.5 mesh box primitive. C. Move the top-back edges (short side) up 1 unit and the top-front edges down .75 units. D. Crease the one face in the middle of the top, then move it down 1 unit, as shown in A. E. Crease all faces on the bottom. F. Smooth the model to level 3. G. Nonuniformly scale the middle face on the top, which is now circular, to create an elliptical shape. Then, move the face .5 units toward the chairback. H. Move the three top edges on the front .5 units toward the chairback. I. Move the middle face in the front top down 1 unit, as shown in B. J. Rotate the top three back edges 45° to create a sloped chairback. K. Move the single edge in the middle of the back inward .5 units, as shown in C. L. Increase the smoothness to level 4. M. Save the model as P9-5.
