Thay đổi màu sắc của chất rắn đại diện cho các ghế ngồi để cyan, và sau đó chọn thực tế hình ảnh phong cách Visual Styles flyout trên bảng tab Home. Bản vẽ của bạn sẽ trông tương tự như hình ảnh trên bên trái của hình 22,39, trong đó cho thấy một quan điểm xem. Những hình ảnh bên phải là cái ghế với một số tài liệu được giao đến các bộ phận của nó và điều chỉnh nhẹ đến vị trí chỗ ngồi | creating complex 3d surfaces 709 6. Change the color of the solid representing the seat to cyan and then select the Realistic visual style from the Visual Styles flyout on the Home tab s View panel. Your drawing will look similar to the image on the left of Figure which shows a perspective view. The image on the right is the chair with some materials assigned to its parts and a slight adjustment to the seat location. 7. Close the file. You can save it or if you intend to repeat the exercise close and do not save. FIGURE A perspective view of the butterfly chair with tubes for legs Using Sweep to Create Complex Forms Although you used circles with the Sweep command to create tubes you can use any closed polyline shape. Figure gives some examples of other shapes you can use with the Sweep command. FIGURE You can use any closed shape with the Sweep command. 710 chapter 22 using advanced 3d features In step 3 of the previous exercise you may have noticed some command-line options. These options offer additional control over the way Sweep works. Here is a rundown on how they work Alignment This option lets you determine whether the object to sweep is automatically set perpendicular to the sweep path. By default this option is set to Yes which means the object to sweep is set perpendicular to the path. If set to No Sweep assumes the current angle of the object as shown in Figure . FIGURE Alignment lets you set the angle between the object to sweep and the sweep path. By default the object to sweep Rotate the object to sweep to an angle away from the WCS and then turn off the Alignment option. is aligned perpendicular to the sweep path. You can skew the object to sweep in relation to the sweep path by using the Alignment option. Base Point By default Sweep uses the center of the object to sweep as the location to align with the path as shown in Figure . Base Point lets you set a specific location on the object. FIGURE Using .
