Google SketchUp Cookbook phần 4

Tranh một nhóm như thế này có hai lợi thế: nhanh (một cú nhấp chuột), và phải đối mặt với cả mặt trước và sau được sơn. Điều này là hữu ích khi sử dụng một nhóm hoặc một thành phần để cắt, bởi vì bạn có thể dễ dàng xác định khuôn mặt của mình sau khi cắt được hoàn tất. Tất cả điều này được thể hiện trong chi tiết, công thức 6,5. | 3. Copy one of the side faces of the box to the end of the arc. On this face draw a cross-section for steps Figure 4-65 . Figure 4-65 4. Using all three segments of the arc as the Follow Me path and the step section as the Follow Me face create the steps Figure 4-66 . Figure 4-66 5. On the back of the box make a face like the one indicated in Figure 4-67 using tangent arcs. Figure 4-67 6. The Follow Me path for this face is another extended path going past the back of the tub steps so the curved walls will be easy to trim behind the steps. Select all of the top edges of the box as the Follow Me path not including the edge along the back face and run Follow Me on this face. This creates the curvy walls of the hot tub. If you have extra vertical faces around the tub erase them Figure 4-68 . Figure 4-68 7. Run Intersect with Model on the entire model and trim the walls and steps that extend past each other Figure 4-69 . Because the paths for these objects were extended trimming is easy. Figure 4-69 100 Chapter 4 Advanced Intersect and Follow Me Techniques Figure 4-70 Figure 4-71 Figure 4-72 Figure 4-73 8. The last step is to fill the tub with water. The easiest way to make a face to represent the water level is to make a simple box next to the hot tub at the height you want for the water. Remove all but the top face of this box and move edges until they intersect the tub Figure 4-70 . 9. Intersect and trim. You can paint this face with a translucent water material from the Water category Figure 4-71 . Other Uses The extended path technique can be applied to window frames. This section shows two examples of such windows a stained-glass window that you might see in an old church and a more modern three-paned window. Stained-glass window Figure 4-72 shows windows whose frames have two parts created using two separate Follow Me faces. The Follow Me paths are extended past one another and each Follow Me face is a group. After both Follow Me face groups are extruded along .
