Nếu bạn chọn trước con đường, con đường không phải chạm vào phần. Ví dụ, chúng ta sẽ tạo một con hào xung quanh tòa nhà (một điều rất hữu ích không có nghi ngờ). Tạo ra một phần hình chữ nhật với một cắt hồ quang. Trong nhóm, phần là lái xe xung quanh đầu. | Intersect and Follow Me 25. When using Follow Me on a group you need to pre-select the path. So select the top face or select its edges. 26. Activate Follow Me. The section to drive is within the group so right-click the section and select Edit Group. 27. Select the face. Within the group the section is driven around the top. 28. Right-click outside the group and select Close Group. The top looks like it did before . . . . . . but if you look inside you ll see that the vertical walls of the room remain unchanged though you can see the outline of the group. 29. If you pre-select the path the path does not have to touch the section. As an example we ll create a moat around the building a very useful thing no doubt . Create a rectangular section with an arc cutout. 30. Use the bottom face for the path. If you select this face as opposed to the edges be sure to first heal it into one face. 83 the SketchUp Workbook Version 5 31. Select the moat section. It remains the same distance from the path all the way around. However the intersections between the straight and curved portions are not clean. 32. To find out why undo the last action. Use Offset on the bottom face to create the surrounding edges. Stop at the moat section s far endpoint. Here s the problem - the intersections here are not clean either. 33. Extend the lines to meet the arc segments and heal the face. 34. Now use the edges of this face for the moat section. Much better. Follow Me with Components The previous exercise showed how you can avoid stickiness with Follow Me by using groups. You can also use components for the same effect with the advantage that you can reuse sections repeatedly. A good example is the use of moldings. 1. Start with a box and remove the floor so that you can see the moldings. 84 Intersect and Follow Me 2. Draw a molding section on the outside of the box. 3. Use Follow Me on this section along the top of the box. This cuts material from the top of the box but doesn t create a .
