Hãy cố gắng vẽ một đường ngang từ bên ngoài của xoắn ốc. Bạn sẽ nhận thấy rằng bạn không thể tham chiếu kết thúc của xoắn ý rằng bạn không thể chọn hình xoắn ốc từ cửa sổ đồ họa. Ngay cả khi được chọn từ FeatureManager, nó xuất hiện không được lựa chọn trong cửa sổ đồ họa. | Part III Working with Assemblies Other types of valid in-context relations include in-context sketch planes and end conditions for extrude features such as Up to Face and Up to Body. Beyond that you can copy surfaces from one part using the Knit Surface feature or the Offset Surface feature. I discuss surfacing in more detail in Chapter 27. Working in-context When you are working in-context or using in-context data visual cues offer information about the part that you are working on. The following topics are meant to help you understand what is going on while you are working in-context. Text color When you are working in-context the FeatureManager text of the part that you are working on turns blue. This should make it immediately obvious first that you are working in-context and second which part is being edited. Part color and transparency You can control the color and transparency behavior of parts in the assembly where a part is being edited in-context by choosing Tools C Options C Colors page. Figure shows a detail of this page. The option at the bottom of the dialog box determines whether the colors specified in the list at the top are used or ignored. If they are ignored the parts are the same colors they would be if you were not using in-context techniques. FIGURE Part-color settings for in-context control 546 Chapter 16 Modeling in Context The Tools C Options C Display Selection Assembly transparency for in context edit controls the transparency of the parts not being edited. Figure shows this setting. Forcing the non-edited parts to become transparent helps you keep focus on the part you are editing in the assembly. FIGURE Part transparency for in-context control The options in the Assembly Transparency drop-down list are Opaque Assembly. All parts that are not being edited when an assembly component is being edited in-context turn opaque even if they are otherwise transparent. Maintain Assembly Transparency. Leaves all assembly .
