1 增强版场景模式 Enhanced Scenes An enhanced scene can be seen as an alternative view of an assembly in a defined state. It enables you to study a variant of your mock-up by defining specific component positions and specific attributes. Component Positioning (using compass manipulation, snap or explode commands) Component Graphical attributes (color, transparency, line type, line thickness) Node Activation state Component Hide / show state Viewpoint 场景增强模式可以对同一个装配里的零部件指定不 同的位置和属性，特别是机构零件，可以浏览不同 的工作状态。 零部件位置（可通过“罗盘模式”，“捕捉模式”，“爆 炸模式”得到不同的零部件位置）； 零部件的图形属性（包括颜色，透明度，线型，线 的粗细）； 节点的激活状态； 零部件隐藏/显示状态； 视图观察点。 场景增强模式的一大益处在于可以对同一装配营造 不同的数据应用场景，而通过装配与场景之间的关 联性可对场景进行调整。 应用之一：在对装配爆炸图的绘制时可以使用不同 的场景进行投影，从而得到不同的效果，而不影响 装配结构。注意首先创建一个全局模式的场景，该 场景可以用来恢复原始装配。 One of the major benefits of Enhanced Scenes is that the applicative data container will be available and functionalities associated with the applicative data will also be available in Enhanced Scene context. It will be possible to generate Enhanced Scenes from Old Scenes. Overloading of attributes (graphical, show / no show state, etc.) is limited to Products, i.e. these modifications are not replicated between scene and assembly for Products, however, for parts, models and manikins these modifications will be replicated (modifications on parts, models and manikins are always replicated in both directions). Likewise, modifications in Enhanced Scene context to Product attributes that are not in the above list (of attributes that can be overloaded) will be replicated on the assembly. 2 增强版场景模式 Enhanced Scenes Overload Mode Full When you create a Enhanced Scene in Overload Mode Full, all attributes are immediately considered overloaded. All subsequent modifications to the Assembly will have no impact on the Enhanced Scene and vice-versa. If you choose to apply the Enhanced Scene context on the Assembly or to apply the Assembly context on the Enhanced Scene, after the operation, all attributes will still be considered overloaded and subsequent modifications to either the Enhanced Scene or the Assembly will continue to be independent, one from the other. Overload Mode Partial When you create a Enhanced Scene in Overload Mode Partial, by default, none of the attributes are considered overloaded. Modifications to the Assembly will impact those attributes of the Enhanced Scene that are not overloaded (so, for example, if you make some modifications to the Assembly immediately following the Enhanced Scene creation, all of these modifications will impact the Enhanced Scene). Modifications to the Enhanced Scene never impact the Assembly, the result of such modifications to the Enhanced Scene is to overload the modified attributes. Attributes in the Enhanced Scene are overloaded implicitly when you modify the attribute in Enhanced Scene context. 场景增强一般有两种模式：全局模式和局部模式 全局模式：一旦创建全局模式后，所有的属性将 被认为是“过载”。对装配的任何后续修改不会对场 景产生影响。场景里的任何修改也不会对装配产 生影响。那些属性都依然保持“过载”状态。 局部模式：在局部模式下，属性不再被认为是“过 载”。装配里的修改会对场景里的未“过载”属性产 生影响。反过来，场景里的修改不会对装配产生 影响，但一旦修改，这些属性将变为“过载”。比如 颜色属性未“过载”，则在主装配里修改颜色，则会 直接反映在场景里。 3 增强版场景模式 Enhanced Scenes 全局模式 局部模式 爆炸视图 视图观察 点 过载位置 过载隐藏/显示 过载属性 过载节点激活 Once the scene is created, it is not possible to change the overload mode; nevertheless, it is possible to create a new Enhanced Scene from an existing Enhanced Scene and to affect a different overload mode to the new Enhanced Scene at its creation. 场景创建后过载模式将无法更改，不过可以根据 现有场景重新创建一个新的场景，再赋予不同的 过载属性。 在场景模式下，可进行如下操作： 创建爆炸视图 记录视图观察点 进行过载属性设定，包括位置，隐藏/显示，属性 ，节点激活等四项 过载属性设置可以赋予场景中的零部件与装配里 不一样的属性 场景模式下的视图背景色设置： Tools Options DMU DMU Navigator settings 4 增强版场景模式 Enhanced Scenes 对场景大图标双击鼠标有如下3种执 行方式： 激活该场景 将该场景应用到装配中去 应用用户定义的属性 5 “装配”的初始状态 过载局部模式 过载全局模式 增强版场景模式 Enhanced Scenes 移动装配里的一个部件 移动后的局部模式 部件跟着移动 移动后的全局模式 部件未移动 在场景里修改为粉 色，则该颜色属性 被认为已经“过载”， 装配里不会跟着变 为粉色。 在场景里修改为绿 色，则该颜色属性 被认为已经“过载”， 装配里不会跟着变 为绿色。 两种场景模式的差异。 6 增强版场景模式 Enhanced Sc
