多标签工具

Sketchup 的扩展在开发复杂模型时可以更灵活地控制对象的可见性，例如房屋、带有工程网络（供水、电力等）的公寓，增加了为实体分配多个标签的能力，并使用多个标签之间的逻辑公式控制可见性标签

默认情况下，所有选定的标签都使用 AND 条件：因此只有在启用所有标签时才会显示对象；

扩展还允许在层之间使用 OR 条件，分组和组合 AND 和 OR 条件

例如：房屋中的每一面墙都可以至少分配给两层“room1”和“room2”，并且在启用“room”标签之一时可见，或者家具可以同时属于标签“room”和“type”，例如“椅子”或“桌子”，仅当两个层都处于活动状态时才显示

The extension for Sketchup get more flexible control the visibility of objects when developing complex models, such as houses, apartments with engineering networks (water supply, electricity, etc.) adding ability to assign to entity multiple tags and control visibility using logical formula between several tags

By default all selected tags use AND condition: so object will displayed only if all tags are enabled;

Extension also allow use OR condition between layers, grouping and combination AND and OR conditions

For sample: Each wall in house can be assigned at least to two layers “room1” and “room2” and be visible when one of “room” tags enabled or Furniture can belong to both tags “room” and “type”, for example “Chair” or “Table” and are displayed only when both layers are active
