使用图块、群组与工作会话

图块、群组与分工运行都属于模型元素的组织方式。

使用图块

图块是模型中被看作一个物件的已命名的物件群组。当需要重复物件（如作为符号或部件）时使用图块非常有效，需要重复物件时，您可以重复使用图块，而不用去重绘，从而可以节约您的时间，使用图块来重复物件还可以节约内存，此外，当您重新定义一个图块时，场景中所有此图块的实例都会同时更新。

Define a block object.

Allow selecting a block instance to change the block geometry and update the block definition.

Opens the Block Definitions panel for managing the block definitions in the model.

Copy a linked block with Reference style layers.

Explode a block including any nested blocks into component objects.

Save selected objects to a new file.

Save objects to a new file with a specified origin and construction plane.

Insert block objects stored in the file or import a file as a block definition.

Set a world origin that is used when inserting the model into another.

Replace block instances with a different block definition.

使用群组物件时，当您选择群组中的一个物件，将选择整个群组，群组的结构可以是嵌套的，群组也可以被命名。

Organize objects into a single component.

Add an object to a selected group.

Detach objects from their parent group.

Remove the group status from objects.

Name a group.

分工运行可以让多个用户通过参考引用的方式同时进入同一个模型。一个分工运行就是一个当前开启模型中可见、可锁定以及其他可以作为引用参考操作的列表。

Manage a list of models that can be used as reference geometry.
