![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
模式将使用源数据集中的级别号和元素生成。Thelevel numbers will be used to create FME feature types as in the Group by Levelselection;然而,属于某一级别的所有元素的属性都将累积起来,并添加到该级别的FME特征类型中。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
将使用源数据集中的名称和元素生成模式。级别名称将用于创建FME功能类型,如“按级别名称分组”选择中所示;但是,属于某一级别的所有元素的属性都将累积起来,并添加到该级别的FME特征类型中。
元素选项
读卡器可以配置为输出组成单元的所有元素,or symbols.如果要保留设计文件的图形表示,则此功能非常有用。这是真的,for example,将设计文件转换为GIF图像。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
选择此选项可将单元格展开为单独的功能。

阅读第一级参考:(已弃用:被参数max depth of reference files to read取代)
读取附加到源数据集的外部引用文件中的所有受支持元素,仅限于第一级嵌套。This parameter is valid only if Read Elements from Reference Files is selected.
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
指定从附加到源数据集的外部引用文件中读取多个级别的受支持元素。Files referenced by the source dataset are considered level 1,嵌套引用被认为是进一步的级别。
This parameter is valid only if Read Elements from Reference Files is selected.
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
此参数仅适用于版本8。
选择时,将附加到源数据集的任何外部引用文件作为具有IGSDS-型属于IGDS-XREF.
注:外部引用文件中所有受支持元素的读取受从引用文件读取元素参数(不是这个参数)。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
选择此选项以显示标记。设计文件中的元素可以附加用户定义的属性,in a form called标签.FME可以读取(但不能写入)这些属性。此外,要为用户定义的属性提供值,tags may also be displayed as text in the original design file.
When reading a design file,FME首先扫描所有标签数据元素和标签集定义元素。Then as it reads each graphical element from the design file,它使用元素关联ID将数据和属性名称与图形元素重新连接。所有的标签数据值都会被添加到返回到FME的特性中。
属性选项
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)

![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
此参数仅适用于版本8。
选择此选项可读取Xattribute信息。设计文件中的元素可以使用名为XAttributes.这些属性可以通过FME读取(但不能写入)。它们表示为列表属性,并包含各种类型化信息块,如XML片段,as is the case when they represent XML-based Feature Modeling (XFM) data.
Linkage Extraction
链接提取框允许您从源设计文件中提取mslinks和/或framme属性链接值。Only the first three linkage values will be extracted.
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
这些链接值可用于将设计文件中保存的图形数据连接到相关数据库表中的mslink字段。提取的实体号用于确定保存属性的相关表(数据库包含一个名为mscatalog的表,该表将实体号映射到表名)。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
UFID与设计文件的基名称一起提取。这两个项目形成一个复合键,可以加入相关的framme数据库。
坐标单位
这些参数控制设计文件中的UORS和FME坐标之间的转换。有三种可能性:
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
注意,对于这些转换,FME特征的坐标将表示按比例缩放的坐标。UOR to FME Units Scale Factor.这些坐标都是相对于工作坐标的。
Coordinate Units Value | 描述 |
Master |
The UORs read from the Design file are converted into master units,根据从设计文件头读取的转换系数,在存储在FME功能中之前。 |
附属的 |
The UORs read from the Design file are converted into subunits,根据从设计文件头读取的转换系数,在存储在FME功能中之前。 |
UOR |
从设计文件读取的UORS直接存储在FME功能中,不进行转换。 |
Override Global Origin
这些参数通常只在读取具有错误头信息的设计文件时使用。If FME detects a difference between these settings and those read from the Design file,将警告输出到日志文件,and these settings take precedence.
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
You can override the global origin,默认位于设计平面/立方体的中心,通过设置x的值,Y,Z.设置这些值将覆盖从DGN文件。有效值是无符号32位整数。
- x:x的全球起源,measured in UORs,从设计平面/立方体的左下角开始。
- Y:Y的全球起源,measured in UORs,从设计平面/立方体的左下角开始。
- Z: The global origin of Z,measured in UORs,从设计平面/立方体的左下角开始。
Schema Attributes
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
使用此参数公开设置属性格式在Workbench中创建工作区时:
- In adynamic scenario,这意味着这些属性可以在运行时传递给输出数据集。
- 在非动态场景中,you can use this parameter to expose additional attributes on multiple feature types.
Use Search Envelope
使用最小和最大x和y参数,定义将用于过滤输入特征的边界框。仅返回与边界框相交的特征。
如果搜索信封的所有四个坐标都指定为0,搜索信封将被禁用。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
选择时,此参数删除正在读取的已导入功能中位于搜索信封之外的任何部分。
The example below illustrates the results of the Search Envelope whenClip to Search Envelopeis not selected (set to No) and when it is selected (set to Yes).
- 否:将读取跨越搜索信封边界的任何功能,包括边界外的部分。
- 是:任何跨越搜索信封边界的功能都将在边界处被剪裁,只读取边界内的部分。的基础函数Clip to Search Envelope函数是一个交集;然而,什么时候Clip to Search Envelope被选中,除交叉点外,还执行剪切操作。
先进的

选择时,复杂链的每个组件都将作为其自身的特性返回,并且整个复杂链不会返回任何特性。
取消选择时,all elements of the complex chain will be merged into a single linear feature,复杂链中的任何弧都将转换为字符串,而构件本身的任何连接都将丢失。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
选择时,the reader splits the multi-text into text nodes and outputs the member text elements as individual text elements.如果多文本具有任何链接属性,这些将传播到组件元素。
取消选择时,文本元素不拆分。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
控制导入维度的方式。
选择时,the dimensions are exploded into its pieces.
取消选择时,the dimensions are imported as an aggregate.当尺寸作为集料导入时,弧被选通,文本特征仅作为列表属性输出。例如,如果您正在执行从dgn到dgn的转换,但未选择此选项,文本功能将丢失。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
如果您有一个ESRI世界文件(*.wld),希望在确定数据集中功能的坐标时使用FME,请选择此参数。
FME will search the folder of the dataset for a file with the same name as your dataset but with a.wld延伸。如果找不到同名文件,it will then look for the file埃斯里卡within the dataset folder.If either of those files exists,FME将使用文件中的信息将数据集中特征的坐标转换为新的地理空间坐标。
如果找不到文件,然后继续翻译,使用数据集中找到的坐标信息,不执行任何其他转换。

此参数控制是否通过添加顶点将曲线元素移动到线条中。
选择时,曲线的控制点连接成一条直线。此选项保留原始控制点和末端坡度。这主要用于从dgn到dgn的翻译。
取消选择时,控制点用于插入曲线的线性表示。It strokes (vectorizes) the curve (that is,it preserves the shape of the curve).Deselecting this checkbox enables the parameter插值曲线顶点数.
