Autodesk AutoCAD Realdwg DWG/DXF读取器参数

该架构将使用源数据集中的层作为FME功能类型生成。

The schema will be generated using all the possible AutoCAD geometry types as FME feature types. This list is set by the reader capability and is not limited to geometries which occur in the given source dataset.

The schema will be generated using both the layers and entities in the source dataset. The layers will be used to create FME feature types as in the Group by Layer Name selection; however, the attributes of all the entities belonging to a layer will be accumulated and also added to the FME feature type for that layer. For Extended Entity Data attributes to appear, the reader parameterRead Interpreted Extended Entity Data必须选择。

选择后，此参数会爆炸块并返回形成块组件作为单独功能的实体。

当读者解决块时，它会为每个属于块定义的一个自动AutoCAD实体输出功能。The original insert is not output. This results in the full graphical representation of the block transferred through FME, but the exact insertion point of the block is lost.

Each block member feature is given the attributeautocad_block_number这是设置为相同的值为每个块that the features comprising each block may be combined in subsequent processing. Arbitrary deep block nesting is permitted, however, theautocad_block_number属性仅在最外面的每个块更新。默认情况下，所有块成员都将与原始块的成员放在同一层上。

指示AutoCAD阅读器有关实体扩展字典中XRECORD条目的阅读。这些Xrecord条目可能会相应地成为FME功能属性。

如果未选择（默认值），则不会读取任何Xrecord条目。

如果选择，Xrecord数据将成为类似于列表表格的FME功能属性扩展实体数据，但具有带有表单名称的属性autocad_xrecord_data*。

创建工作空间时，请使用此参数在Workbench中公开格式属性：

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• 在您拥有多种功能类型的非动态场景中，使用此参数揭示其他属性很方便。例如，如果您有十种功能类型，并且想要在每个功能中公开相同的属性，那么定义一次的特征比在工作区中单独设置每个功能类型要容易。

使用最小和最大X和Y参数，定义一个边界框，该框将用于过滤输入功能。仅返回与边界框相交的功能。

如果将搜索信封的所有四个坐标指定为0，则将禁用搜索信封。

选择后，此参数将删除读取搜索信封外的任何导入功能的任何部分。

下面的示例说明了搜索信封的结果Clip to Search Envelopeis not selected (set to No) and when it is selected (set to Yes).

• No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
• 是：任何跨越搜索信封边界的功能都将在边界处夹住，并且只有在边界内部的部分才会被读取。的基础功能Clip to Search Envelopefunction is an intersection; however, whenClip to Search Envelopeis selected, a clipping operation is also performed in addition to the intersection.

Determines whether to resolve the entity's color, or keep it asByLayer。When selected (which is the default), theautocad_color属性将按值包含实际颜色（0到255之间的整数），因此保留原始属性。

例如，如果您在“河流”层上有一个实体，其颜色设置为ByLayer， 和the layer color set to "blue":

• 如果选择此选项，则autocad_color属性将设置为"blue" (its equivalent integer value).
• 如果您不选择此选项，则autocad_color属性将设置为ByLayer(an integer value of 256) and the components will all be assigned the same layer color.

Usual AutoCAD-to-AutoCAD translation setting:未选中的

指定是否以保持其复杂性能的方式读取孵化和mpolygon。

如果选择了此参数，则循环将作为多边形汇总在一起，并进行排序，以便在任何封闭的循环之前都存储任何封闭的循环。可以将属性添加到存储polyline Bulge Arc信息中。

Usual AutoCAD-to-AutoCAD translation setting:Selected

Specifies whether the reader should leave a raster unclipped and only store the clipping information as attributes, or whether it should apply the clipping.

• 如果选择，则不会剪切栅格，并且可以从功能属性中检索剪辑信息，这允许剪切的光栅功能通过FME，而不会丢失数据。
• If not selected (default), clipped rasters being read will have their clipping information applied, and anything outside the clipping bounds will be lost.

Usual AutoCAD-to-AutoCAD translation setting:Selected

指定是否要分解（爆炸）尺寸到其各个部分中。

If selected, each geometric piece of the dimension will be output as a separate feature, as well as a non-geometricautocad_dimension_def特征。

如果未选择，将输出包含原始维度所有片段的聚集体（即autocad_dimension).

Usual AutoCAD-to-AutoCAD translation setting:未选中的

确定如何阅读多行实体。如果未选中，则通过仅包含基线的显式顶点和附加线的相对顶点的线构建多行几何形状。检查后，对多行属性进行了其他评估，这可能会导致几何形状中的其他顶点和间隙。评估的几何形式是多行实体的更完整的几何表示，但不能由AutoCAD作者丢失而写。

选择后，AutoCAD读取器除了将花纹矢量化外，还将样条系数存储为属性。

看the description of花键对于用于存储样条定义的属性名称。

Usual AutoCAD-to-AutoCAD translation setting:Selected

When selected, the AutoCAD reader doesn’t vectorize the Polyline and LWP Line Bulges but rather just stores the coefficients in the attributeautocad_bulge。

另外，当指定时，此参数允许创建autocad_start_width和autocad_end_widthattributes to represent the width properties of Polyline and LWP entities.

Usual AutoCAD-to-AutoCAD translation setting:Selected only when performing AutoCAD-to-AutoCAD translations

Instructs FME to ignore the user-defined coordinate system of the file being read. By default, FME applies the UCS when reading the coordinate data.

If the feature becomes a point, it will still retain all the attributes it had while it was an arc.

Usual AutoCAD-to-AutoCAD translation setting:Never selected

确定是否会读取AutoCAD组。默认情况下，FME不会读取组。

Determines whether or not AutoCAD xrecord data will be read from the dictionaries in a drawing. By default, FME will not read these XRecords.

This option creates non-geometricAutoCAD_XRECORD具有类似于使用的属性的功能Entity XRecord Data Reading选项。

确定FME是否会读取代表外部引用的AutoCAD实体。默认情况下，FME不会读取外部引用。

If you select this option, the AutoCAD Reader will add additional attributes describing the layer properties for the layer of each feature. These includeAutoCAD_LAYER_LINETYPE,autocad_layer_color， 和autocad_layer_lineWeight。

在输出任何其他功能之前，读者将在翻译开头的所有块定义输出。输出块后，其余的翻译将运行，而无需解决块。

此值覆盖了指定的值爆炸进入实体。

When selected, all features that are part of a block definition have the attributeautocad_block_definition, with the value of the attribute being the name of the block which they are a component.

选择后，指定是否应将零长距应转换为点特征（即，autocad_point).

If the feature becomes a point, it will still retain all the attributes it had while it was an arc.

Usual AutoCAD-to-AutoCAD translation setting:Never selected

指定读者是否会忽略冷冻层上的所有功能。

如果选择，则不会从输入数据集读取位于冷冻层上的功能。

If not selected, the features are read from the frozen layer.

如果您有ESRI世界文件（*.WLD），请选择此参数，该文件在确定数据集中的功能时使用FME使用。

FME will search the folder of the dataset for a file with the same name as your dataset but with a.wld扩大。如果它找不到具有该名称的文件，则将查找文件esri_cad.wldwithin the dataset folder. If either of those files exists, FME will use the information in the files to translate the coordinates of the features in the dataset to their new geospatial coordinates.

如果找不到文件，则使用数据集中的坐标信息继续进行翻译，而无需执行任何其他转换。

确定FME是否会尝试读取代理实体的图形表示，这些代理实体是某些不支持对象的占位符。默认情况下，FME将读取代理图形。

Determines whether FME will attempt to read certain AutoCAD System Variables that are stored within the drawing. By default, FME will not read Drawing System Variables.
