Create CAD XData (转换)
摘要
Creates an attribute field called 'XDList' in the Input Table.
旧版本：This is a deprecated tool. To learn more about how this tool works click here to view archived documentation. This functionality has been replaced by the tool Export_to_CAD that now exports feature class schema, attribute values, and coordinate system information to XRecords as defined by the ESRI Mapping Specification for Drawings.
用法
-
All input feature classes and/or feature layers are valid inputs to this tool.
-
XData is only read by AutoCAD.
-
The XDList field that is created by this function is read by the tool Expor to CAD when exported to AutoCAD .
-
Extended Entity Data, though, allows you to attach up to 16K of information to each and every entity in the drawing.
-
You can also keep the XData separate from other information because it uses a uniquely registered name.
-
If your function fails with "Output exceeds field length", then include less fields in your XData string. The XData field that is added has a maximum field length of 2049 characters.

| 参数 | 说明 | 数据类型 |
In_table |
This table contains the fields used to generate an XML string of values recognized by the Export to CAD tool. This enables XData to be created on output objects, based on values of fields from the Input Table. | Table View |
Fields [Fields,...] |
The selected field values for the encoded XData. The Add Field button, which is used only in ModelBuilder, allows you to add expected field(s) so that you can complete the dialog and continue to build your model. | Field |
RegApp |
The AutoCAD extended entity data registered application name. Required by only AutoCAD to identify the XData. This application name is an identifier of the newly created XData. | String |
Output_Type |
Format of the AutoCAD XData.
| String |
