Add CAD Fields (Conversion)

Summary

Adds reserved CAD fields recognized by the Export To CAD tool. These fields are used to specify the CAD properties of the exported featuresAfter executing this tool, you must calculate or enter the appropriate field values.

Usage

• All input feature classes and/or feature layers are valid inputs to this tool.

• Adding CAD fields to a feature class intended for export and calculating values into those fields is a quick way to specify the various CAD properties for export.

• Adding CAD fields to a table other than a feature class is a useful way to create a lookup table of standard CAD property values. By joining this lookup table to a feature class based on some key field existing in both tables, a CAD standard can be defined and reused. Such a table can specify how feature class data is represented in a CAD drawing.

• If the input is a table view or a feature layer with a joined table, the fields are only added to the base table (not to the joined table).

Syntax

AddCADFields_conversion (input_table, Entities, {LayerProps}, {TextProps}, {DocProps}, {XDataProps})

Parameter	Explanation	Data Type
input_table	Input table, feature class, or shapefile that will have the CAD-specific fields added to it	Table View
Entities	Adds the list of CAD-specific Entity property fields to the input table ADD_ENTITY_PROPERTIES —Adds the list of CAD-specific Entity property fields to the input table NO_ENTITY_PROPERTIES —Does not add the list of CAD-specific Entity property fields to the input table	Boolean
LayerProps (Optional)	Adds the list of CAD-specific Layer property fields to the input table ADD_LAYER_PROPERTIES —Adds the list of CAD-specific Layer property fields to the input table NO_LAYER_PROPERTIES —Does not add the list of CAD-specific Layer property fields to the input table	Boolean
TextProps (Optional)	Adds the list of CAD-specific Text property fields to the input table ADD_TEXT_PROPERTIES —Adds the list of CAD-specific Text property fields to the input table NO_TEXT_PROPERTIES —Does not add the list of CAD-specific Text property fields to the input table	Boolean
DocProps (Optional)	Adds the list of CAD-specific Document property fields to the input table ADD_DOCUMENT_PROPERTIES —Adds the list of CAD-specific Document property fields to the input table NO_DOCUMENT_PROPERTIES —Does not add the list of CAD-specific Document property fields to the input table	Boolean
XDataProps (Optional)	Adds the list of CAD-specific XData property fields to the input table ADD_XDATA_PROPERTIES —Adds the list of CAD-specific XData property fields to the input table NO_XDATA_PROPERTIES —Does not add the list of CAD-specific XData property fields to the input table	Boolean
