ArcMap

Add CAD Fields

Summary

Adds several reserved CAD fields in one step. Fields created by this tool are used by the Export To CAD tool to generate CAD entities with specific properties. After executing this tool, you must calculate or type the appropriate field values.

Usage

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

  • You can add fields to a table other than a feature class and join the tables using a field that exists in both tables. Using a lookup table can be an efficient way to standardize and reuse common CAD property values.

  • 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

arcpy.conversion.AddCADFields(input_table, Entities, {LayerProps}, {TextProps}, {DocProps}, {XDataProps})
ParameterExplanationData Type
input_table

Input table, feature class, or shapefile that will have the CAD-specific fields added to it

Code sample

AddCADFields example (stand-alone script)

Add reserved CAD fields to attribute table for use with ExportToCAD tool

# Import system modules
import arcpy

# Set workspace
arcpy.env.workspace = "C:/data"

# Set local variables
input_table = "C:/data/EditorTutorial.gdb/StudyArea/Buildings"

# Process: Add CAD Fields
arcpy.AddCADFields_conversion(input_table, "ADD_ENTITY_PROPERTIES", 
                              "ADD_LAYER_PROPERTIES", "NO_TEXT_PROPERTIES",
                              "NO_DOCUMENT_PROPERTIES", "NO_XDATA_PROPERTIES")
