ArcGIS Pro scripting tool (6) -- repairing CAD layer data sources

Pro Yes CAD File support is obviously better than ArcMap. Although they will CAD Identify points 、 Line 、 Noodles 、 Polyhedron and notes 5 Categories: , But when we drag one of the classes to Pro In the middle of the day ,Pro Automatically display it in layers , And the color of the layer is the same as CAD Agreement .nice！

But the embarrassment is , once CAD File moved location or changed name , It's a long list of red exclamation point warnings . Experienced users may expect to repair a layer after , Other layers are automatically repaired , But it's a pity that this is not for these CAD Invalid layer .

I'll put it off again CAD Just come in ？ Maybe not , Because it's already in Pro The symbol system of some layers has been changed in , Drag again CAD You have to redo the symbol system of many layers , It's too troublesome .

For different situations , There are different solutions .

1、CAD File location changes , The file name does not change

In this case , The more convenient way is to open Catalog view - Contents tab - data source - working space , choice CAD Layer groups , Fill the new path with CAD The current location of the file , Click application , complete .

 2、CAD The file location and file name have changed

The solution is one more step than the above , It needs to be updated first CAD file name . Or consider using scripting tools to implement .

Python Script

import os
import arcpy

aprx = arcpy.mp.ArcGISProject(r"CURRENT")
m = aprx.activeMap
groupLayer = arcpy.GetParameterAsText(0)
lyrs = m.listLayers()

cad = arcpy.GetParameterAsText(1)
cad_name = os.path.basename(cad)
cad_path = os.path.dirname(cad)
cp = {'workspace_factory': 'Cad', 'connection_info': {'database': cad_path}}

for lyr in lyrs:
    longName = lyr.longName
    if longName.startswith(groupLayer) and lyr.isGroupLayer==False:

        lyrCIM = lyr.getDefinition("V2")
        dc = lyrCIM.featureTable.dataConnection

        # Update the feature dataset with the new CAD file name
        dc.featureDataset = cad_name

        # Update layer CIM
        lyr.setDefinition(lyrCIM)

        lyr.updateConnectionProperties(lyr.connectionProperties, cp)

        sym=lyr.symbology
        color=sym.renderer.symbol.color
        color['RGB'][3]=100
        sym.renderer.symbol.color=color
        lyr.symbology=sym

        arcpy.AddMessage(' Repaired  '+lyr.name)

  Model description

In addition to repair CAD Outside the data source of the layer , The scripting tool also cancels all CAD Transparency of the face symbol of the layer , It is convenient to uniformly adjust on the Appearance tab .
