Extract feature classes from CAD file

RPGIS — Mon, 13 Sep 2021 14:01:55 GMT

Hi,

I am currently working on a tool that converts CAD files submitted by users and then extracts the data and processes it in such a way that we can use that data internally. I need to enable the end user to select or upload the cad dataset and select the type of feature classes that are involved. So my question is, is there a way to set up the tool validation to select all of the feature classes that are in the CAD dataset?

class ToolValidator: # Class to add custom behavior and properties to the tool and tool parameters. def __init__(self): # set self.params for use in other function self.params = arcpy.GetParameterInfo() def initializeParameters(self): # Customize parameter properties. # This gets called when the tool is opened. return def updateParameters(self): # Modify parameter values and properties. # This gets called each time a parameter is modified, before # standard validation. CAD_Dataset = self.params[2].value featureclasses = self.params[3].filter fieldname = self.params[4].valueAsText SubdivisionLayers = self.params[5].filter ParcelsLayers = self.params[6].filter RoadLayers = self.params[7].filter if CAD_Dataset: featureclasses.list = [fc for fc in arcpy.ListFeatureClasses(CAD_Dataset)] fieldname = "Layer" fcfields = [fieldname] attributevalues = [row[0] for row in arcpy.da.SearchCursor(featureclass, fcfields)] UniqueAttributes = set(attributevalues) SubdivisionLayers.list = [str(value) for value in UniqueAttributes] ParcelsLayers.list = [str(value) for value in UniqueAttributes] RoadLayers.list = [str(value) for value in UniqueAttributes] return def updateMessages(self): # Customize messages for the parameters. # This gets called after standard validation. return # def isLicensed(self): # # set tool isLicensed. # return True

Any help on this would be greatly appreciated.
