Hi,
I am currently working on a project for creating a custom geoprocessing tool for the web. So far things are working great, the only thing is that I am trying to figure out is if there is a way where I can enable the end user to select the feature classes that reside within the CAD file. I haven't had any luck with this and so I was wondering if maybe it could be the way I am going about it but I wanted to check and see if anyone might be able to either give me some pointers or point me in the right direction. I know CAD files are tricky, especially if they are standalone, but if there is anyone who has written scripts to extract information from these kind of file please let me know.
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.
CADfile = self.params[2].value
featureclasses = [fc for fc in arcpy.ListFeatureClasses(CADfile)]
featureclass = self.params[3].filter
fcs = featureclass.list[featureclasses]
SubdivisionLayers = self.params[4].filter
ParcelsLayers = self.params[5].filter
RoadLayers = self.params[6].filter
if featureclass:
attributevalues = [row[0] for row in arcpy.da.SearchCursor(featureclass, ["Layer"])]
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
