Geometry is broken after running Python script

Anonymous User — Sat, 22 May 2021 13:14:32 GMT

Hi all

I'm using ArcGIS Desktop10.6. I created Python script to process data, but I can't see any polygon after running the script. There is no error during the process and updated table is attached properly.

I run 'Check Geometry' tool and it returns "bad dataset extent".

I run 'Add Spatial Index' tool, but Error999999 shows up.

Can you help me what is wrong with my script?

arcpy.AddField_management(OutFC, "FBreak", 'TEXT', "", "", 20, "", "NULLABLE")

with arcpy.da.UpdateCursor(OutFC, ["SHAPE@","FBreak"]) as cursor:
for row in cursor:
Buff20 = arcpy.Buffer_analysis(row[0], arcpy.Geometry(), "20 meters")
CFBreak = OutPut + '\\CFBreak'
arcpy.Clip_analysis(FB, Buff20, CFBreak)
Count = arcpy.GetCount_management(CFBreak)
if Count == 0:
row[1] = "None"
elif Count >= 1:
row[1] = "Exist"
else:
pass
arcpy.Delete_management(CFBreak)
cursor.updateRow(row)

Buffer and clip Analysis need to be using featureclasses

Buffer (Analysis)—ArcGIS Pro | Documentation

If you want to use cursors, use the equivalent functions in the arcpy class structure

I changed Buffer part as:

Buff20 = OutPut + '\\Buff20'
arcpy.Buffer_analysis(row[0], Buff20, "20 meters", "", "", "NONE", "", "")

However, result is same. I can't see polygon..

Is there any other suggestion?

As I suggested.. if you are going to use cursors and work with geometry directly, use the geometry class in arcpy. For example, see the Polygon class, buffer method

Thanks Dan

I changed Buffer part as below, then I can see polygon and updated table!!

Buff20 = row[0].buffer(20)
