I am making a python code for Arcgis9.3. In this code I have an input feature and I create a Output feature. I want that the output feature is the same geometry type as the input feature. At the moment my code to create the output feature is :

gp.CreateFeatureclass("C:/Users/Desktop/Test/", NameOutFC, "POLYLINE")

But I would like to get the input feature geometry type and use it to create my output feature :

gp.CreateFeatureclass("C:/Users/Desktop/Test/", NameOutFC, GeometryLikeInput)

I found the code with ArcPy :

desc = arcpy.Describe('C:/shapefile.shp')
geometryType = desc.shapeType

if geometryType == 'polygon':
print 'Polygon'
elif geometryType == 'point'

But I can't use it with arcgis9.3.

Thanks for your help

You can use the Geometry object which is available even in 9.3.

enter image description here

The .pdf file for Geoprocessor model in 9.3

The code sample:

rows = gp.SearchCursor("D:/St_Johns/data.gdb/roads")
row = rows.Next()
while row:
    print row.Type

Alternative way is to use Describe method where you could use ShapeType:

import arcgisscripting
gp = arcgisscripting.create(9.3)
gp.workspace = r"C:\Program Files (x86)\ArcGIS\Reference Systems"
fc = r"C:\Program Files (x86)\ArcGIS\Reference Systems\utm.shp"
dsc = gp.describe(fc)
print "ShapeType: \n" + str(dsc.ShapeType)

Which gives you Polygon

Yes but in this case i have to chexk all the feature in my shapefile and the return geometry type is the geometry type of each feature. So i am looking for a code which return the geometry of the shapefile directly without reading each row and retrun each feature geometry. –  Panvjim0 Apr 30 at 9:32

Then just add a counter in the code and use the while counter < 2 in the code. Shapefile can store only one type of geometry, so you are done when you figure out the geometry type of the first feature. –  Alex Tereshenkov Apr 30 at 9:39
    
@Panvjim0, I've updated my answer to include a cleaner way to access the shape type of a feature class. –  Alex Tereshenkov Apr 30 at 11:58
