Unless you have multiple "Fields" layers you don't need to loop through anything. df = arcpy.mapping.ListDataFrames(mxd)[0] lyr = arcpy.mapping.ListLayers(mxd, "Fields", df)[0] df.extent = lyr.getSelectedExtent() ... View more

You are probably getting your specific issue from limiting your fds variable to "Fields" only. However, you have a few other issues as well. Primarily, these lines are very confusing. fds = arcpy.mapping.ListLayers(mxd, "Fields", df)[0] for fds in arcpy.mapping.ListLayers(fds): In the first line you assign your "Fields" layer to the fds variable. Then in the second line you create a new fds variable listing the layers in your fds variable. Try writing it a little cleaner using unique variable names. ... View more

You don't actually have to update each vertex according to the Café Python page.. http://arcpy.wordpress.com/page/2/ just update the SHAPE@XY token instead, then the whole feature moves. like : with arcpy.da.UpdateCursor(in_features, ['SHAPE@XY']) as cursor:     for row in cursor:         cursor.updateRow([[row[0][0] + (x_shift or 0), row[0][1] + (y_shift or 0)]]) Cheers, Neil That makes it much easier, good find. ...

You are using updateRow incorrectly. That takes a row object, not the row values. Also, if you are updating a line feature you need to change each vertex value, which means will will need to access the geometry object and step through each one, modify it, add it to an array, then pass it back to a polyline object to be updated in the geometry object. Here's an example. import arcpy rai = arcpy.mapping.ListLayers(mxd, "Railroads", df)[0] EWmove = float(arcpy.GetParameter(0)) NSmove = float(arcpy.GetParameter(1)) update_cursor = arcpy.da.UpdateCursor(rai, 'SHAPE@') for row in update_cursor:     array = arcpy.Array()     for part in row[0]:         for point in part:             point.X += EWmove             point.Y += NSmove             array.add(point)     new_line = arcpy.Polyline(array)     row[0] = new_line     update_cursor.updateRow(row) del update_cursor ...

& is used in VB usually, in python is has a different function that you are probably not interested in. Try this instead. def getclass(Value): if Value >= 0 and Value <= 10:   return 1 elif Value >= 11 and  Value <=20:   return 2 elif Value >= 21 and Value <= 40:   return 3 elif Value >= 41 and Value <=60:   return 4 elif Value >= 61 and Value <=100:   return 5 else:   return 6 You could also shorten it using this format. def getclass(Value): if 0 <= Value <= 10:   return 1 elif 10 < Value <= 20:   return 2 elif 20 < Value <= 30:   return 3 elif 30 < Value <= 60:   return 4 elif 60 < Value <= 100:   return 5 else:   return 6 ...

extent is not a property of a layer object. Read through the doc here to find what you are looking for. http://resources.arcgis.com/en/help/main/10.1/index.html#/Layer/00s300000008000000/ Also, you cannot modify the extent of a layer in that manner, you will need to modify the geometry. Finally, how you are calling a layer object is actually returning the list of layers. You will need to reference an index in the same manner you do with the dataframe object to reference an individual layer object. ... View more

After you get your data from your source, I think the easiest next step would be to use an insert cursor. Either directly into your SDE feature class or into a temp in memory feature class to then upload to SDE. See the last example in this help page for inserting geometry. It is a little easier than depicted since you are only inserting point geometry. http://resources.arcgis.com/en/help/main/10.1/index.html#//018w0000000t000000 ... View more

First of all, tooldataWorkspace is not a thing. Second, you need quotes around paths. Third, your path is mangled, there should be no colons after the drive letter. I assume you are looking for something like this. arcpy.env.workspace = ("C:/Temp/cab_homework_3_solution/Tooldata") ... View more

I would find it more likely your log file is the issue. Try disabling logging and running it a few times to see if you get the same slow downs. Also, are you closing the instance of python this script is running in between executions? The in_memory workspace won't clear properly until you terminate the instance it was executed in or you clear it explicitly. ... View more

What version of ArcGIS are you using? Can you post the code you are running? Search Cursors are quite light and shouldn't be creating any additional files. Are you sure it isn't some other part of your code that is causing the issue? ... View more
