Hello, I've got the following issue to address: I process a bunch of shapefiles with a certain name stored in a folder. I use the %name% variable to name the outputs of geoprocessing operations. Now, I want to use an SQL statement for a Selection (Select Tool). I don't now the exact fieldname, because the field is produced during a geoprocessing task executed before (Identity). The name is something like "FID_" +[shapefilename]+ [s+further characters], but not exactly known. So I'd like to make a query such as: "FID"+%name% + "s*" > -1 . My thought is to pass a variable containing the expression needed for the Select Tool. So far it is possible to pass a string variable such as "FID_%name%" , but the s* Wildcard is not accepted as SQL syntax. Any clues? Tank you very much for your help! Kathrin ... View more

I iterate through a list of shapefiles and do some geoprocessing chains and field calculations for each of the input shapes (works fine). The result is a dbf for each of the input shapefiles. Now I'd like to write the name of the input shapes into a field in the output dbf and then merge the dbfs. Merging works also fine. The naming process worked fine using ArcGIS 10 or 10.1, but fails using ArcGIS 10.2 and Python 2.7.3. Some snippets: #Blabla Environment + Import (...) #List FCs name = [] x = 0 fcList = arcpy.ListFeatureClasses() for fc in fcList:     print fc     name.insert(x, fc.split(".")[0])     x += 1 #Blabla Geoprocessing (...) #Write Name into output dbf and merge x=0 for fc in fcList:         arcpy.AddField_management(input ,"NAME", "TEXT")         arcpy.CalculateField_management(input ,"NAME", "name ", "PYTHON")         x += 1   out = outws + "Merge" + ".dbf" result = arcpy.Merge_management (input, out) Printing x, the input and name returns the right values for x and the file names (e.g. B, C, D, E, F). But only the first name is written into the table, e.g.: FID------BLA----NAME 0 --------    .    ------B 1 --------    .    ------B 2 --------    .    ------B 3 --------    .    ------B 4 --------    .    ------B Any idea? By the way, I get now error message, but the info "returned exit code 0". Thanks Kathrin ... View more

Hello ArcGIS Community, my intention is to create polygon features in the form of a compass rose. I use the bearing distance to line tool which works fine, creating the lines in the designated angle and distance from the center point of the compass rose. But now I need polygons. I tried to use Feature to Polygon for the compass rose line FC only and also for a FC containing a merge of the compass rose lines and a buffer of the center point, but the result is always a circle not containing the angular divisions. So how can I make polygon features out of my compass rose lines? Thank you Kathrin ... View more

Hello, the enclose multipatch tool unfortunately yields bad results. I have a multipatch FC created from an extrusion between two TIN surfaces for the area of building footprints. The Is Closed tool shows that a lot of Multipatch Features are not properly closed. Now I used the Enclose Tool to close these polygons, but this results in most shapes being distorted or looking damaged, some are also missing. Furtheron, how does the grid parameter affect the results? I often get the error message "use larger grid size", but using a larger grid size, ArcScene crashes. Using a grid size of 0.4 was the only handable value, but results in the mentioned distorted shapes. Any idea how I can close my multipatches and continue calculating surface area and volume? Thanks, Kathrin ... View more

Hi there, I used my old pretty simple rule file for building extrusion based on an attribute field in a shapefile (called "height", field type Double), but the rule does not work anymore in CE 2012. # inizialize attrs attr height = 0 # please note : If the StartRule annotation is set, CityEngine automatically checks for Object Attibutes # coming from GIS Data. If there exists one with the specific name, CE will point to it. @StartRule Lot --> extrude(world.y, height) After generating, the building footprints are black, the shapes disappeared and nothing is extruded into the 3rd dimension (see attachment). I have chosen "object attribute with name 'height'" in the Attribute Connection Editor. ... View more
