I started experiencing the same poor performance with my 10.5.1 installation. I don't recall at what point it became that way but today I un-installed 10.5.1 and installed 10.6.1 Unfortunately this hasn't helped in the slightest. I have a very powerful laptop and have done everything that you tried as well and still it takes close to 2 minutes on the "Initializing Application" part. I am out of ideas. This is annoying as I use ArcMap on a daily basis. Brian did you ever resolve your performance issues? ... View more

I had a feeling that you were going to say that. I wanted to avoid creating disjointed datasets to achieve the labelling that I require. ... View more

Hi Xander, Since you were so helpful with this thread, maybe you could suggest whether or not the following would be possible without creating additional datasets to accomplish what I need: Let's say I have a multipart polygon feature that has 4 parts to it. I would like a way to label each individual part with its part number (1 to 4) and its corresponding area. Is there any way of accomplishing this without making interim/temporary datasets? ...

Hi Xander, Thank you for your reply to my thread. I am running this from the Python window within my ArcMap MXD so I have taken some guidelines from your code posted above. This is what it looks like now and it is working 100% as I need it to: import arcpy ... from arcpy import env ... env.workspace = 'some.gdb' ... fc = 'someFC' ... fld_areatext = 'AREA_TEXT' ... flds = ('SHAPE@', fld_areatext) ... edit = arcpy.da.Editor(env.workspace) ... edit.startEditing(False, True) ... edit.startOperation() ... with arcpy.da.UpdateCursor(fc, flds) as curs: ...     for row in curs: ...         polygon = row[0] ...         lst_area = [] ...         for part in polygon: ...             poly = arcpy.Polygon(part) ...             lst_area.append(round(poly.area,2)) ...         poly_text = ';'.join(lst_area) ...         row[1] = poly_text ...         curs.updateRow(row) ... edit.stopOperation() ... edit.stopEditing(True) Many thanks for your assistance. Much appreciated! ... View more

I know I can use the Reshape Polygon tool but I'm looking for something that will speed the process up significantly as I have a lot of these "chamfer" type triangles to add at these road intersections. In the interim I have decided to use a point layer as a construction layer and have used the "Point at end of line" construction tool to create the points at my specified distances down each polygon edge away from the apex point. I then just edit the vertices of the polygon to include my constructed points. I was ideally looking for a way that I could create a simple tool to automate my series of clicks and typing distances in. ... View more

Hi Chris, I have been in GIS since 1997 and taught myself how to program in Delphi. It is definitely not the most popular of development platforms and there's also limited help available for it regarding any of the ESRI active-x controls. Despite this I developed a customised ArcReader application for our company that has specific search and export dialogs. Updating of the data is only done on a quarterly basis and the data is just copied over to the standalone users and to a network share for others that don't go out in the field. I could assist you by customising my app to your specifications but it would mean communicating over email or Skype to see what your requirements are. I am based in South Africa. Cheers, Alan ...

I developed an application using the ReaderControl but using Delphi not Visual Basic. I seem to remember that I also couldn't implement my own version of the MarkUp tool. ... View more

If you haven't managed to figure it out by just looking at the magnitude of the values, then as suggested by the others go back to the client and ask what system these values relate to. ... View more

It appears this is a bug, NIM097273. Hi Jake, Many thanks for your efforts in helping to resolve this issue. I'm happy to hear that it's a bug and not just something I was doing wrong. Regards, Alan ... View more

Hi Alan, You can place the code within a function and execute it using the field calculator.  Ex: def update():   fc = r"C:\temp\python\test.gdb\Vehicle"   pnt = arcpy.Point()   rows = arcpy.UpdateCursor(fc)   for row in rows:     pnt.X = row.GPS_X     pnt.Y = row.GPS_Y     row.shape = pnt     rows.updateRow(row)   del row, rows Be sure that you have 'Python' checked at the top of the field calculator, and you will want to specify 'update()' under the Pre-logic script code dialog.  Ex: [ATTACH=CONFIG]33269[/ATTACH] Hi Jake, Many thanks for the response. Can you explain to me why the following python code doesn't work? I have joined my GPS shapefile to my point feature class (Point Z) based on a unique ID field present in both datasets. In the attribute window of my feature class I have 2 features selected (just as a test). I right-click on the SHAPE field and choose Field Calculator. I change my parser to Python and tick Show Codeblock. Under the Pre-Logic Script Code, I have the following: def SetToGPS( shape,newx,newy 😞   point = shape.getPart(0)   point.X = newx   point.Y = newy   return point And under the bottom box I have: SetToGPS( !mobile.SDE.WaterDevices.SHAPE!, !Gledhow_Devices_Surveyed_By_Andrew2.ArcMapX!, !Gledhow_Devices_Surveyed_By_Andrew2.ArcMapY! ) This results in a syntax error. In the code that you have suggested, the GPS_X and GPS_Y fields are presumed to be immediate fields in the feature class. In my case they are joined fields, so how do i reference them? Regards, Alan Edited: The following worked for me. I had to add immediate fields to the feature class to hold the new X & Y values (GPS_X & GPS_Y) and while the join was still present, calculate these fields with the values from my joined fields. I then removed the join from my feature class and the code below then ran without a problem: CODE: def Update(newx, newy):   pnt = arcpy.Point()   pnt.X = newx   pnt.Y = newy   return pnt SHAPE = Update( !GPS_X!, !GPS_Y!) Jake, maybe you could explain why I couldn't do this while there was still a join present and why it only took immediate fields as input into the function? ... View more

Hi Jake, I need to do exactly what Dillon was wanting to do but not as a standalone Python script. What code would need to be used to perform the same calculation from within the Field Calculator dialog (as depicted in his original attached screenshot)? Any help or suggestions appreciated.
