This is my work laptop, don't have a home machine. It is WIndows 10 Pro that is always kept up-to-date with Windows updates.

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?

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.

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!

Good day, I have a polygon feature class in a file geodatabase. There are a few multipart polygons in the dataset. I have added 2 fields to the dataset to store the number of parts (numeric) and one to store a list of the individual part areas (string). I have populated the field with the number of parts using one of the functions in the EasyCalculate Add-In. However, I require assistance with populating my string field with a delimited list of the individual part areas for any multipart polygons in the dataset. So for example, if a polygon has 4 parts to it, the value for the string field that I want calculated should look like this -> "541.00;236.54;147.85;391.25" being the individual areas of the parts of the multipart polygon. I found some python code that iterated through the polygons and their respective parts and printed the results to the python window. However I need to concatenate the areas into a delimited string and write the string to the feature. I cannot seem to get that part of the code correct. Here is the link to the thread on another website for accessing the part areas python 2.7 - Getting area of multipart features using SearchCursor() of ArcPy? - Geographic Information Systems Stack Ex… Please could someone help with the code to write the individual areas in the string back to the feature? TIA

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.

I have a road layout and at the road intersections I need to create what are termed "splays" in the Survey world. This is usually done by choosing the apex point and then creating a vertex a defined distance down each polygon edge running away from the apex point. The triangle is then created by joining the two new vertices with the apex vertex. I then need to merge this new triangular polygon with the adjoining polygon. See below: And the end result being: Is there a way to create a tool in ArcMap to achieve the above easily? Currently the method I am using is very cumbersome. Or has anyone already created such a tool? Thanks in advance!

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.
