The field calculator will only apply to the selected records. If you are at all concerned, run your field calculations in an edit session, where you have the option to "undo". ... View more

The criteria for symbolization returns a value in the source layer, so it displays something. The criteria for symbolizing the second layer does not return a value, so nothing displays. Think of  your symbology criteria as a query, and verify that the "query" returns a true value for display. ... View more

I assume you have a basic level and not a standard or advanced ArcMap license, as they have tools to do this. A basic level license does not have access to those tools. There is a third party tool called "ETGeowizards" that will do this in their free version. It is a very useful tool, providing access to functionality that is unavailable within ArcMap with a basic level license. - Jim ... View more

I see. This requires coding to work with the shapefile, or conversion of coordinates or attribute table to a text file for application of geometry formulas SIN and COS in a spreadsheet or database. Sorry I can't provide a better solution, James_Blythe   ... View more

James_Blythe   It seems like COGO tools may provide what you need. However, is the shift distance and azimuth actually a direction / distance that traces a path using the points as a connected line, or are they completely unique, with no real relation to each other in their locations, and not a distance and bearing? A sample would be useful if that is something that you can provide. Regards ... View more

As painful as it might be, the first item in the list is to uninstall and re-install the software. Sorry. ... View more

Yes, it should not be an issue. NOTE: You should create a new field and calculate it based off of the original, so if there are any problems, you still have access to the original source field and values. ... View more

Ibuava, The result of this operation will be a string. Numeric values do not have "dots" in them. Within python, as a string, you can use a simple string slice and append function, such as: oldNum = str(1234567890) newNum = oldNum[:2] + "." + oldNum[2:4] + "." + oldNum[4:7] +"." + oldNum[7:] newNum '12.34.567.890' This assumes the oldNum is 10 characters in each entry. If it is not always10 characters, work from the end of the string value to the front, instead. If you are trying to do something else, please provide more information so you can get a targeted response to your question. Regards, Jim   ... View more

KenBuja - excellent call. I agree with you. ... View more

SoratoMarques,  This is a standard function that has an arcpy sample as part of the help about this function. Do you have the spatial analyst or 3D analyst extension? One of these is necessary for access to the tool. If none of this helps you solve this issue, what is the error or problem with the methodology? Regards,  - Jim ... View more

A little information? Are you exporting or printing to PDF? What size is your layout, 8.5x11 11x17 etc What are your settings under the export options in the General and Format tabs? ... View more

This sounds exactly like a projection issue, CoreyMacIssac1. Try adding your polygon shapefile to a new, empty map, and see how it displays. If it appears as expected, this verifies my assumption that it is projection related. If this does not provide the information you need, post your shapefile, and perhaps I or someone else can provide a better response. Regards ... View more

This is a matter of personal preference. Personally, I would place it in the legend as "AP (Airport)" If the resulting legend becomes too big, I would add a notes text item such as "Notes: AP = Airport" and any other abbreviations you need to explain. Regards ... View more
