PIN Number Tool

[jgarrido]

Good morning everyone,

I'm kinda new to Python but have been able to create a lot of tasks that allow me to automate certain functions that we used to do manually. Here is my current dilemma. I have been tasked to create a PIN generator that uses the centroid of the parcel to create the PIN. I have created that and it is working beautifully. The problem is I need it to run in ArcMap as a button and ONLY on selected parcels - the current code runs it on all parcels.

How can I modify this code to only run on selected parcels within the MXD I'm using and also use a button created through the Add-In manager.

Thank you in advance.

Code:

# ArcGIS 10.4.1 script that creates Parcel ID Numbers (PIN)
# and PIN4 numbers for parcels. It uses the centroid of the
# parcel to calculate the PIN.
