We have many land class polygons to manually edit. I wish to create a button bar - in Python AddIns - with buttons to allocate the selected polygon (once edited) to the appropriate class (ie update attribute field). There would be buttons for Class 1, Class 2 etc..
so
i) edit polygon (eg cut)
ii) with polygon selected, click appropriate button (eg Class 1) to allocate polygon (attribute) to the appropriate land class
I can do this in ArcPy, but am new to AddIns. I am not able to find information on how to apply code in Addins
I'd suggest starting here What is a Python add-in?—Help | ArcGIS Desktop and study each of the online help sections related to addins. I started a fairly large project a year or so ago, and will be breathing new life into it again in the next few weeks; when I started the project, I couldn't even spell Python. Take your time and experiment as you go.
From the sounds of it, you'll need to be able to start an edit session, choose a value from a combo box for your land value and then make the change.
