Hello,
I have a great experience in arcpy/python programming (5 years) and I have always complete my task. I had developped multiple toolbox for my company...
I would like to understand your project: you would like a tool which is able to create a 3D layer (which will be a kind of mask) and to apply it according an airport situation?
Do you have more detailled explanation? I haven't seen any attached document with your request.
As I have plenty experience with python, I would be happy to discuss with you about your project and your expectations related to it.
Regards,
Seb.
