Can someone surface to area boundaries line?

why there are no any connection to area boundary ?? no node nor api. wanna make revit difficult for sales?

Your question isn’t clear, but I assure you there is no desire to increase sales by holding back an API. Automation is central to the ecosystem as a whole.

Post a dataset, what you have attempted so far, and a clear description of what you are after and the community will try to help you out.
