Here are extension methods for the ETAS INCA .NET API that provide a GetItemInFolder() method for the Asap2Project and Asap2ProjectFolder classes. It behaves the same way as DataBase.GetItemInFolder().

hello, Do you have the Tool API document about ETAS INCA? and if I want to Python to develop the script to control Inca, can you give me some advice?

Hello, how to get the namespace de.etas.cebra.toolAPI.Common?

Is there any reference code to automate INCA using python..

I've received a few e-mails and comments on this gist over the past few years. Since ETAS continually updates their documentation and API, I would recommend reaching out to your local regional office to get a copy of the latest API documentation. (This documentation is available free of charge to all licensed INCA users). At the time of this writing, you can find that contact info here: https://www.etas.com/en/contact.php
