The Session class in the SpaceClaim API provided a way to start a SpaceClaim session and load an AddIn DLL.

Is there anything like that (currently or planned) for Discovery?

Thank you.

Hello Blair, 

When you say start a SpaceClaim session through the Session class are you referring to a .NetRemoting call? Or something else?  

I will check what the session class does but in general the way to start Discovery is to provide a path to the executable and a manifest file to load add-ins. There is no need of any class to achieve this. 

Regards,

Devendra

Devendra,

Below is the C++ code that we use to launch SpaceClaim and then load our Addin.
