I want to join ModelLines..!
The picture consists of six ModelLines... like that! only one model line!
If you are asking how to join the six model lines into one single element, I must say that I do not believe that is possible.
However, the first thing you should always do to research how to solve a Revit API programming task is to find out how to address the issue optimally and using best practices manually through the end user interface.
Can you join those six lines manually in the user interface to one single element?
If so, use RevitLookup to explore how that element is represented in the Revit database.
If not, it is probably not possible programmatically through the API either.
