Tee Junction

[shehab_fekry]

I'm creating a plugin that creates pipes connecting vertical pipes to horizontal main pipe, the problem is when i create these pipes manually Revit automatically creates Tee Junction in the intersection point between these two points as shown in first picture , but when created by Revit API no Tee junction is created as shown in second picture , the fact is I think it can be done by placing a family instance and then try to split the pipe in the intersection point then connect each connector to the tee junction, but that process is not easy as it seems, Revit does that automatically when drawn manually or when you move the location line a little bit back then return in to the same position or when you Extend/One Element , the Junction is created with the right parameters and angels

I believe that the MEP routing preferences determine which tee is used when creating the system in the UI. Can you apply the same routing preferences in the API as well?

@shehab_fekry ：in code , need to break the pipe to two pipe and use newteefitting to connect three point.
