Hi everyone, I have a question need your help...

I'm now developing an plug-in for Revit, the task for it is to export data from document.
by now it almost completed, just use generic Revit API , no specific API for MEP or Structure.
It seems OK to analysis the models in Architecture, but when it used to MEP, some questions came out.
It just can not get the geometry of Connector, although I checked all relevant documents can be found , no solution could be got.
like this:

they explained some relevant reason but not give the answer, all I want is get the triangular coordinates of the connector, so i can reproduce it.
Is it possible to just use generic Revit API to solve it? or any other feasible solution?
