finestra errore - revit 2016

[vale79]

Hello everyone
I am trying to draw objects in revit 2016.

when I load the file in the project comes out this error window but I don't understand what it means.
Is there a decoding table of these codes? How do I know what I'm wrong?

I first created the walls, then the cross, then the development of the pipe; for the pipe I made 2 extrusions on path, on two different planes, once I loaded everything in the project and I saw that it worked I joined the two paths.

to make the top curve it seems to have used the same method: chosen the plan, designed, bound, extruded on path... but that the pieces are united or not when I try to load it in the project gives me that error window.

What's wrong?
Thank you very much
That's right.

try to do this otherwise. in the vex of doing it as a group of small parts, try to do it as one thing, using the solid of "sweep", with the percurse for "pick path". first, you make an auxiliary solid, like a box, which is used to define different work plans to create the percurse with model lines. After that, we do the "sweep". This box must remain in the family, but invisible.

Thank you very much @alfredo medina !
At the moment I solved, there was something wrong with the design of the curve, I think of the constraints, but I will certainly try this method because of pieces to draw I have several, surely it will be very useful.
Thanks again
