Hi to all you Guys, I don't know what Revit want me to do in this case, This profile of wall I created to retrace the arc from a dwg line linked, seems ok, It has been all closed, nothing seems to be change but It came up with these three messages.
Unable to create extrusion.
The drawing constraints that define the highlighted element cannot be satisfied. The profile created in the prospectus is not valid.

Clinking on the warning messages: It is saying : is not possible to find the view.
Here the file attached.https://we.tl/t-TmL6aW8wrx
