Extrude-SetPath = strange result

 From:  artisanicview

I'm working on a project in Rhino who involves the use of some extruded shapes, but I can't find any solution to do what I need.
I thought to try MoI and see if I can get better results but seems that I get the same strange results like in Rhino.

My intention is to replicate the "Follow-me" command from Sketchup in MoI. For this I used the Extrude command, I selected the shape I want to extrude, after that I choose "Set path" and selected the path along which I need the extruded profile to be applied. The result unfortunately it is not what I'm expecting, a nice profile following the path in exterior, but instead the profile seems to be distorted and in front of the profile is missing by entirely. What I am doing wrong?
