New User Question - Shaper Pipe Operation

Hello!

Just started learning Salome. I’ve been following the Shaper tutorials by Cyprien Rosu (on Youtube). I’m not able to replicate his results on the 2nd tutorial where he creates a pipe part.

My pipe operation always ends with a ‘stunted’ elbow with the extrusion not tracing the selected wire. The wire (seen in a dark line) moves towards the back of the elbow (The wire consist of 2 straight lines and one arc, with tangent, radius, length constraints, coincident constraint to origin)

As you can see in wireframe below, the pipe center does not follow the wire path.

Can anyone advise me where I’ve done wrong?

Thank you! CJ
