Profile Rib feature not generating beyond a narrow width

I am trying to create a part from the solidworks model mania series. 

The part includes an S shaped rib feature.

The feature fails to generate beyond this very narrow thickness

What am I missing?\

 

I am using creo parametric educational edition

 

I have included a link to a YouTube video I uploaded showing the exact process I used to create this feature.

I'm also including a link to the model mania part drawing for reference

I am new to creo so any input helps 🙂

It is possible to build this using a profile rib to match the drawing reference. Do not include the rounds/fillets in the section for the rib. See the video for how to build it. As general rule do not include fillets/rounds in Creo sketches unless absolutely necessary to design intent.

What's the OD of the boss?

    You can't add a 60 mm rib to a 52mm boss. It doesn't know what to do with the extra 8 mm.

      It appears creo is having trouble connecting it to the boss.  Try extending the line beyond the silhouette edge.

        I tried it but it still isn't generating

        I tried the profile rib in 7.0 and 11.0 with the same results.  I would suggest using an extrude rather than the profile rib, since Creo is not able to follow the curvature of the boss.
