Profile Rib feature not generating beyond a narrow width

[KJ_11561832]

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 🙂

What's the OD of the boss?

[KJ_11561832]

52mm OD, 32mm ID

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

Sorry that was my bad. I extended it too far in the example image, but I meant to create a 12mm rib and it still doesn't work.

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

Thank you for the response!

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.

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.
