Shell failure in Create Shell Features tutorial

I have been following the Get Started with Creo Parametric Modeling playlist to learn Creo as a SolidWorks user. The playlist was straightforward until I got to the Create Shell Features tutorial. Setting the shell thickness to 3.50 causes the feature to fail, and even setting it to 1.50 results in thin geometry being created.

While I don't believe I've made an error, it's possible I overlooked something when going through the tutorials. I've attached the part file to this post (it's a Creo Versioned File, which cannot be uploaded directly to this forum).

 

Version: Creo Parametric 8.0.4 student edition, Creo Parametric 10.0.0 student edition

NOt being able to open a student version file, I would guess that your revolve did not fully intersect with the tank, leaving a small notch (see below).  Increase the revolve angle or decrease the diameter.

    Hi,

    in my test model the problem is related to "red circle area".

      Thank you @kdirth and @MartinHanak for the quick replies. The issue was indeed the revolve angle being big enough, so it is curious that 210 degrees worked in the official PTC tutorial but not with the student versions of Creo. I increased the revolve angle to 300 degrees, and while I couldn't increase the shell thickness to 4.0 or above like Martin could, I was able to complete the rest of the playlist with some other errors.

       

      Having someone from PTC go through this playlist would improve Creo's new user onboarding experience. Some instructions cannot be followed with the available student editions (at the very least), and fixing these would make transitioning from other CAD programs easier and more attractive.

      I had the same issue as you did with the instructions.  But, being an experienced user, I knew what to look at.  I clicked the thumbs down at the top of the page and left a comment on the inaccuracy of the instructions.
