Creating cross sections
I am trying to replicate this drawing of a solidworks model from their model mania. (https://blogs.solidworks.com/tech/wp-content/uploads/sites/4/Model-Mania-2004-Phase-1.jpg)
I am having trouble recreating section B-B in my own drawing, the closest I have come to this is below.

I have tried using zones and dabbled in full aligned/unfold cross sections but I am unable to figure how to do it. Help would be greatly appreciated.
I am using creo parametric 9.0 student version.
