Sweeping issue

Hi All

I'm relatively new to using Creo and have been going through a number of tutorials given to me, and have gotten stuck at something that seems fairly rudimentary and I hope I'm just missing something simple.

Whilst trying to sweep to generate the second image attached (tutorial model) I get the error message "FRAME regeneration completed with atypical feature or component status. Failed: 1"

While trying the edit the sketch I would receive the error "All the entities must be tangent". I eventually was able to generate a swept model by placing larger radius's on the problem sections.

I've had a look at both mine and the tutorials model, and I can't for the life of me figure out why theirs is able to sweep with the 90 degree bends and mine is not

I've looked through a couple other forum posts which mention changing the relative and absolute accuracy of the model but neither of those seemed to fix my issue

thank you all in advance
