Slicing. Shell settings problem. Non continuous shell. Weak union

[fundamental4 0]

hello all,

my first post here and newby using Cura.
 

Please find attached photo.

 

I sliced a part, and wings (paddles...) are "left" as a different CAD body. Cura creates a weak point. 

 

Then I compare with Repetier-Slic3r and it was fine (blue model).

Both have 3 layer shell.

 

I'd prefer use Cura.

 

How can I solve this issue?

 

Thank you.

Can you attach the model for others to test slice?

Hi all,

I realize now, and I found the problem. It was my fault, beginner design mistake. It is amended now.
The Sketch and Extrude features were not correct. What Cura found and did was ok.

Attached photos.

 

Thank you for your reply.
