Thicken not possible in smaller thickness

[Anonymous]

Hello,

I'm wondering why I can't go any lower than 2.6mm (or so) when I try to thicken a loft I created in patch environment.

I got the error "Error: The operation failed. Try adjusting the values or changing the input geometry."

My model is there : http://a360.co/2I6RDhf

The original component is named "Coque", I cloned it into some other component to test 3d printing at different thickness.

I tried at 2.8mm and I think it's a bit too bold, so I'd like to try at 2.4 or even 2.0.

I'm not necessary seeking for a solution (I'd love to but, 2.8 can work) but I'd like to understand why I get this error so I can explain it to my viewers.

Thank you very much !

Hi @Anonymous, 

Thank you for your posting! 

When I did an offset 2.0mm and 2.4mm I can see the distorted surface. 

I tried to move the point in Loft, it only works in 2.0 mm, it failed in 2.4mm. Here's the step. 

I looked into your sketches and I think this part would make some issue.

Why don't you create the surface separately? 

Although you did create the body, the quality doesn't look good. Do you have to keep the small line? 

Please share any your thought. 

Many thanks, 

Ahreum.

Thank you so much, you are totally right.

I don't remember clearly why I put a distance of 2mm between these two points. As far as I can remember, the loft command argued something if I designed my sketch using the same point, but well, it looks like the problem where somewhere else as it works like that.

Loft command can be a little touchy and its error message are not always super clear to rookies like me 🙂

Anyway, thank you for your time and this solution.

After some test print I think that I'll stick to the 2.8mm, probably that having some infill make the part very stronger, but I'm very happy to see the zebra stripe is way clearer like that.
