Thicken problem

Hello

I´m trying to do a thicken to the loft in the image but isnt working. The error that shows is:

Help please.... 😞

it is probably the areas of high curvature indicated in your second image. If you offset a curved surface by more than the curvature, it creates a self-intersecting surface, and Fusion does not allow that. You will need to investigate the creation of this surface, and see if you can fix those wobbles in the surface. Are you able to share the model here (and also an indication of the desired thickness)? We can only help if we have your data (but no guarantees that this thicken can be fixed...)

I might be on the wrong track here but if you used a mesh section curve and created a loft directly using that curve as a profile then that is the problem. As @jeff_strater has said, if you can share the design that would be helpful.

Hello

Thank you for the help.

I will send you the file.

I can change the sketch because it was to fit the foot of the model.

Thank you

You used a number of mesh section sketches and then I assume you used the "Creat->Fit curves to mesh section" function.

Your scan is pretty rough and includes a lot of noise. My suggestion would be to set the fit tolerance to 0.5 mm or larger. The default is way too small and that's the reason every little surface "wiggle" is included in the curve.

Hello

Yes, I used the "Creat->Fit curves to mesh section" function.

I can´t rise the tolerance because I´m going to print the model ant it has to fit the feet to perfection.

I can´t change the sketch or do smooth.

Thank you

Susana

Based on 30 years of experience as an engineer I would consider that to be incorrect.
