Hi everyone,

I am trying to generate a wing and I don’t know why but the loft is not creating a smooth surface (following the splines). Do you have any idea why? I’ve cheked the settings and I’ve got max resolution and anti aliasing On.

Hi,

It does follow the curve, just for performance reasons, the tessellation you see in the modelspace is lower, than what you would get from an export. Exports are more accurate.

If you zoom in very very closely, even a circle doesn’t look perfectly circular.

Thank you very much, you are right this is a big zoom in! Ok I will export and check the accuracy.

Many thanks!

I confirm it will works, I have made many many parts for aeromodelling, Also for molding parts😎
