Hello,

to reduce notch stresses in corners i would like to add tangent curved fillets (see picture). (Claus Mattheck http://bibliothek.fzk.de/zb/berichte/Mattheck-Poster-050901.pdf)

At the moment i have to construct a tangent curve with the "Equation Driven Curve" tool, but this is not very flexible for parametric designs.

**How do alternatives approaches look like to use tangent curved fillets?**

Best Regards

F.R.,

I would be inclined to use a Spline if you want to add the shape in the sketch and a Fill or Boundary Surface if you want to add it in the solid or surface model. I'm not sure how well they will behave if your change your model parameters a lot.
