Help to build a transition surface to a hole

Rhino

Hello

I (somehow) followed this tutorial.

As an exercice I’d like to go a bit further by adding a nicer transition around the hole on the knife.
FilletEdge or BlendEdge fail, no surprise here.

Before going on the main model I want to sketch the method on a simplified version, trying to blend between planar surfaces and a planar curve.

And I’m stuck filling those holes with G1 (already acknowledged G2 is out of my skills/patience for now).
It’s a 6-sided patch and no matter how I cut it I obtain pointy surfaces or contradictory tangent directions.

SubD gives the overall look of what I’m after…

Any advice would be great. Thanks.

I would just wrap a fillet around the hole.

Hi,

Thanks but this microscopic fillet is not really what I’m looking for…

Yes it works and smoothens the edge, but accepting this as a solution really is looking away from a more generic problem that is getting better at transition surfaces.
