Trouble getting smooth surface/edge with SubD

Hello

Just getting to know SubD. I have used Rhino since the dawn of the software and I thought it’s time to get to know SubD tools as well. I have some odd weird pump which I don’t have enough controll. Not quite understanding why some edges are smooth and others are not.

Greetings from snowy Helsinki,
Totti

You have two stray vertices along the middle edge. The pinch will go away once you delete them.

I would also adjust your topology in the front to get rid of the two triangles.

Thank you for your advice. Much appreciated. Being so novice with SubD any change you could chare your edit (file).I feel like I have long way to go with new SubD tools…

Since your just getting into SubD id look into topics like edge flow, topology and using support loops to create sharp details instead of using crease.
https://www.youtube.com/@OnMars3D this is a good channel to learn from its not in rhino but all the ideas still apply.

Thank you Tommy, I’ll look into it and thank you so much for the file edit!
