Smooth Curvy Corners in Surfacing....... HOW ?????

Riddle me this Batman!

Several times over the duration of modelling my truck I've experienced a situation whereby I need to create a smooth transition between a very curved surface that has boundaries with rounded corners. I always end up with a little 'pinch' (my term) in the corner. Essentially, it's a flattened area that doesn't really conform to natural roundness. In this example, I've tried adding additional horizontal projected curves, additional projected vertical curves, but still I end up with some form of the same problem.

The above image utilizes just one central projected curve

This one has the addition of a vertical projected curve.

It also doesn't help applying 'Tangency to Face' to the boundaries either.

Surely there is a simple process to achieving this that I am missing. Any constructive advice greatly appreciated.

Dave.

Hi.

Try to change selection order in boundary surface as on the screenshots.

Hello Krzysztof,

That actually works very well, thank you for the tip

BUT... what it does is take away the fact that I need the new surface to also converge to a 'soft' V shape as it heads away. You'll see what I mean if you look at my original part from the top view. Any ideas?

Is this what you are after?

If yes, you can add additional curve on top plane.

And use it in Direction 1.

Thank you Krzysztof,

This achieved the result I was looking for! I still have a few slight signs of 'creases or ridges' in other areas now but they are barely noticeable. I was surprised to learn from your responses that the end result is dependant on the input selection of the boundaries or projected curves, I was never aware of this. In my inexperienced way of thinking, the selections are what they are and the outcome would be the same no matter what. Seeing now that this is not the case, I will be trying several selections for each such surface I create in the future.

Thank you so much for your time and effort, it's been very helpful!

Dave.

...looking,.. nope,.. there is no "smoothy curvy corner" surface option.

I found a button for that it was right next to the easy button.

Hey Paul,

Now this is the duck's nuts!

To be honest, I had to roll back through it a few times to be sure I comprehended why you had taken the steps you had. Once I got my head around it, I realised it's simplicity. I'm obviously still not in the right thought process when I'm doing some of my surfacing, but Rome wasn't built in a day huh?

In this example, thank you for teaching me how to fish!

Dave.
