Hi all (again!) I’d like to pick up this old thread with a similar issue, as the geometry is somewhat similar. We found several great solutions last time, and also tips and tricks about how to simplify things.
This time, I thought it would be much easier as the geometry is less complex. But I can’t really figure out how to solve it the best way, as I end up in similar problem no matter how I do it.
So, firstly - the visual result I’m after is this: The sharp edge (blue) shall disappear smoothly as it merges into the blended surface (red)
The file looks like this:
[Yellow] is where the blended (curvature) surface shall go up to, and the [red] is the curvatue used for splitting the “flat” surface. Like this:
Now, my problem begins. As shown above I have created the first blended surface (grey) and also the 2nd one to the right. The flat bottom goes out to infinity, a sharp edge, to bind the grey surfaces together. My issue is, that no matter how I try to build this surface, I end up in, if I exaggerate this image, in a situation where they don’t match up:
I do understand, since the bottom surface goes all the way, that mathematically the blend tool tries to keep curvature all the way. Even though the surface is almost invisible. And therefore create a surface like this.
But when I try to build it manually instead, with a set of support curves along the way, and skip curvature at the end, I end up in flimsy surfaces with creases and bumps. Am I missing something obvious here? How can I make this sharp edge to fade out nicely?
