I see what you mean now Doug. Try making all that.....with one surface instead of 6. You should be able to reference parent planes as a normal reference at every curve.
HATE not being able to play with things like this..... BUT, hopefully that will get solved soon.
Now that I've played with this method, how did you determine the diagonal section parameters.
That 3 way union radial distance isn't defined unless you start with a sphere.
I already built is as an N-Sided patch (see my original response above Re: Does anybody know how to create this model ?), I was responding to the Steven's suggestion (Re: Does anybody know how to create this model ?) to create all the curves and connect with boundary blends. I couldn't get it to work because the tangency couldn't be solved.
Using boundary blends, I'm not sure you can do it in fewer than 6 because of the 4 curve requirement, or am I missing something?
I got the boundary blend to build and to be tangent, but it's not as nice as the N-Sided patch. I think if I played with it some more, I could make it better, but I've spent too much time on it already. The RH side & LH side in the image were built differently and the LH side came out better. I suspect duplicating that method would yield better results.
It's attached below.
The N-Sided surface is very nice when defining the periphery as one surface.
That section through the diagonal can be defined in many different ways but in general, it becomes a very critical junction - IF - you're going to try to define it.
I am not sure if Steve did define this and if so, using what type of feature.
Technically, I would try to specify the spherical radius for the 8 "points" of intersection. However, it is very easy to define a really crummy surface regardless of tangency or continuity.
Looks a lot better! Without access to a system, I'm guessing. I'd try putting all 6 curves in direction 1, then use a normal constraint for the edges....if it will let you. This looks interesting, it's frustrating for me that I can;t dig into it.....
N-sided patches work great for this stuff though!
Hopefully that will change soon......
