hmm, what do you mean by “small rounded edges on your sweeps are no at all tangent to the upper and side surfaces everywhere” ?
How do I recognize if my fillets/round edges are not tangent?
Yes, you are most probably right. I was also thinking about making those sweeps with hard-edged section curves, blend them and then apply a filletedge.
Basically, I had a transition like that in mind, although in this picture it is a ring:
Thank you for that “cleaner” file, but to be honest I do not get any wiser as to what methods or commands you have used just by looking at your model.
And I can not follow your steps just as easily as I could if this were 3ds max + modifier stack.
I suppose you exploded the polysurface, trimmed the y-branch and did a couple of blendcrv commands and the patched or joined it? yes or no? Am I close?
Could you also please break down or at least give some hints on how you modelled this 2nd transition:
It looks nice as well and I would be also interested in that technique.
As to the second transition, the x-intersection, this (your file) is exactly what I had in mind, but again I am just vaguely guessing how you might have done it.
Did you explode the thicker-arm-polysurface, trimmed it with the thinner arm or a copy thereof and then blended the edges?
I am also somewhat confused about “Stratosfear has reworked your design much more extensively- pay attention to his approach”
Is a Rhino-Pro able to recognize the modelling-technique by merely looking at the isocurves of the transition? If so, then I am really sitting in the back of the class…
I am a beginner, so sorry for all those questions and thank you for your patience
