Help with fillet curves

He,

Im working on a thing here, but something is unclear, I have joined curves together in two ways and I would like to give these a fillet, but some if the corners just don’t change. Also if you look at the pipe segment the curves don’t really look like their connected. Any tips for this?

Dear @stijnvanaardenne

please post a minimum version that shows your question / problem.

maybe also write some scribbles / notes into the definition so it is easier to read for others.
(and /or group and name portions)

for others that dig in:
Pufferfish is needed, download via food4rhino

Hi,

Thank you for the quick response! Ok this file is a bit more clearer I think. I cannot take away stuff because this might have an influence on the solution I think; I am not sure where the problem is coming from so I want to show the whole thing.

Dear @stijnvanaardenne

i think it s more a geometrical problem:

(left) let’s look at a horizontal arc and a vertical line.

(middle) as soon as we remove a portion of each curve and look at the transition (red) - this is not a planar transition / not an arc or fillet, its a 3d curve / blend / _blendCrv.
look at the (cyan) tangent, it is not in the same plane as the vertical blue line.

(right) if we do not shorten the horizontal arc and move the vertical line - we can add a 90-Degree arc (green)

of course now (middle) and (right) will _pipe without a problem.

to solve your problem:

(a) if you want to stay with filleting / true arcs, you need to insert straight sections.
(b) But I think its more the Design-Idea to shorten the curves and insert a _blendCrv transion.
(c) if this is just a fast sektch, you may want to try SudD Multipipe

Hi,

Thank you! OK it is clear for me know how to do this, Ill try the B option and use the curve blend!

Thanks a lot.

the Extend Curve component will allow to shorten curves, use a negative value !!!
