Rhino "Fin" command
Hi, Has anyone managed to emulate rhino's "Fin" command ? Through a custom component, VB / C# components, or just by using normal components ? Thanks,KayinSee More

I tried to do contour lines and loft the, but its ot the same exactly..maybe its best to use tsplines for amorphic shapes

David,
What then is it about the coding of Rhino that makes it difficult to work with trimmed surfaces?

Hi, im here again lol. anyways i have found the tool where i can get the normal of the intersecting interpolated curve on the surface. however, when i fin the surface, it seems that the fin is not to the normal any ideas to make it 100% to the…

Hi, i was searching for a way to fin my curves on a surface too. but this time my curve is not divided from the surface itself using the divide surface command in GH which definitely gives me the Normal of each curve. The curve that im using is a…

A way to do this without scripting would be to run a dense polyline through the curve, then Reduce it to a given accuracy. This would automatically result in more (shorter) segments near highly curved portions. Then you either use the Polyline…

Ah, just the someone else I was thinking of...
The only other idea I can think of would be to iteratively evaluate curve curvature (or maybe surface curvature) to increase the sampling rate at locations with extreme curvature. This would definitely…
Damien Alomar replied to Kayin Dawoodi's discussion 'Rhino "Fin" command'
As Taz says, you have to sample points to ge the normals, there's just no way around it. The decision as to where to add points to the fin is based on testing to see if the resulting curve/surface is within tolerance. If it is than it can be…
taz replied to Kayin Dawoodi's discussion 'Rhino "Fin" command'
I'm not sure how the fin command works, but I can't think of a way of replicating it in GH without sampling points from a surface to get the normal vectors.
Maybe someone else can weigh in.

Thanks Taz,
I like this definition a lot !
But I am looking for something a little more vague, the sort of 'notion' of a normal 'sweep' of a curve on a surface giving the fin, but I guess this is not possible ...
To visualise,…

This might help get you started.
Fins are interpolated based on sampling surface normals.

Any further developments on this topic ?

Well that depends on the trim curves. If the resulting surface is sort of rectangular, then you can probably make an untrimmed surface that looks about the same. But it's definitely not possible if the trimmed surface has any holes or more than…
Kayin Dawoodi replied to Kayin Dawoodi's discussion 'Remap trimmed surfaces, to make them untrimmed surfaces'
My bad, I did not explain myself well...
I mean that once you have created a Trimmed Surface, use that new surface as though it were an Untrimmed Surface.
I had done this before by plotting lots of points on the trimmed surface then either using…

Untrim
Shrinking involves removing all the control-point rows and columns that are outside of the trimmed edge and thus do not affect the shape of the surface remainder.

Remap trimmed surfaces, to make them untrimmed surfaces
Hi all, Is it possible to make a Trimmed Surface be recognised as an Untrimmed Surface in either Rhino and/or Grasshopper ? I have tried the Rhino Command "ShrinkTrimmedSrf", but it is not good enough. Has anyone done anything like this ? Thanks in advance ! KayinSee More
