I have a good one. Some time ago I asked exactly the same question and somebody came up with the solution, but I just can’t find the post. I am trying to generate this shape with grasshopper to make it completely customizable. Is there a way that I can find all the posts I’ve made since I register? Or can somebody give me a hand on how to generate this kind of shape? It is basically creating a polygon and the generating an arc in between each of the vertices. I just want to make an experiment for making a wooden bracelet. after generating the shape I will extrude it and making the bolean difference I just don’t know how to create it. I know that it was not really difficult to make but I just can’t remember how it was.
Yes I tried. But, it just shows the post of the last month. I might have asked about this topic 2 years ago or so, so I don’t know why it is not in my activity :S. But thanks for your help
Thanks Aris!
You rock! I’ll check it out! and try to make it! This is what I made a few years back as a present and I want to make it with grasshopper now, just as an exercise.
Hey,
I think you don’t want a squircle, just a rounded square.
I was trying to do the squircle mathematically when I saw your pictures.
The two shapes look alike but I think a rounded square (cyan) fits your purposes better.
Hey again Aris,
Actually the squircle its OK, as one of the things I wanted to add is kind of “inflate” the square. I want to create an arc in between each vertices and then round that intersections. One thing is that when I bake it makes a lot of points, which is fine, but I don’t know what will happen when I create the surface.
Now I am triying to create an offset and move in Z to then make a loft of those 2 geometries, but for some reason it’s not moving it in Z. I migth be doing something wrong but I’ll Keep trying
I’m trying something else and this is how far I am.
I’m basically creating a Polygon and dividing the curve in the number of segments that the polygon has. Next step is to make an arc from each of the vertices, f.ex. From vertice A to B, B to C, and so on (which I don’t know how to do). I don’t know if it makes any sense or if it is possible to do it this way. Any ideas?
Why manually construct arcs? Use fillet like @HS_Kim
And if you are looking for a shape that has a slight bulge with the arcs you can check out Pufferfish’s Prude Curve component.
Thanks Michael! This is actually super cool!
But how can I control the diameter of the shapes. f/ex. This is for making a bracelet, so if I want the exterior shape to be circumscribed in maximum diameter of 100 millimiters and the interior one on 70 mm. how can I control that? As I understand in this code you can control the length of the curve, which generates very cool shapes for a bracelet like these ones:
