Designing a hexasphericon

Hello Everyone,

i want to create a hexaspericon. I tried it. But my problem is extruding the surface along a circle.
hexa_grasshopper

But i have seen there a always many ways to accomplish something in grasshopper so if you have another way to do create a hexaspericon. I am also intrested.

Thanks in advance!

Kind regards
Tobias

Welcome @tobias.stach,

Have you tried sweeping along your arc like this:

Next time, don’t forget to provide a definition (GH file), since it facilitates providing help and is even kind of mandatory in this forum to get assistance!
I also invite you to read up on how to ask effective questions here.

A hexasphericon isn’t quite that simple @HS_Kim. Half of it is rotated sixty degrees to create a continuous surface:

Thank you for letting me know and I found out that there was a toy like this for the first time.
But why did @tobias.stach checked it was solved?
Anyway, modeling isn’t that complicated.

I was puzzled by that too, since he apparently checked my post, then unchecked it:

Agreed, modeling isn’t that complicated.

I am new to this forum. I tried to give “Solution” to your answer and the first. But it always turned off one Solution. Anyway.

@tobias.stach, don’t worry about it. We’re not in first grade here, although some people seem to be competing to become teacher/OP pets.
@HS_Kim probably merits the solution best, since he provided a way to construct a real hexasphericon with his second reply. I guess I interpreted your question a little different yesterday. To me it seemed like you were simply looking for a way to “extrude the surface along a curve”.

By using the same logic and Bezier Span, easily implement the form shown on the video in the post of @Joseph_Oster .
If you combine polygon side numbers and angles, you might be able to experiment with different variety of forms.

Pretty cool.

I started playing with that idea in your model, then retrofitted the rotation angle calc to my model. Surprisingly effective!

In your model, I found that any value greater than ‘1’ for the ‘B’ slider (needs a better name) causes Extend Curve to fail when the number of segments is increased:

1. The negative extension length is longer than the curve
