Swoosh Pavillion script is not working

[Sven_001 (Sven)]

Hello everyone,

I recreated the Swoosh Pavilion script that was shown in a YouTube tutorial (https://www.youtube.com/watch?v=I4AofPk0Mss&t=7s). Most parts work as expected, but the cross members do not behave like in the video. Their orientation and spacing change in a way that I cannot control.

I checked every step of the definition and compared it with the tutorial. I have not found the point where the issue starts. I would like to know what usually causes this problem in similar setups and where I should look more closely in the script.

Thank you for any advice.

That’s more like curing the symptoms than the problem, isn’t it?

@Sven_001

You did not pay attention to the curve direction or order of the curves you imported to Grasshopper. If you join and explode them, this will be solved:

You will then have to Reverse List the first Graph Mapper or build it’s curve in reverse:

To eliminate the roll over effect of the blocking members:

You will have to discard the last branch of of them. That can be done like so:

Here is finding the rotation plane:

Though you may want to modify the last arc to a full semicircle before offsetting:

Structure would not have stability otherwise.
