Loft with guide curves

Grasshopper
1

Hi All,

I’m trying to make an irregular bowl shape - it’s using 2x profiles - and upper and lower, with guide curves to help define the walls of the bowls.

I’ve tried using the loft command, but it doesn’t appear to have any control over the start/end/profile tangencies.
I tried Conrol Point loft, but it seems to only pass through the first profile. The last profile is just a guide. Changing the degree doesn’t help either.

There’s too many guide curves for the sweep2 option.

Here’s my GH file so far.

Note - the guide curves aren’t strictly necessary. But I do need some control over the shape of the walls, especially the start/end tangencies.

Any suggestions?

you’ll need to internalize your geometry:

Could you explain further? I don’t understand what you mean.

You are referencing data that is not included in the definition.
The orange components on the left in my image are referencing points
Right click these and use “Internalize data”

That had no effect at all.

Maybe you did, and the file you uploaded is older. This is what I get:

Oh good point… it relies on the rhino model to go with it.

Will update original post with internalised data (DONE).

Sorry for the confusion.

Thanks for that. I had looked at doing that method, but I couldn’t make it work.

I’ve added some scalars for the tangency vectors, and it’s looking great now. Thanks
