Loft failed, don't know why

Hopefully, my question is clear enough, if not let me know so I can formulate it differently. Its just that I really need to this, due to a deadline of the project.Thank you for your help :)

I tried opening that filtre.gh, but you forgot to internalise the inputs. Just right-click on them, click "internalise data" and then save again. Otherwise I can't have a look, because the inputs are empty. Alternatively you have to send the Rhino file as well, but the internalise data thing is the standard on the forum.

Can you just say again where the problem is occuring using a screenshot.

Normally I did internalise the data, but I suppose something went wrong. But now for a reason I cant figure out, I cant open it any longer...It crashes instantly , might have to recreate it.

Either way here is the rhino file. its these curves that I want to use as basis.

Hm, ok so I had a quick look. First off you forgot to graft right at the beginning in the 2 components. Thats probably why it crashed, because it was multiplying everything:

You have to make sure you have matching data structures that go into one component unless you specifically want to cross them, ie. do every operation with every value of input A with every input of input B.

Secondly I am not really sure what you are trying to do. You have so many curves that end up going into the loft component, of course its going to fail. You cant loft just a random assortment of open and closed curves that are selfintersecting. It works with lines that are either all open or all closed. If you look at all the curves and cant imagine how it would look if it had a surface over it, then Loft will usually fail.

You should try and do something a little more simple first, like just having a bunch of curves like in the example but maybe change how they look. Why that strange input and then building curves out of it?

Well, since I can't open the file, I can't "un-graft" , It crashes instantly, and it closes, by so I don't have any access to the file

:(  thing is that this shape looks more like what I need for my project, thus I am just thinking of taking and rebuilding the shapes that i have , so that I can create my own shape,following the idea from the example above. It doesn't have to be all the curves, at the limit, it could be just 3 curves(tubes) which would be copied afterwards , because the 3 tubes would have different thickness.

Hm ok. There is an option when you open a file to "lock the solver". This will open the file without trying to do any calculations. You can then do all the changes and reenable it when you right-click anywhere and click "lock solver" again.

Also I dont think its crashing, i think its just calculating for a long time. Keep having a lookout for components that multiply data without you wanting that. Also sometimes just let it run for a while. The file opened fine on my computer.

What I find with examples is that it a lot of times makes sense to not reuse them, but take some of the basic ideas and rebuild what you want from scratch. It doesn't take so long and you learn a lot while doing it.

well it automatically closes as I try opening this file. Thus it doesn't even open.
