comparing two curve lenghts and using the smaller one

Hi,

beast practice is to start with orientated curves or to check the orientation of your closed curves first.

Search the forum for orientate clockwise or orientate manually your initial curves.

If you want to compare something, then compare the areas.

Best,

Raul

Hi Alejandro, 

As Raul says, the best thing is to use consistently oriented curves to be able to offset predictably.

That said, a quick fix would be to:

1. Graft both lists (so there is one value per branch)

2. Use merge to combine both lists (now two values per branch)

3. Find curve length, then use sort these in sync with the curves.

4. Select first element.

5. Trim tree to go back to original tree structure.

Thanks,

Andy

So close!

I would merge the two offset curves together, so they each were on indexes 0 and 1.

 

Then, a List Item which used the "Smaller" component as its Index would pick from those merged curves (because in Grasshopper a Boolean "False" and "True" are equivalent to "0" and "1")

 

This would probably output the one with the largest length, so just use a NOT gate after "Smaller"

 

It's hard to explain in words, hope that made sense!
