Grasshopper

algorithmic modeling for Rhino

1. A list of closed planar cuves goes into a BoundarySurfaces.

1. Same number of surfaces come out, one for each boundary curve, but the order of the items shifts at list item number 44 for the surfaces....

 

Am I doing something wrong?

PS: I am working around it by grafting>BoundarySurface>Flatten; and it behaves as expected

 

Hi Gui,

you're not doing anything wrong. The Boundary component does not retain list order. This is because it operates on all curves at the same time. If some of the curves were coplanar and nested, then they both end up as trims of the same brep.

If you want to create a single surface per curve, then just plug the curves directly into a Surface parameter, no need for a component.

Interesting. Good to know.

What was strange was that 99% percent of them stayed in the same order as before... except 2 or 3 out of the 600 shifted places in the list... : /
