Panelling From Point lists

Hi all,

I was wondering if someone could help me with producing two separate panelled surfaces/breps from these point lists. I've done it before by creating polylines then lofting them, however this has thrown up problems and ideally I'd like to have separate facets which I can use later. I know there's a way to do it by shifting lists and then creating rectangles which can be fpatch'ed but I can't work out how to manipulate the data in the right way.

Thanks for your help,

Laurens

Hi.

You've been asking similar "question" the last time.

Where did you get these points data and make it harder to create faces in grasshopper?

It's better to avoid to use GH for a result that is not parametric at all.

If the point data you've created is in some 3D software, why don't you create a face directly there?

Hi Hyungsoo,

Thanks for the reply, I was ideally looking to avoid using the loft component and get the panels through manipulating the list of points, I've managed to get this so far. Do you know a way to avoid having to explode the tree?

Code attached.

'Partition' in the upper left group is used to separate the two sets of curves: seven in one list, three in the other. Then 'Loft' is applied two different ways; 'Loft Options' with 'T=4' is "Developable", meaning flat facets instead of curved surface.

A copy of the curves is then moved down for better visibility and 'BANG! (Explode Tree)' is used to separate the two branches. This is necessary for what follows ('Flip') because one set of curves (7) has six points each, the other set (3) has five points each.

'Explode' is used to break the polylines into segments. 'Flip' is used to get the segments by column instead of row. 'Loft' then produces vertical surfaces from each column of segments.

'Entwine' is used to combine all the loft results for selective viewing using the 'Tree/List Viewer'. Try all the combinations possible with the two sliders to see them all.
