Sweep rectangular beams along a curved surface

[Lana_Dang]

Hello,

I am having difficulty sweeping a rectangular shape along vertical and horizontal curves made from a curved surface. I divided my surface into multiple planes specified by a specific spacing and tried to use those curves as the rails to my sweep. They all should share the same rectangle base shape.

If anyone has a more efficient way to create this in grasshopper, any tips are welcomed!

Thanks

You flattened your data tree in Orient Direction - so then you were asking Gh to sweep 552 curves (and some nulls) along 23 rails

You could try something like this instead

don’t flatten

• cull nulls.

Thank you for all the helpful tips. I tried this in the other direction and received the same error. The error message reads that the parameters are out of bounds. How shall I go about this?

Also is there a way to do this sweep with existing curves in rhino rather than curves made from grasshopper?

Thanks in advance!

Just Graft the curves at the start - that way Grasshopper can tell which Sections and Rails are related
