Double-Layer Space Frame

Barrel-vaulted double-layer space frame roof

Two point grids are built with grafted Construct Point: the bottom layer on the full module and the top layer shifted by half a module. Heights follow a sine function so the roof curves like a barrel vault. Every top point is connected to its four nearest bottom points with Closest Points, and chord members come from data tree branches plus Flip Matrix. Members are piped and nodes get spheres.

Components and plugins

Components used

Series
PolyLine
Flip Matrix
Closest Points
Line
Pipe
Sphere

Plugins required

None. It uses only the components built into Grasshopper.

Parameters you can change

Module (1 to 6): grid module size (m)
Count X (3 to 20): modules in X
Count Y (3 to 16): modules in Y
Depth (0.5 to 5): distance between layers (m)
Vault Rise (0 to 12): barrel vault rise (m)

How the definition works

1Set the sliders in the Parameters group (Module, Count X, Count Y, Depth, Vault Rise).
2Bottom layer: X and Y coordinate series, sine height from X, and grafted Construct Point form a tree grid.
3Top layer: The grid is shifted half a module and raised by the depth, one row fewer in each direction.
4Members: Chords from PolyLine per branch and Flip Matrix; diagonals from Closest Points N=4.
5Pipes & nodes: All members are merged and piped; top and bottom nodes get spheres.

Frequently asked questions

Do I get the real file?

Yes. The pictures on this page are only previews. After payment we send the download link of the real project file (a ZIP containing the .gh and .ghx definition, the baked .3dm, images and a BACA-DULU.txt note) by WhatsApp or email.

Which Grasshopper version do I need?

The file was made in Rhino 8 with Grasshopper (Rhino 8). Newer versions open it too.

Can you adapt it to my design?

Yes, as a separate order. Message us on WhatsApp with a short description of the size and shape you want.
