19 | | -A pillow vault is a type of vaulted ceiling with convex, pillow-like sections, often formed by intersecting barrel vaults or domes, creating a smooth, rounded appearance. It is a simplest example where all mesh boundary vertices are set as supports. |

25 | | -## 1. Create Pattern |
26 | | - |
27 | | -**Command:** `RV_pattern` > `RhinoMesh` |
28 | | - |
29 | | -Create a pattern from a mesh. You can start with the attached Rhino file or a session file. |

38 | | - |
39 | | -**Command:** `RV_pattern_supports` > `Add`> `Manual`> `Select Vertices` |
40 | | - |
41 | | -Manually set the boundary points on the top and bottom edges of the mesh. |

51 | | -**Command:** `RV_form` |
52 | | - |
53 | | -The mesh geometry is converted into a line preview, marked with green lines. |

61 | | -## 4. Force Diagram |
62 | | - |
63 | | -**Command:** `RV_force` |
64 | | - |
65 | | -On the right side, the force diagram is created with TextDots marking the angle deviation between the form edge and its 90-degree rotated force edge. In the next step, horizontal equilibrium will be applied to reduce this deviation to zero. |

73 | | -## 5. Horizontal Equilibrium |
74 | | - |
75 | | -**Command:** `RV_tna_horizontal` |
76 | | - |
77 | | -Leave default parameters as is to reach the horizontal equilibrium. Since horizontal segments have almost no force, the force diagram collapses to a line. |

85 | | -## 6. Vertical Equilibrium |
86 | | - |
87 | | -**Command:** `RV_tna_vertical` > `2` |
88 | | - |
89 | | -The final geometry is computed by running the vertical equilibrium command, change the height to 2 to match the preview. For preview, we use the following options:`RV_settings > Drawing > show_pipes` and `show_forces`. |
