+# Barrel Vault

+<figure><img src="../../.gitbook/assets/examples_pillow_vault.png" alt=""><figcaption></figcaption></figure>
+
+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.

+
+## 1. Create Pattern
+
+**Command:** `RV_pattern` > `RhinoMesh`
+
+Create a pattern from a mesh. You can start with the attached Rhino file or a session file.

+***
+
+## 2. Identify Supports
+
+**Command:** `RV_pattern_supports` > `Add`> `Manual`> `Select Vertices`
+
+Manually set the boundary points on the top and bottom edges of the mesh.

+
+## 3. Form Diagram
+
+**Command:** `RV_form`
+
+The mesh geometry is converted into a line preview, marked with green lines.

+
+## 4. Force Diagram
+
+**Command:** `RV_force`
+
+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.

+
+***
+
+## 5. Horizontal Equilibrium
+
+**Command:** `RV_tna_horizontal`
+
+Leave default parameters as is to reach the horizontal equilibrium. Since horizontal segments have almost no force, the force diagram collapses to a line.

+
+## 6. Vertical Equilibrium
+
+**Command:** `RV_tna_vertical` > `2`
+
+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`.
