| # 1a. Create Pattern | ||
|
|
||
| The first step of the workflow is to generate the topology of the `FormDiagram`, which is called the `Pattern` in RhinoVAULT. A `Pattern` is a collection of vertices interconnected by lines, represented by the COMPAS [mesh datastructure](https://compas-dev.github.io/main/api/compas.datastructures.html#meshes). | ||
|
|
||
| RhinoVAULT offers several methods for generating a `Pattern`. Each method has a direct influence not only on the topology of the eventual shell structure, but also the type of application and interaction that is desired during the design process.  | ||
|
|

|
|
||
| There are many ways to generate a topological pattern. Each method has pros and cons, and the desired design or workflow will help determine which method is more appropriate. | ||
|
|
||
| In the case of the rib layout variations for the [rib-stiffened funicular floor system](https://block.arch.ethz.ch/brg/research/rib-stiffened-funicular-floor-system), the boundary remains fixed (the footprint and depth of the floor). However, depending on the topology of the form diagram, the distribution and flow of forces change drastically.  | ||

|
|
||
| In RhinoVAULT, three types of Rhino geometries can be used to generate a `Pattern :` Lines, Mesh and Surfaces. These pattern generation features would be particularly useful when there is already an existing structure with a geometry that one would like to recreate the pattern for. | ||

| {% hint style="warning" %} | ||
| `Pattern` is a COMPAS [mesh](https://compas-dev.github.io/main/api/generated/compas.datastructures.Mesh.html#compas.datastructures.Mesh) object. A mesh datastructure is network of faces, where the connectivities of the faces are defined by halfedge adjacencies.  | ||
|
|
||
|
|
||
| {% endhint %} | ||
|
|
||
| ### RhinoLines | ||
|
|
||
| One of the simplest, and the most manual, way to make the Pattern is to draw the edges of the `Pattern` as Rhino lines. Each edge of the Pattern should be an individual line; all lines should be broken at all line intersections. In other words, these lines may not be overlapping.  | ||
|
|
||
| <figure><img src="../../.gitbook/assets/from-lines-grid.jpg" alt=""><figcaption></figcaption></figure> | ||
|
|
||
| The input set of lines must consist of closed loops of lines representing the faces of the `Pattern.` If there are closed loops of lines, a `Pattern` will be generated and all lines that do not form a closed loop, such as the "leaf" edges will be omitted. | ||
|
|
||
| <figure><img src="../../.gitbook/assets/pattern-input-lines.png" alt=""><figcaption></figcaption></figure> | ||
|
|
||
| ### RhinoMesh | ||
|
|
||
| A Rhino mesh object can be used to create a `Pattern`. Since a Pattern is also a mesh object, the vertices and edges can be directly used to create the vertices and edges of the `Pattern`. | ||
|

||

|
|
||
| ### RhinoSurface | ||
|
|
||
| A non-trimmed Rhino surface object can be used to create a Pattern, using subdivision values for U and V. | ||

|
|
||
| ### MeshGrid | ||
|
|
||
| This function automatically generates a mesh grid using number and size of the grid in x and y directions. | ||
|
|
||
| ### Triangulation | ||
|
|
||
| Not implemented. | ||
