1a. Create pattern
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, 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 RV2, 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.

Pattern Object
Pattern is a COMPAS mesh object. A mesh datastructure is network of faces, where the connectivities of the faces are defined by halfedge adjacencies.
