# Assemblies
Assemblies are defined as a collection of elements (or members). They provide a way to consider a collection of elements, such as a building core, as a single beam like entity. Results for assemblies are calculated by aggregating the results from the elements defining the entity.
For each point along the length (x axis) of the assembly a ‘cut’ is made through the elements and the results across this cut face aggregated.
