An Archimatix model (AXModel) is a collection of parametric objects. Each parametric object, a smart piece of geometry creation, iteration or manipulation, is represented in the Archimatix editor window as a palette with parameters that have controls. These controls may be linked with others to set up dependencies.
Parameters represent values that are used to operate on mesh geometries. Parameters may be of various data types which match Unity’s data types, including float, int, bool, material, etc.
A float is a decimal number. It is most commonly used for values in dimensional space. For example a window height or a building width.
Integers are best used for discreet values such as the count of things. For example, the number of windows across a facade or the number of floors in a building.
