Parametric modelling

Parametric modeling uses parameters to define a model (dimensions, for example). Examples of parameters are:

  • dimensions used to create model features
  • material density
  • formulas to describe swept features
  • imported data (that, for example, describe a reference surface).

The parameter may be modified later, and the model will update to reflect the modification. Typically, there is a relationship between parts, assemblies, and drawings. A part consists of multiple features, and an assembly consists of multiple parts. Drawings can be made from either parts or assemblies.

Parametric modelling uses parameters to define a model (for example length, height, width, colour, thermal properties, positional data) and maintains relationships between different objects to feed data between themselves and hence adapt and evolve the design.

For example if the walls in a room are moved (as well as other walls adapting automatically to maintain a consistent room) the number and/or size or luminaires can automatically adapt to maintain appropriate lighting levels. The parametric information can flow through integrated applications (such as energy models) and interoperable systems (such as procurement systems).
