What is parametric families in Revit?

If you want a family that can change size or has moving parts, create a parametric family –that is, one that uses parameters to control its behavior. In this case, you need to build a framework using reference planes and reference lines.

What is System family in Revit?

System families contain family types that you use to create basic building elements such as walls, floors, ceilings, and stairs in your building models. … System families are predefined in Revit and saved in templates and projects, not loaded into templates and projects from external files.

What is view specific elements in Revit?

In projects, Revit Architecture uses 3 types of elements: … Datum elements help to define project context. For example, grids, levels, and reference planes are datum elements. View-specific elements display only in the views in which they are placed. They help to describe or document the model.

What is project Datum?

On a construction project, a datum level is an arbitrary horizontal plane of reference from which all vertical dimensions are measured. It can show the vertical height difference between floor levels of a building as well as differences in levels between one part of the site and another.
