Creating Parametric Families in Autodesk Revit Architecture
Families are the heart of the internal data structure of Autodesk Revit. Every object, whether it is a geometric component, an annotation component, a View or any other component in Revit, is part of a Family. Families come in three "flavors"
Revit Component Families are a unique file type, with an extension of RFA. To create a family, you begin a new file by selecting File->New->Family from the Revit pull-down menus. After selecting the appropriate family template, you'll be placed in the Revit Family Editor. The Family Editor looks just like the normal Revit interface, except that it has a different set of ribbons that include all of the tools that you will need to create your family.
Revit modeling tools can be divided into two main groups: "Helpers" and "Methods". A Helper is geometry that in and of itself does not make up the model in the family, but instead can be used to generate the actual model geometry. Typical helpers in Revit Families are:
Reference Planes - These can be used to constrain Revit Geometry (we'll explore this in just a bit). Reference Planes can also be used as Work Planes.
Work Planes - Every component of 3D geometry in a Revit Family is based to some extent on a 2D sketch. The Work Plane is the actual plane that the sketch is created on. Work Planes can be generated from existing faces on 3D geometry, lines that were already drawn using another plane, or from Reference Planes.
