Create pattern component families from the Generic Model Pattern Based Revit family template. You can then apply pattern components to the surface of a conceptual mass.
A square tile pattern grid displays by default. The component template consists of a grid, reference points, and reference lines.
The new tile pattern grid is applied.
The default reference points are locked to allow only vertical movement as seen in the following image. This maintains the basic shape of the component so it will apply to the pattern proportionately. Add points, lines, other geometry, and extrude the pattern to design your component to your specifications.
