I was recently asked how to produce a more detailed Revit model where the tiles are shown in more detail than can be represented than a basic slab and hatch pattern, and without having to embellish sections or elevations excessively with additional 2D detailing.
For many years Revit contained its massing tools which can be utilised to model organically formed roofs and walls as well as bespoke pattern-based curtain systems.
Fig 1. Using a pattern-based panel approach to model roof tiles.
The pattern-based curtain system could be used to layout an array of tiles as they do form a grid system of sorts following rows and battens.
Whilst I wouldn’t recommend this approach for larger scale models the results can be satisfactory for smaller house type models or where a model might need to be provided at a higher level of detail for fabrication workshops.

The first step is to model an individual curtain panel (pattern based). Choose the rectangular grid option and set a suitable interval for tile arrangement. Then create and constrain reference points and lines to form a framework for the desired tile. Model suitable geometry to form the tile element.

Once tested, load the tile family into a project. Create an in-place mass, create a form, and select the faces that are going to represent the roof. Choose Divide surface from the ribbon menu and select the rectangular grid pattern. This layout can be used at the initial stage just to check; the pattern start position and spacing to provide a quick preview of how many tiles or panels will be generated.

Staying in the in-place mode, browse the type selector drop down list and select the custom pattern which will be the name of the pattern-based tile saved previously. Ensure the spacings are set as per the family parameters. Once applied the arrayed tile layout will appear. Do allow a little time for the software to refresh the screen, depending upon the model size and workstation specification, it may take some seconds to process. TIP: To improve performance when editing grid spacings supress the geometry display. Once complete the geometry can be re-enabled and should display as per figure 5 below.

By using Shared parameters these tiles can be scheduled with values listed for dimensions, materials, and other properties as required.
