Fat Pencil Studio's modeling process for construction details was inspired by Dennis Fukai at insitebuilders.

The key is to create a SketchUp model in the same manner as you would construct an actual building: add structural elements first, finishes last, and keep all the systems in between carefully organized.
Here are a few examples of construction details we've done recently:
