Creating Eaves for Buildings with Pitched Roofs in SketchUp

By Aidan Chopra

A great way to create eaves, or roof overhangs, in SketchUp is to use the Offset tool. Follow these steps to get the general idea:

  1. Make a group out of your whole building before you start modeling the roof.

    This keeps your roof separate, which in turn makes your model easier to work with.

  2. Use the Line tool to create an outline of the parts of your roof that will have eaves of the same height.

    The goal is a single face that you can offset. A lot of buildings have complex roofs with eaves of all different heights; for the sake of this step, just create a face that, when offset, will create roof overhangs in the right places.

  3. Use the Offset tool to create an overhanging face.

  4. Erase the edges of your original face.

    Here’s a quick way to do this with the Select tool:

    1. Double-click inside your first face.

      This selects both the face and the edges that define it.

    2. Press Delete to erase everything that’s selected.

  5. Push/pull your overhanging roof face to create a thick fascia.

    Different roofs have fasciae of different thicknesses; if you don’t know yours, just take your best guess.
