Timber Framing Design
Plan E Overlays
| Calculation layout | Roof Frame Overlay | Roof Strutting Overlay |
| Ceiling Frame Overlay | Roof Area Supported |
The same principle as shown for the overlays for Plan E applies for all other exercises
The illustration for Plan E is an example only. There are a number of other layouts possible.
You may use another design configuration and then compare the sizes and quantity of timber.
