How to Draw a Cornice Return, Step-by-Step:
Before You Start - Cornice returns should be drawn last. Make sure that the main sections of the roof are sketched and that all facets are closed. Select the Facets tab to ensure that the facet the cornice return is under is shaded blue, as shown below:
Step 1: Switch to the Draw tab and draw two boxes using the Unlined line label.
Step 2: Then apply the exterior line labels.
The exterior line running parallel with the ground is an Eave.
The exterior line running along the slope is a Rake.
Step 3: Next, apply the interior line labels.
The line running parallel with the ground, where you would apply apron flashing is a Wall.
The line running along the inside slope, just under the Valley, is a Step.
Step 4: Switch to the Facets tab to make sure your cornice return facets are enclosed. It should be a darker shade of blue than the facet it's sitting on. While you're here, apply the pitch value within the Facet Labels menu.
Step 5: You'll need to adjust your connecting lines. We'll start by moving the Rake/Eave line of the cornice return to be in line with the facet above.
To adjust your line - hover over the point in the center where your Rake connects with the Eave. Your curser will turn from red to green.
- On a computer (Web App), right click with your mouse or two finger tap with your track pad and the curser will turn blue.
- On mobile (iOS or Android), hover over the point until the curser turns blue.
Step 6: Pick up the point where your Rake and Wall lines meet, extending it inward 1 foot.
We recommend 1 foot, as it is the length of a typical overhang. You can adjust this in the app if a cornice return is deeper during your on site inspection.
Step 7: Pick up the point where your Eave and Step lines connect. Drag it over to the point where the corner of the gable meets on the roof above the cornice return (Rake, Eave, and Valley in the image below).
Step 8: Pick up the point where your Step and Wall lines connect. Drag it just inside of the Valley along the top of the roof.
Step 9: Click on the Facets tab. You should see dark blue shading where each cornice return is located. This means you are accounting for the shingled area squares on the gabled section of the roof, as well as the shingle area for the cornice returns.
