Chief Architect does not natively auto-build this specific framing detail. However, you can achieve the desired result using a couple of manual workarounds. Method 1: The Double Roof Plane (For 3D Accuracy) This method involves manually drafting the tails so they render correctly in 3D section views. Create a Second Roof Plane: Use "Copy and Paste in Place" on your existing roof to create a second plane strictly for the overhangs. Switch to Manual: Turn off auto-rebuild and switch to manual framing. Adjust Structure: Change the framing structure of the overhang roof plane to a 2x6. Align the Framing: To align the 2x6 tail to the side of the I-joist, manually shift the "rafter tail" roof plane over by the exact thickness of the I-joist. Note: Doing this may slightly misalign the roofing material textures between the two planes. Blocking: You will still need to manually add 3D solids to represent the blocking between joists at the top plate. Method 2: The Visual Approximation (For Permit Plans) If you do not need the 3D framing model to be perfectly accurate and just need the exterior to look correct for elevations, use this faster method. Adjust Structure: Change your roof structure thickness to match the I-joist. Rafter Settings: Leave the "Rafter Construction" set as a standard rafter. Fascia: Set your sub-fascia to 5 1/2" (to match the 2x6). Options: Uncheck "boxed eave." CAD Detailing: Because the 3D model won't perfectly reflect the hand-framed reality, rely on 2D CAD cut sheets and details to show the plans inspector and your framing crew the actual I-joist to 2x6 connection.
