Introduction
This is the final result of this episode, a gable roof with a 30-degree slope, a 60 cm eave that also covers the porch, and front and back gable walls that are cut precisely to follow the bottom side of the roof. Let's start. Hello, welcome back to the ArchiCAD House Series. The floor, porch, columns, and beams are already complete. Today we are creating a gable roof using the roof tool, mirroring it, and then cutting the gable walls to follow the roof shape using the Trim Element to Roof command.
Step 1: Roof Tool Setup
Double-click the roof tool. Single plane geometry method, which is one roof plane. Slope of 30 degrees, thickness of 200 mm for the frame and roof tiles. Elevation of the support line, pivot line, 3000 mm, same as the roof peak. Click OK.
Step 2: Support Line & Roof Plane
Draw the support line first, click from the outer left front wall corner to the outer left rear wall corner. Then click inward to determine the side of the roof that rises. After that, draw the outline of the roof plane, starting 600 mm outside the wall as the eave, up to the ridge line in the middle at 4 meters, and from the front porch to the rear eave.
Step 3: Mirror a Copy of the Right Side
The right side is sufficient to mirror. Select the roof plane, open the edit menu, move, mirror a copy, then click two points on the ridge line. The two roof planes meet precisely at the ridge line at a height of 5.35 meters. Open window 3.
Step 4: Roof in 3D View
The roof is formed, but the front and back walls are still 3 meters high, so the triangle under the roof is open. We need gable walls. Return to the plan, select the front and back walls with shift click, then change the height in the info box to 5.600, higher than the ridge.
Step 5: Ridge Wall Trim to Roof
In window 3, the wall cuts through the roof. Now open design, connect, trim element to roof, select the part above the roof to remove, and click OK. The wall is neatly cut to form a gable triangle.
Step 6: Complete Exterior
Orbit around the house. The gable roof covers the front porch, the eave protrudes 60 cm on the side, and the gable wall is perfectly closed. Our house exterior model is now complete. Save with the S key.
Done!
Done. We have created a gable roof using the roof tool, used the mirror command for the second side, and trimmed the gable wall with the trim element to roof function. In the next episode, we will name the rooms using the sound tool and arrange the furniture. Working on a house design, architecture studio task, or civil engineering final project?
