Complex Multiple Plane Roofs

Conceptual approach: Layout and analyze overall roof flat in plan, then trim up so there's a block for each roof plane, then adjust each block for pitch, then for plan shape, then trim to fit at complex intersections, then extend overhangs if necessary and readjust shape.

1. Lay out the plan shape of the complex roof in rectangular slabs.

2. In a the plan view, analyse where the ridges and valleys occur, and at what angles. Remember that when roofs of equal pitch meet at right angles, the ridge or valley will be at 45 degrees.

3. Still in plan view, slice up the overall roof so that there is a rectangular block, running from fascia to ridge, for each plane of the completed roof.

4. Select the ridge-end side face of each roof block, using the Faces tool, and slide the face upward to the correct height for its pitch.

5. Once each block is at the correct pitch, select the various side faces, and slide the short vertical edges around horizontally (by their mid-edge handles) to change the plan shape without disturbing the pitch of the block.

6. When the plan shapes have been adjusted, the roof should look right except for a few complex intersections.

7. To trim complex intersections, go to plan view, then Group each block needing trimming with itself to be able to make vertical cuts through the already-pitched roof pieces, following specific ridges or valleys as necessary.

8. To extend overhangs without disturbing the pitch of a roof plane, select the main face of the roof block with the faces tool, then double-click the Arbitrary Working Orientation icon to set the crosshair orientation to match the roof plane. Then, select the fascia or lower side face of the roof block, and slide it downward. (This will retain the roof pitch, but may distort the plan shape a little.) If plan shape adjustments are necessary, switch to the normal Plan Working Orientation, reselect the lower side face with the Faces tool, and slide the short vertical edges of the outer corners back outward to meet the shape defined by original ridge line.
