The roof. Rectangular lead rooftiles with vertical edges. 8 on top of eachother. Maybe this makes it easier to apply this in your 3D model instead of the idea with rounded rooftiles. The rounding of the roof is also worth looking at. The rest of the roof starts 2 stones above the ballustrade. But at the back end, where it goes around, the roof starts one stone lower. Even the dual spires at the end of the naves differ in dimensions. On the south side the spires with toppings are just as high as the statue on the rooftop of the gable. On the north, these spires are significantly lower than the south ones, if I'm correct just as high as the rooftop without statue. No gables on the west side of the nave towards the front towers is indeed correct. On the south side, the gables go from beginning to end. Once you think you know this cathedral and you try to capture it, you'll discover these differences. Notre Dame is full of concealed imperfections. A perfect example of perfect imperfection. It's actually what makes this masterpiece so interesting.
As you note, there's variation from one part of the cathedral to another, even in parts that might seem identical from a distance. The interior wood trusses of the burned lead roof, for instance, are all different. Builders started on the east and worked toward the west. Each interior truss was slightly different because they were experimenting with which design was most stable. By the time they arrived at the middle of the nave, they had found the ideal form, which they continued to replicate for the rest of the roof. However, in the current reconstruction, the builders are just using the identical roof trusses throughout. There's no perceived need to replicate the experiments and variety of earlier builders. So I've found the claim that the cathedral will be "rebuilt as it was before" to be a noble, although impossible, ideal. The rebuilt cathedral - like my own computer model - will look like the real thing but will, in fact, be different in many of the minor details and personality quirks of the building that are impossible to replicate.
I think the builders can pull it off to make it look exactly the way it did before. With indeed, minor deviations in the interior of the new roof. To make it look the same, you just have to want it bad enough. And as far as what I've seen from these builders, is pure passion, huge ambition, highly skilled people with a very positive mindset, who love what they do and an appetite for impossible challenges. They literaly devoted their lives to save Notre Dame for future generations. As they say "I wake up every day with the honor to save Notre Dame". So I have good faith these people can pull it off: like the fire never happened. Notre Dame will look like it's brand new again. The vaults will be closed in 3 years, wich makes Notre Dame safe enough to reopen. Parts of the roof from east to west and the transcept will also be standing. But the spire will take some more time to make it just like it was before. But, for carpenters and me as a former carpenter/gardener/pavementmaker, jack of all trades, nothing is impossible and there is always a solution. People are still smarter than wood. Shame I was homeless while I fled to Paris and tried to work as a carpenter on the Notre Dame. It failed because of homelessness and lack of money. Maybe I can still do something there in future. Even temporarely voluntary service is in consideration.
