how best to resolve this.
synopsis:
existing wall has an SEO with it's existing roof.
existing roof is being "demo'd".
New roof is being designed but existing wall which is remaing, is still reactiing to SEO of demo'd roof.
How best to resolve?

Just like in real life?
The wall in the picture will not grow itself onsite when the roof is demolished.
When you demolish an old roof and build a new one to cover the porch there will be a triangular opening there that a contractor will have to fill somehow with new material.
Shouldn't that area be modeled as a separate 3D element (probably SEO'd wall) with "New Status" and appropriate graphical representation in plan and elevation?
Did I miss something?

yes..I'm fully aware that once a "real" roof is removed, it leaves a gap. thank you for clearing that up.
Now, explain the solid element operation function because I have tried that. I've tried to to SEO from one wall to another and it behaves very strangely.
So, I'd like your explanation of how to accomplish this?

Unless you need super accurate 3d demolished views, why not just offset the existing wall and add a new one to the end?
It is possible to put a small bit of wall there and use one of the triangular opening windows to cut away the bit where the roof is, if you want to be super precise, but it is unlikely to be build like that too.

It was not intended to be that way.
I simply prefer hard-core BIM approach and I would model everything in a project the way it was intended to be demolished/renovated/built on a construction site... hence "as in real life" comment. I subconsciously think this way for the past twenty-something years.
Erwin wrote:It depends on your approach. If I where to do a project in ARCHICAD I would use it as a VCS (Virtual Construction Simulation) platform breaking the future building into real-life-related demolition/renovation/construction processes rather than 2D drawings of the future building. I have a very odd attitude to this, but I believe that with a proper setup and approach ARCHICAD user can eliminate any 2D drafting what so ever.

So, I'd like your explanation of how to accomplish this?
First, I would take a few assumptions.
- I assume this building is not of a brick or stone construction, but a wooden frame.
- I assume demolition will not demolish entire wall frame, but rather remove only studs and structural elements to save cost (even at the expense of constructability).
- Create an existing model of a building
- After talking to general contractor, assume that I can demolish stud walls only in certain places due to original construction limitations
- Using all ARCHICAD tools available to me, I will then find the most cost effective solution to demolishing walls, installing new supports, extending new walls and building new roof.
This approach will eliminate for me any odd triangles you encountered in your model.
See image attached as an example. It is a 3D document (naturally, sections, elevations and plans look accordingly... it is, after all, the same model), and it is not altered in any way as a drawing. Just a saved View of a model.
