It seems Iran (rejim) will soon face the music; this way, they will feel what it is like to be defenseless! This would be the finish point to a chapter of history! Let's see and hope to meet in a free Iran!
I appreciate all good memories, help, support... You made here...

Thanks for your feedback. I will develop the idea and share more soon.

It has been some time since I have been busy with a revitalizing approach to the arched and vaulted structures, reimagining them in contemporary or future contexts. I think the same process is applicable in timber roofs as well, and here is the process I go for (reviving the system):
Simplifying the question (system) and breaking it down to aspects,
evaluating those aspects and their relations (validating the system),
reimagining them based on the previous steps.

One of the core concepts of the roof question (IMO) is to break down a wide gap into smaller spans. The other is to break it into triangles and rectangles and cover those shapes. There are specific "types" of roofs, and they combine in "specific" grammar.
There is a mainstream tradition regarding the latter question, and here lies my answer: what if we think differently and combine the "types" in a different "grammar"?
Arches and timber roofs share a very similar approach to span the gap as a roofing system, which is why I strongly believe these steps apply to timber structures as well. We can revive those "specific" types and their "grammar" to reach novel combinations.
Here is a glimpse of the idea (pattern) I follow.
Please leave your comments and let me know if any description is needed.
(Can you see the logic shared in the first two images and follow the logic behind the rest?)

somehow similar to this:

and this other C :

I polished some of old sketches. These ones are the letter "C":

@MtnArch
I hope D. Trump makes the best decision, not wasting time and money. Iran ( I mean people of, not this governing bullshit apocalyptic ideology ) could be one of the best allies of the US and EU.
Otherwise, it turns into another North Korea...
Also, I hope to have the chance to relocate to the eminent land of the US. My situation is slightly better than your architect fellow . I know a bit of English and am a fast learner to get the hang of wooden structures , hopefully.

P.S. The Internet is still unstable, so I may not be able to reach out regularly.

Wireframe plz.. any description of the process?

Thanks @tig , thaks a million. I hope everything goes smoothly. I think world/EU has no more space for another wave of migrants/asylum seekers.

Thanks @bep @l-i-am @mike-amos and @mtnarch for your cooncerns.
It seems this is gonna be the last presence of the US in the Middle East for at least the next 2/3 decades. It will not waste his time flirting with mullas.... Their ideology is dangerous. I hope that world takes Iran's story as a lesson, not letting an ideology (especially Islam) take over... IMO World would be a much better world if ruled by wisdom and knowledge. Islam (to my understanding) has never been the religion of peace.... When I see Muslem extrimist in EU or US, I feel upset, and wish EU/US prevents its growth.
@mtnarch people of Iran, mainly, like and admire US people. Many of my good/smart friends had to emigrate to your eminent land. Who knows, maybe I had to/opt to either...

No exact number/data of lost lives... ranging from 23000 to 40k+... even 1 life is too much letalone tousands... and they were mainly young.. I was out and saw familes all together protesting .. it was in silent at first, directed to violance...

Mates, mates... You made me burst into tears. Internet blockage was severe, and it is somehow back (many new websites are added to "out of reach list"). A hole Iran is suffering a big trauma... many lives lost, brave, beautiful young people.... unlived lives.. unflourished futures... fighting for a simple life.. so that ends meet... is it too much?...

Iran is suffering a big trauma... many lives lost, brave, beautiful young people.... We were out, no one knew the other yet feeling integrated...

it is fierce mate. Thanks . lets hope for positive changes.. and a lasting peace in world.

Unbelieveably good!

Thanks for the update, though I have issues with it. Here is what I get:

I uninstalled the previous version, then removed the entire plugin and its loader and reinstalled it, yet the issue persists.

Merry Christmas, mates, let's pray for a more peaceful world!
