Perfect vaulted arches

For ages I've known the shape of a vaulted arch, but recently I thought I'd see if it could be made in Dromed using cylinders instead of wedges.

Very nicely explained!

I just did another test and they still work when they intersect at right angles.

E.g.

How beautiful! I was just experimenting trying to achieve something similar, but I like this technique much better.

For the gothic vault like this You use longers cylinders with intersections ?

How many cells it's give for this room ?

R Soul is genious, but i don't know why anyone had doing this before because it's the fundamental of the gothic arcs and vaults geometry of medieval architects... Maybe dromed limits before New Dark, i know, but we wait 2016 for this ! ^^

Yes, long intersecing cylinders, but the building order is important. You need to start with the 1st example, building a complete arch, then build another complete arch etc.

The room has 406 cells, but if I remove the stone textured caps from the columns, top and bottom, it goes down to 273.

It wouldn't have been worth doing this with the original Dromed. With 10 sided cylinders the result is about the same as using a single 10 sided cylinder aligned by sides, or even 8 sides, aligned by vertices.

I thought of trying this when I was looking for arch textures. I saw an example of someone making those arches in Blender by removing some vertices from thick-walled cylinders. Then I looked up the formula.
