I am trying new ways to Rad-Bend sheathing and framework intact.

My overall shape needs diamond shaped coffers for a vault with smooth surface on top.

I have tried many ways to shape the basic structure, over the years.

Here is an effort to use T-Subz first, which gives excellent tiangulation for coffers, but...



To avoid this problem i try the "Keep Edges" option of Union tool first. I have found several nice outcomes working with coffer surface objects as surfaces only.

Currently i am trying to get the proper 'thickness'... The Thicken tool cannot compensate for self-overlapping when thickening the joist-surfaces alone.... So somehow, i need to Rad-Bend whole solids having protruding framework on one surface, but smooth on a parallel surface.


I think this was the best result of that effort, but it has unwanted geometry.
Please advise. Thanks

I apologize for my pent-up eagerness resulting bad choice of presentation.

I wish i could replace the pictures with still pictures (and hope the undesirable gifs could be removed).


In any case let me always establish my highest regard for formZ 7 development.

I think that the sort of edge-caps of this geometry caused the problem.
Z helped me find my own answer. My solution is summarized as follows:

Remove the large Top Face

Remove edges (which i think are sort of object-caps).
There is an inherent problem with bending solids. The Rad Bend tool bends surfaces, individually, "as-is", without incorporating all the 'style' related issues of maintaining uniform thickness ranges, of a solid. These inherent issues are sort of outside geometry.

Scale to diamond layout. A geodesic styling of the T-Subz suits my need best. As my interest is in cost-efficient structure. (Not just visual styling).

The wanted volume calculation is simple for projecting material costs. These are easily calculated from surface area. In thin-shell construction which traditionally focussed on ferrocement. However, steel is increasingly being replaced with basalt-reinforcement products, (bars, meshes, fabrics).


Just one click, with default T-Subz settings, made this mesh.
Lovely.

Bo,

Great, glad this is allowing to do what you want! :-)
