Here is an explanation I posted on Three.js forum.

My first post here; may I ask members what you think about marrying Three.js to Trail, Branch and Aspect interface?

Small Three.js sampler scene created from selections in TBA interface

Though small, this work in progress illustrates how a hierarchy of ideas, assembled with TBA selections, is made into empty Groups and Objects, and then expanded with selected 3D models and manipulations from bottom up. I have used Collada models, TBA identities and link tools, and custom design tools for margins, rotations, x-axis positioning, y and z axis alignment, footprint, and division elements; setting up for more manipulations like handing, grouping, cloning, layering, animation and so on.

The main point of my post is that this is a completely different approach, in this case to building design processes, based on selection rather than drafting. I am hoping those who appreciate that, will contribute to one or more of its multiple facets, to help push the experiment forward.

A long time ago I tried to promote something similar here. Now, I think there is greater awareness of the need for different ways of working since online productivity is more widely recognised. So I would like to re-introduce the idea of using models as the basis for such a new way of working.

As with Three.js, I am sure this forum's involvement will also help push the experiment forward.

Possibly a rivet joining to 2 clamps together.

Thanks for your input but my problem is really how to model a path that binds one tube to another at right angles when extruded as a tape or wire. Actually, I am thinking of trying plastic coated electrical wire as a durable and readily available material. It needs to have a waist to really tighten the binding; the salt-laden tropical winds can be really vicious.

Hi Chris, hi folks.

What do you intend to use for banding ?

Can you post a picture or is it like shown with dry vegetal fibres (bamboo ?).

This is a better picture

It is very strong; sold in 600mm lengths. Not sure I can get in Sri Lanka, but other material will look similar.

Hi Chris, hi folks.

See this SU file for ideas.

Thanks Jean,

I am trying to show how the finished joint will look ... there are many ... a neater version of this type of thing.

The pipe runs are on a roof that is on the shore of the Indian Ocean, so I am proposing using PVC pipes for the gantries and some kind of PE banding to bind the existing PVC water pipes to replace this mess:

So I need to present the final new look to compare.

The installer creates a band like you have modelled but with a waist both to tighten and tie off the banding (hence figure of eight).

I tried but found that too much for me ... that is why I am back here!

Cheers

On the ear'ol again I am afraid.

I am looking for a model of a figure of eight with the top loop 90 degrees to the bottom. It is to strap two 25mm pipes that cross each other together.

Ah yes I remember them ... But here in Sri Lanka we can trip the light fantastic with homegrown teak and a wish and a prayer. Public liability insurance ... what ho!

With people, water tank and Triffid

My two bobs worth: I would bring the brackets by the double opening as close together as possible, the span at present seems too wide. And possibly add another.

Thanks, I am just providing the concept and major components; another guy is creating the model from the cad drawings. An engineer will be involved. But your comments are noted as they say around these parts.

@baz said:

I would beef up the right angle corners of the brackets as well, there will be a large amount of lateral force on that joint.

Noted.

The access stairs worry me, are they removable? I wouldn't like to see a party up there

They are just for maintenance staff and Triffid pruner. It will have a hatch at the top. It is next to a small pool, so it is also a kind of drinks stand, clothes horse, poolside thing.Thinks, maybe extend some treads though the vertical trellis.
