Group 4 Presentation “Celtic Knot”

2-CIty_Hall_Plaza

Group 4 presents the Celtic Knot, an iconic structure that can fit everywhere and will function as a meeting spot as well as providing shade.

It is based, just like the celtic knot, on three repeating patterns, which makes it easy to produce. The design is a combination of a bench and an arch, which connects to the second bench and arch.

The arch and bench itself can be cut into four parts, which each have an inner and outer panel, so only eight molds are needed for the total design, which all will be reused three times.

The complete presentation can be found here.

Minimum bounding box

For creating the molds, it is very useful to find the minimum bounding box for each surface. Grasshopper can use iterative evolutionary models to find the best fitness for a group of parameters (genes).  This method is called Galapagos.

So instead of trying to find a good bounding box, we input the bounding box pivot points axes as genes and use the resulting volume as a minimum fitness.

In the end you can automatically calculate the mold area you’re using or check the max height requirements.

TODO: Work on extruding to make the actual mold, instead of only the bounding box.

The result with one our of models:

2013_Q3

After a Week we’re getting somewhere

We worked this week together and individual (because a mouse can only be controlled by one)

The idea of Maarten got our attention: the Celtic Not, due to its point-symmetry the object can become larger.

A design Georges made incorporated the Not, 20140221_114436

A Design by Yi-Chien gave another perspective:

0221-d

We are now trying to make a connection between the two designs:

A twisted knot:

001 Twist start

(the one with a 60 degree coverage / 360 degrees)

002 Twist 60 degrees

With addition of a bench to give the shape a function

004 Total form

And the tree’s made:

0221-2

We going to further develop a structure bases on a combination, a kind of forest twisting and curving around a centerpoint.

Inspiration from Celtic knots and similar forms. Their point symmetry helps with multiple panels from one mold.

overview

Though the model is a bit bland, the group decided to use at least some point symmetry for a support structure and then use the rest of the mold for a free form surrounding it. This is just my interpretation of it.

The next step is to check the possibilities of actually making molds for our model using bounding boxes in Grasshopper. The idea of using the same molds multiple times/same panels:

Tomorrow we choose our group design and improve it further.

Could we make two slender panels next to each other in one big mold? #spacesparingmoldtechniques
