Designing the components

The design of the components is constrained by the manufacturing process, namely a CNC cutting

machine, and so their shape is based on the interlocking of vertical and horizontal planes.

A forma dos componentes limitada pelo processo de fabrico, ou seja, por uma

mquina de corte CNC, deste modo a sua forma baseada na interligao por encaixe

de planos verticais e horizontais.

Future improvements

To apply the system to a real design context other features should be considered as well:

1. ground topographic variations.

2. adapt the morphology of the structural units to the roof.

3. develop feasible connections among roof parts, and between the roof and structural units.

4. analyze the structural performance for optimal configurations

5. automate the given tolerances of the interlocking parts to other CNC technologies, such aswater-jet cutting machines

Futuras melhorias

Para aplicar o sistema num contexto real de projecto, outros aspectos devero ser considerados:

1. Variaes topogrficas

2. Adaptar a morfologia das unidades estrututrais cobertura3. Desenvolver ligaes execuiveis entre os componentes da cobertura e as estruturas

4. Introduzir a anlise da performance estrutural de modo a optimizar as solues

5. Automatizar a entrada de tolerncias para os encaixes conforme a tecnologia de fabrico adoptada.
