The subject


Architecture decays; start of a regular project THE CAUSE


Generating logic


Forming of architecture; the “hatstand”


Further justification of the “hatstand”

Some magic words for the presentation:
open / gesloten
natuurlijke, onbewerkte en duurzame materialen
t lijk b kt d t i l
strak
eigentijds
contrast


The acceptable but generic result

Et voila!


The side-effect of our dynamic society

“..not the analysis and assessment of
the future, and the transcription to architecture are
important, but rather the control during the unpredictable
i t t b t th th t l d i th di t bl
various developments of the future.”


“THE” question to me

“Would it not be better if our built environment admits and
physically displays the dynamics of our society?”


Our current situation


My proposition


Dynamic? Physically!


The research question

“How should the structure of a dynamic building look like
How should the structure of a dynamic building look like
and what intelligent behavior should it display?”
1. What kind of shape does one element of the system need?
f p f y
2. What kind of material can be used?
3. What types of intelligent behavior are a necessity, what desirable and what redundant?
4. Is it desirable to build dynamically in the future?


The final products


Break

Experiences

CA(A)D
AND
CAM?


C(AD)&C(AM)

CAAD! CAM!


The altered process
The effect of CAAD & CAM
..different tools, possible different results
..different tools, certainly different process

Value? (e.g.)
‐Higher efficiency
‐Higher efficiency
‐ Smaller amount of errors
‐ Increased production speed
‐... and more
d


The altered process

At the start of any CAAD and / or CAM process..

“Bezint, eer ge begint”
..contemplate before commencing!

What final products do I need to produce in what form?


The altered process

In case of the graduation project
“Prototype of a static dynamic building”

Report (booklet)
g
Planning
Technical drawings
3D visualisations
3D models
3D models
Scale model
The prototype
The actuators
The act ators
The software & sensors

.. and more



How can CAAD and CAM add value to my process and
products?

Using CAD for the report I have
Using CAD for the report I have
the ability to..
‐ Produce the report faster
‐ Reproduce fast
Reproduce fast
‐ Adjust easily
‐ Share
‐ Pi t
Print professionally
f i ll
‐ Check my spelling(!)
‐ ..



What kind of software packages are meant for this task?
p g

Where in the process do I need to use these?


Make a first selection of packages, 2 to 3, for EACH product
M k fi l i f k 2 3 f EACH d
and then evaluate further;
‐Exchangeability
‐Your own knowhow of the packages
‐Position in the process

Research finished?
R h fi i h d?
Packages chosen?
Simulate the COMPLETE process..

..and if necessary change a chosen package.

Conclusions


Conclusions

Preliminary research is a do!
P li i hi d !

Starting immediatly with a package a don’t..


Conclusions

The right tool for the job..
Th i h lf h j b

..saves effort and improves the result.


Conclusions

The larger the toolkit..
Th l h lki

..the better and more specific the result.


Conclusions

Perfect matches are impossible..
P f h i ibl

.. not one package is able to do it all.

(or, improper use is inevitable)


Conclusions

But stick with the right tool.
g

Don’t use Sketchup for final presentation renders..
(3D s Max!)
(3D’s Max!)
.. but for quick sketchy 3D mock‐ups.

Don t use Photoshop for rendering lay‐outs or posters..
Don’t use Photoshop for rendering lay outs or posters
(Indesign!)
..but for editing pictures.


Conclusions

Don’t confuse design decisions for modelling decisions..
D ’ f d i d ii f d lli d i i

..they will eventually lead to design consessions.

In other words, CAAD and CAM are means (tools) and not
an ..


Conclusions

..end.
