ugh information (whether coming from environmental analysis or any kind of database), extracting and managing informations for construction processes all require an understanding of data structures in order to build seamless design-to-construction pipelines. Through visual scripting in Grasshopper (Generative modeling plug-in for Rhinoceros) participants will learn how to build and develop parametric data structures (from basic simple lists to complex data trees), data-driven geometry and envelopes and how to extract relevant informations from such models for construction processes. Participants will also develop a personal envelope project and its full design-to-construction pipeline.

ne diverse digital design methodologies and the use of different tools such as Autodesk Maya, Rhinoceros and Grasshopper.
Building up technical skills will provide the attendees with a solid platform from which to start rethinking and exploring innovative architectural ideas in collaboration with the team and the tutors.
URBAN FIELDS
Phase I
In the first part of the workshop attendees will be looking at field conditions and how to generate and design such fields that can help structure a possible urban condition in Florence.
We will be exploring dynamic systems, geometric systems and network theories to generate and design an abstract field condi- tion that extends the urban experience of the city onto the vertical dimensions of towers. Simple operations that would span variations from an initial state will give rise to high level of com- plexity.
The goal of this exercise is to create a rich and diversified intel- ligible urban space that can be later on subjected to local inter- ventions and zooming in to locally enhance each design.
AGENT - BODIES POLYMORPHISM
Phase II
The second part of the workshop will build upon first phase; par- ticipants will select one archetype (high rise tower) as a study model for further development.
Besides engaging with multi agent algorithms design strategies, attendees will address strategic utilisation of structurally and environmentally generated morphologies to design coherent and highly differentiated tower exo-skeletons.
Tutors will introduce agent-bodies polymorphism in order to explore the generation of structural aware and capable geom- etries through agent based formation of non-linear hierarchies and emergent patterns. These agent-bodies will operate in a complex spatial manner to form structure, partitions or enclo- sure and will operate across scales, creating a poly-scalar level of detail.
Attendees will speculate how autonomous systems can cre- ate new structures and intelligent distribution of structural elements, about new collaborative strategies of construction and the performativity they will evoke (performance, effects, responsiveness, interaction).

both my plotter/cutter and wide format printer. I had been running the plotter from my main work laptop - a Win10 machine via the plotters USB port. As it turns out you can't get Win XP drivers for this USB connection so I needed another solution.
I tried to use the plotters DB25 serial port connection using an old DB9 to DB25 modem cable I had in my collection = no luck the plotter wouldn't talk. A bit more research and it turns out these plotters need a 'null modem' cross over cable to operate. I found a pic of the correct wiring online and made up my own with some cable and connectors from the local electronics hobby shop.
With this hooked up and using Hyperterminal I was able to fire some codes to the plotter directly and get a response back - winning!
At this point I got my original code working with the 'net use' redirect from LPT1 to COM1.
HOWEVER - being that the plotter was now on a COM port there are a few more interesting things you can do with it - one is being able to read the paper size/cut area from the printer.
So what I needed to to was find a way to send and receive data to/from the plotter using the serial port.
A bit of research into .NET's serial port interface and using a bunch of small pieces of test code I have manged to completely re-jig this driver.
Upgrades include:
- Direct Serial Port comms using Null Modem cable (a USB to serial adaptor + null modem should also work)
- Plot area read from the plotter - a rectangle the size of the plot area is placed on a separate layer and coloured red
- Testing to see if selected plotting curves are both closed and inside of the cutting area - with errors shown and exiting if they are not right.
- After plot 'parking' of the plot head at the end of the cut items + an adjustable offset (currently requires manual resetting of origin on the plotter before for next cut)
Great thing is it is now 100% running within Rhino Python - no DOS command line calls = no flashing up of the CMD wind. Also no temp files needed on the HDD and no limit to number of curves that can be plotted - tested with 200 or so with no issues.
Overall very happy with whole project - have learnt a LOT about Python and .NET interfacing AND ended up with a very handy/useful tool.
Cheers

ariations, but each seems to lack the sophistication to generate a ‘zip’ that retains its general shape over the whole curve.
Basically I’m trying to understand the process behind this: http://www.schindlersalmeron.com/index.php?option=com_content&task=view&id=27&Itemid=29
Here is an image of the latest definition.
1. I draw a curve in Rhino, and then define it in grasshopper. I also define the point as the beginning of the curve.
2. I offset the curve to a specified depth, based on structural member
3. I generate a line from the point at a tangent to the curve, then rotate it a
defined angle.
4. I find the intersection between the rotated line and the offset curve. Then generate a tangential line from this new point
5. Line is rotated at the same angle as before.
6. Process repeated.
The idea is to then generate a circle of defined diameter at each of the intersection points, then find the intersection of the circles with the curves, which are then joined up with straight lines to create the ‘zip’. This would mean a lot of copy-pasting and list management that I’m not really capable of with my limited grasshopper experience.
I had tried generating points at intervals along the curve and then eventually generating lines from one line to another with a shifted listed to form the tooth angle, but it wouldn’t retain its shape over the entirety of the curve.
Does anyone have any advice for how to tighten up this definition? I imagine that I will need to delve into vb.net scripting to address the recursive nature of the process.
I fear that I’m going about this in entirely the wrong way...
Of course the next step is to flatten out the curve for CNC manufacture.
Any help would be greatly appreciated! The potential for using grasshopper in design is amazing, and I would love to gain a deeper understanding of it!…
complicated than it seems as I have an event and a subscriber method receiving data from a serial port.
In the code below, the strings received within myReceivedLines appear when connecting with the serial port (when connecttodevice is true). However they disapear when I launch another command (when homeallis true).
As you recommended in your reply, I have added the field called myReceivedLineswithin the class so that I could use the method String.Add() to all the feedback received and commands sent.
Why does the feedback dispear when a command is sent? Is the string going to myReceivedLine disappearing because they happen within a subscriber method or is it related to the DA.SetDataList() method used to assign myReceivedLinesto the output?
Many thanks!
