PARAMETRIC DESIGN
The parametric design is an advanced technique of digital design that allows to introduce a series of variables or parameters, such as spatial limits, volumes or temperatures, in a specialized software (Rhinoceros and its Grasshopper plug-in is the most used) to manipulate them using algorithms and to obtain geometric designs more complex, versatile and original.
In Inkscape software I design the decorative piece, from precolombian motives. I cut in laser and probed some forms.
PARAMETRIC DESIGN AUTOCAD
Save as InkScape file in .dxf file. Open it in AutoCAD.
In Parametric menu, You can use Geometric or Dimensional Parametrics.
Use restrictions (linear, horizintal, vertical, coincident, colinear, etc, for parts that no changes. You can change names and you can use algebra parameters.
You can use Autoconstrain tool to assign a number of constraints in one pass.
You can use restriction for one object and other can be kept the same size.
If you use parametric Dimensional, the sizes keeps constant
Another form to changes parameters is by Parameters Manager. Inside, you can modify value of Dimensional Parametrics

RHINO & GRASSHOOPER
Grasshopper® is a graphical algorithm editor tightly integrated with Rhino’s 3-D modeling tools. To install Grasshooper in Rhino, Download from webpage and execute it.
An algorithm is an effective method that can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input. (wikipedia)
After install, you can use Grasshooper writing it name in Comand line.
For to understand Parametric funcion, We do an excersise.
In menu Standard, create dots with single/Multiple pointstool
Create a new file in Grasshooper
Import the points to Grasshooper
1. Double click in workspace
2. Write points and select Point
3. Create component
4. Click right button in component and select Set Multiple Points option
5. Select the points (its turn green/red if select/deselect component)
We turn points in to circle
1. Create new component (double click right button)
2. Wtite Circle and select Circle CNR option
3. Create component
4. Drag and drop the poin component to Circle component and you can see circles in Rhino points.
Other way to turn points in circles is create in Rhino circles and copy in points. It is very easy if it is few points, but if the pointas are thousands?. With Grasshooper, it is easy.
1. Create new component (double click right button)
2. Wtite Number Slider and select it this option
3. Create component
4. Drag and drop the poin component to R Circle points
5. If you slide component, circle size will change
6. You can edit propieties writing click right button in component
7. In Numeric domain and Numeric value you can change size
This changes are only in Grasshooper. If you "baker" in Rhinno, do this:
1. Cick right button on Circle component and select Bake option and click OK
2. Select any circle in Rhino and move it.
PARAMETRIC COLUMN
1. Create a component call Cylinder in Grasshooper (BRL - Base, Radius and Lenght)
R part
Number slider component and conect with Cyl component in "Radius"
CONCLUTIONS
Designing a process and not a concrete result: In designing a process we develop a collection of mathematical and geometric relationships creating processes and systems (algorithms), which allow us to explore more than one result.
Possibility of relating variables / parameters: Having a design process and not a pre-established form can be manipulated variables and properties, which we can modify in real time and thus compare results, in order to have a more efficient result.
the design can be adapted to any parameter / variable that is integrated into the design process, giving an intelligent and responsive result that satisfies a specific problem.
One of the major advantages of parametric design is the symbiosis between disciplines, which allows us to integrate structural, social, flow simulations, etc. In order that the three-dimensional model is not only a virtual model but a tool capable of giving us results and information to achieve more grounded designs that offer strong r
VINYL/ADHESIVE CUTTER
CAMEO Silhouette is a small plotter, it's can used for many things that we need. CAMEO use silhouette-studio software for it's cutter, you can download here

You can write a text and format it, text style, size, justification, caracter and line spacing.
OBJECTS AND COLOR
You can design many object with simple form.
BOXES AND COMPLEX DESIGNS
SHEET ADHESIVE CUTTER
I set adhesive Sheet:
1. Material Type: Adhesive-Backed Cardstock
2. Blade Type: 4 (physically too)
3. Speed: 2cm/s
4. Tickness: 20
CONCLUSIONS
1. Using a simple piece, you can build a system or structure of large dimensions.
2. Some machines could be built using mechanical parts (wood or acrylic ) created in a laser cutter.
3. In Fablab Yachay, I saw structures in CNC machines that use acrylic material cut with laser.
