“Algorithmic design is not simply the use of computer to design architecture and objects. Algorithms allow designers to overcome the limitations of traditional CAD software and 3D modelers, reaching a level of complexity and control which is beyond the human manual ability”.

AAD_Algorithms-Aided Design
* Parametric Strategies Using Grasshopper® * Grasshopper environment and plug-in software * Parametric modeling and advanced data management * NURBS curves and surfaces * Meshes and Subdivision Surfaces * Digital fabrication techniques Recursions * Form-finding strategies * Particle-spring systems * Topology Optimization * Evolutionary solvers * Environment-informed design

The key is exposure through out 2D drawing, 3d modeling, generative design & coding

Vector VS. raster graphics

Rhino + Grasshopper

Playing with rhino and grasshopper possibilities

Weaverbird Effect plugin just a trial To produce the point charge you can simply give the points to the point input and define the radius by using a “Gene pool” Be sure to double-click the gene pool and set the number of sliders same as the points.

Experimenting with pattern i would use on fabric for final project

step1: vector - grid -square grid

srep2: define a size using a number slider and connecting it to the size

step3: add another 2 number sliders and connect them to “extent Y” and “extent X”

step4: flatten cells (with right click on cells)

step5: define a point attractor … type in grasshopper “point”

step6: surface - free from - extrude point

step7: connect cells to base (in extrude point)

step8: surface - area tool (to extract the centroid) then write “move” (to move points up) and write “unit Z” and give it a number slider”

step9: vector- vector 2pt (take geometry from “move” and plug it in “vector 2pt” as point A ) not write/connect point on grasshopper and connect it in “vector 2pt” as point B

step10 : right click on unitize on “vector 2pt” - right click set Boolen - True (it means that the vector is one length- so just giving me a direction to the point attractor )

Autodesk Fusion 360

just truials tryina get familair with the Autodesk Fusion 360

tried with defining parameters

tryina with the array tool that i previously tried using autocad so wanted to see the difference is sitting the parameters

AutoCAD

here i was trying to create hexagonal grid for Wildcard week 17 to laser cut for wood textile but im an architect so i previously know how to use autocad! wasn’t parametric i just created hexagon and array to repeat it alone the rectangular boarder for the shelf i wanted to create or furniture piece which was 50*20 cm…

Inkscape

Here i wanted to test and compare the tracing of both Inkscape VS. Adobe Illustrator to transform from pixels to vectors (where makes you able to cut through CNC machines)

click on the image you want to trace, go to path, trace bitmap then a window would appear click the live preview to be able to see live while you play with settings to optimize the clearer desired trace and now move the traces image you would end up with a vector version of your picture and the pixel one remains as well

Adobe Illustrator

Choose Object > Image Trace > Make to trace with default parameters. Illustrator converts the image to black and white tracing result by default. Click the Image Trace button in the Control panel or the Properties panel, or select a preset from the Tracing Presets button.

Choose Window > Image Trace or switch to the Tracing workspace to open the Image Trace panel, and do one of the following: Choose one of the default presets by clicking the icons on top of the panel. For details, see Specify tracing options | Preset. Choose a preset from the Preset drop-down menu. Specify the tracing options. For details, see Specify tracing options. to sum up the the conclusion was that Inkscape showed more details of traced image and was better … thanks for coming to my TEDTALK hehe
