Computer-aided design (CAD) is the use of computer programs to create graphical representations of physical objects in two or three dimensions (2D or 3D). CAD software can be specialized for specific applications. CAD is widely used in computer animation and in special effects in films, advertising, and other applications where graphic design itself is the end product. CAD is also used to design physical products in a wide range of industries, where the software performs the calculations to determine the optimal shape and size for a variety of industrial design products and applications.
_Workflow /Step by Step
_Evaluate and select 2D and 3D tools.
During this week we worked on different tutorials that were a great help to first know the design tools and then (the one that seems better) to work with her to prove with which we better suit. These are some of the tutorials that I attended at the fablab this week:
I already knew some 2D and 3D tools but not with parametric design, so the one that interested me was Grasshopper but I need to understand it more deeply so I started to model some pieces with Rhinoceros that I know a little more so then switch to Grasshopper.
_Final project modeling.
After all the tutorials, I focused my assignment in Rhinocers+Grasshopper for trying to modeling parametrically. In order to having all the pieces that I need to conect all the tangle, I've made 4 different each one have with an output that will work when the tangle get closed.
To begin the modeling of each piece, I started to build the basic form in Rhinoceros following the next steps:
With the make2D command I made some croquis to understand each module.
Later, I hope to begin building the forms and connections between them using Grasshopper once the conception of form is understood; the parametrical design will help me to change the dimensions proposed in this first exercise so that I can change them while I work more in depth on the final project, taking into account other factors such as the materials to be used, the size of the electronic boards that will take in for example.
