Exercise - CAD

Digital Models under construction

This week assignment is about design with software and hardware available. We had a list of options to choose. I took InkScape and SolidWorks to run its tutorials and learn. The cad software I daily use would be Fusion360. These three software are the set I worked with.

The task asked is:

- Model (draw, render, animate, simulate, ...) a possible final project, and post it on your class page with original 2D and 3D files.

Class material: Computer-Aided Design

Inicial notes on this topic:

Definition and Wikipedia's info on CAD (Computer-aided design) is a good introduction to this topic. As I have already been working with CAD technology for a few years, it is not a new thing for me. Even thoght, almost every month someone shows up with a different plugin or addin to a software. New features are happening constantly. It is nice to pay some attention to this updates. But, the basic design strategies (or how to thing a solid body) haven't change for me. I learned different tools this week and hope to keep on learning always.

Files related to this week assignment will be found in this GoogleDrive folder.

First Model - Solidworks

I ran the first tutorial of Solid Works. It was a good trial. The draw tool is really impressive. But, I would like to point that the tutorial for a first approach is well done. I could, without having any contact with a later SolidWorks version, make easely. I recomend anyone that wants to start working with to run its tutorials. The files related to it are here01 and here02.

Tutorial one. It follows the design of a piece in 3D and its 2D related scketch (2D view ports from a 3D model). The step-by-step procedure was available from SolidWork's own menu options.

Modeling with InkScape

The Insper Fab Lab team work with InkScape since the beggining. It is a freeware tool for design tha fits to prepaire laser cut files and vinyl cut files (among other applications). It wasn't that easy for me at first to work with this software. To choose runing one of its own tutorial suggestions - and I started with Basic - was wise. I learn that simple comands, after you get the short-cut knowledge, can be very annoying if you miss where to look for them. The InkScape tutorial was a colorfull experience of learning.

InkScape website. As you can see, the 'home' page is easy to navigate and find download menu and lear menu options.

Release 0.92.2 is the one I had installed in my computer. I had to change my notebook three times during FabAcademy (Please, never do that!!!), so I wanna keep track of this software version.

This was just an exercise of InkScape commands and freestyling creation. It also comes in pdf file.

This is a design for a desk organizer. We have some of those helping us managing machinery tools. This one is design to be available to milling machines Roland SCR-20. You will find this file here.

If you need to export the file as pdf make sure to follow this image setup. Otherwise, there might be some file errors. In order to make it with an EpiLog Mini laser cut machine (available in our Fab Lab), I chose to have a copy as pdf format file.

Modeling in Fusion 360

To model with Fusion360 is more like a daily job for me. The final project and most of other modeling activities are gonna be developed with this software. What I learn during this assignment with Fuison360 was the rendering tool. It has a feature on cloud that renders the image and let it available to the user's computer after finishing its processing. To render an image is attribute to a solid body characteristics of our phisical world and wait till the computer translate it into a realistic image (when it works properly).

As Fusion360 is on cloud, to share the project with others I may send - by e-mail - and invitation to it (project's folder online). My personal contacts will be found here. To have this project standard file, please click here.
