This is vector worx

computer-aided design
Here's our assignment:

x model (raster, vector, 2D, 3D, render, animate, simulate, ...) a possible final project, and post it on your class page




When I last started my FabAcademy in 2015, I had a fair knowledge of 2D / 3D design and played with Antimony, Sketchup (my favorite tool at that point), Rihno for mac and Flood Editor (which I find very interesting). I have experience with OpenScad which I use as much as I can when I need simple things. Now I rarely use OpenSCAD if I need filets mostly because there is in my view much simpler ways to do so.
A note on SolidWorks and why you will not find anything done on SW. It's a super powerfull tool. Much like a ICBM when trying to hunt a turkey. I do not need stress test. I do not need to spend 10K$ on a licence. I dont want people at the lab to crack a software. So no SW for me... I fundamentaly think that Fab Lab software your be simple and as cheap as possible (accessible) just like labs so users can work at home and make at the lab. My two cents
Ok so this time arround, I decided to play with Fusion360 because we have free licences and I was amazed how efficient it is. I also played more with Flood Editor, with Inkscape to prepare a project for Week 3 beacause at the time writing this, I'm a week behind. And I also worked with NodeBox. Let's dive in!
Starting with Inkscake, I merged two shapes to make the body of my piece of work My goal is to make a jig for making paper lanterns. So converted my two shapes to path and joined them using Union At the moment, there is no filling, just a 0.1mm path. Once joined, I remove what I do not need.
Now I need to have concave slots where the wire is placed on the jig. To do so I will create a pattern along the path using the dialog of the same name. But after trying and following a nicely written tutorial, it failled big time. Instead of pursuing that direction, I decided to use the Create Tile Clone function. A tutorial can be find here> So if you need to create a radial tile, you need to use theses settings ( I need 60 notches, so 60 circles.) Here's a tutorial video for radial patterns
So now that I have an array of circles on my path, I combine the two using Difference function, and having the path in the back. I end up with 60 perfectly alligned notches. Yé! Here, I'm making the press-fit connector that will connect my 8 part jig. This is adjusted to my material size, so 0.435mm. I'm placing all my parts together and optimizing space for the material. Job's done. Actually It took most of a mornig to work on that project. I'm fairly experienced with Inkscape but because I repeat the same operations weekly, I'm still relying on tutorials to understand functions.

I will now briefly explore 3D desing with FloodEditor and Autodesk 360. I'm in the middle of rethinking my final project so I have no interest in trying to model that specific project. All modeling regardint the Final project will be hosted on the same page to prevent further confusion. The goal here is to explore two software. Flood Editor is a fun. Autodesk is intuitive. NodeBox is similar to Processing but quite easy to play with.

What I like about FloodEditor is its nodal editor. Similar to Graphscad and NodeBox. As they pretty much all use the same interface, just like Antimony, it's easy but sometime confusing to go from one to the other. Nodebox allow the user to export a SVG. FloodEditor do the same with a .STL. Great! I mean there's so many options at the moment on the software market that it's almost impossible for me to choose. My graphic card is quite old so I can't drive the latest software. I already ranted about SolidWorks.
So two years ago when I tried Autodesk Fusion 360, it crashed quite often, was NOT intuitive and I hated the Cloud based approach. Now I'm in love with that software. I can do in 1 hour what took me 3 hours on Sketchup! I can import parts from my big yellow McMaster Carr catalog! Only downfall, I need a new computer as my laptop is too
This is a standard render in FloodEdior. The interfaced changed a bit. There's new nodes. Seriously, juste hit the site and try it. There's now installation as it is web based. Now you can appreciate the texturization of the sphere by looking at the parameters changed in my nodes. I want to talk for a second about BlocScad an other spinoff of OpenSCAD, this editor is also web-based and use a jigsaw puzzle approach to 3D desing. It's cool for teaching kids. Easy to edit the nodes. Sometime less confusing than OpenScad and the interface is quite nice for kiddos. There's an interesting article here about parametric nodal editors.
Let's have a look at the Fusion 360 Workflow. The goal is to make a coaster for an industrial racking. I start with a 2D sketch of the outline of my rack leg. Using the Create / Extrude function, I extrude my shape by 100mm, simply entering the value or pulling the handle I added the coaster of 4mm to my part
Correcting the first extrusion by using the Modify / Extrude function - 3mm Here' my sketching my holes pattern directly on the surface where I want theses holes to be. Their purpose is to save on plastic while keeping the structural integrity of the part. Using the Create / Extrude I create the holes -6.0mm
Voila, I can export the STL by using the Make button. I tried the render function. Up to now, my favorite renderers are with Blender and with Rhino. Now I do not own a license of Rhino ( I only used the Mac Beta. ) so I would normaly go for blender. But I was quite pleased by the Fusion renderer....untill it crash several times. As I said previously, my macbook has a lousy graphic card. I just ordered a new computer in the hope that it will ease my work in the future. So just a quick word on NodeBox 'cause I briefly talked about it... It's a software similar to Processing. Great for graphic art. I spend an evening playing with parametric functions in order to learn to make something pretty. It used the nodal functions to change variables. You can get the skech in the asset files.
