# 4. Computer controlled cutting
This week I worked on:
- Going deeper into Autodesk Fusion 360
- Creating a 3D Cube model
- Lasercutting a 3D model with Finger Joints
- Lasercutting Build Press Kit
This is was an intense week but, a very rewarding and knowledgeable week. I visited the Dassault lab in Boston, MA to work on the 3D Model using AutoDesk Fusion 360. Learning Fusion 360 came with a steep learning curve and applying Fusion 360 for laser cutting purposes didn't help with the steepness. However, as mentioned in the previous week, LinkedIn Learning and seeking guidance from my group allowed me to pick up the necessarily skills to create a 3D model with finger joints.
- Designed a parametric press-fit construction kit
- Lasercut a parametric press-fit construction kit
- Cutting using a vinylcutter
- Group Assignment
On top of seeking helping and using LinkedInLearning, I had to do furhter research on creating finger joints. Some resources I found were:
## Designed a parametric press-fit construction kit
This week, I worked on creating a parametric press-fit construction kit. The kit was a two cubes that can be taken apart and assembled in multiple ways. To be able to do so, my design was using finger joints. Finger joints, also known as a comb joint, is a woodworking joint made by cutting a set of complementary, interlocking profiles in two pieces of wood.
To design a finger-joint design, I used the following resources below:
1. [Fusion 360: Automatically sized finger-joints](https://www.youtube.com/watch?v=9U2JPfkQpsE)
2. [Designing Laser cut joinery in Fusion 360](https://www.youtube.com/watch?v=HKcgTsXM4h4)
3. [Use Fusion 360 CAD Software for Laser cutting](https://www.sculpteo.com/en/3d-learning-hub/laser-cutting/fusion-360-cad-for-laser-cutting/)
## Going Deeper into AutoDesk Fusion 360
The above reesources and help mentioned allowed me to explore Fusion 360 more in-depth. I was able to add a plugin that would help make the laser cutting process easier. The plugin was called **DXF for Laser** and it is located in the Fusion App Store. This plugin will generate a Kerf (laser cut width) compensated DXF file to produce laser cut parts with dimensions that match my drawing geometry. In other words, this plugin allowed me to export my sketch into DXF and to take the Kerf into account at the same time.
Since the goal was to lasercut my design, one of the resources I used mentioned to search for a plugin on Fusion 360 called **DXF for Laser**. This plugin can be found in the Fusion 360 app store. This plugin will generate a Kerf (laser cut width) compensated DXF file to produce laser cut parts with dimensions that match my drawing geometry. In other words, this plugin allowed me to export my sketch into DXF and to take the Kerf into account at the same time.

## Creating a 3D Cube model
This was an exciting journey. It started off frustrating for many reason but the primary reason was because I was at a lost using Fusion 360 to create a finger jointed cube. Though I was able to find resources on doing finger-jointed squares and rectangles, the resources I found were either advance or were a bit outdated as many of the videos used a verison of Fusion 360 that I did not have.
Unfortunately, the resources I used were complex. I decided to request help from my instructor, [Spencer Mewherter](http://fabacademy.org/2020/labs/dassault/students/spencer-mewherter/), a Fablab alumnus and the Boston team's instructor. Spencer was able to provide me with one-on-one guidance on using Fusion 360 to create a finger-joint cube. We started off with adding some parameters thus making my design parametric.

So, I sought help from my instructor, [Spencer Mewherter](http://fabacademy.org/2020/labs/dassault/students/spencer-mewherter/), a Fablab alumni and the Boston team's instructor. Before I continue, I definitely want to say thank you Spencer for your help!
It is good practice to make my design parameteric in the case that I would like to change the size of my cube. The next step was to start a new sketch on the top orientation and create a square:

![Square](../images/week04/square.png)
[Parameters](../images/week04/parameters.png)
From there, I made some cuts and extruded my square:
Creating parameters allowed me to reuse the values I created throughout the model. I found this an efficient approach as it saved time from changing each sides.
![Square_Cutout](../images/week04/square_cutout.png)
After I created my parameters, I started with a sketch of a square on the Top of the panel.
Once I create my base, I repeated the process to create more fits/pieces so that it can represent a cube:
[Square](../images/week04/square.png)
![repeat](../images/week04/repeat.png)
This square was my foundation as it lead way to turn this square into a 3D model with some cutouts on the sides.
My repetitive process lead way to the following:
[Square_Cutout](../images/week04/square_cutout.png)
![final](../images/week04/final.png)
After I created my first side, the process became repetitive. I chose a side, duplicated my foundation sketch, and matched the duplicated sketch with my original sketch.
## Lasercut a parametric press-fit construction kit
Lasercutting my design requires me to export my design into a DXF file. There are **two** ways to do this. One way is to use a plugin. The pluggin I mentioned earlier called [DXF for Laser](https://apps.autodesk.com/FUSION/en/Detail/Index?id=7634902334100976871&os=Win64&appLang=en). Another way is to create a *DXF* from your objects within Fusion and exporting those objects onto the lasercutting machine.
[repeat](../images/week04/repeat.png)
Though I downloaded the pluggin that would do the work for me, I decided to discuss the process needed to export to dxf without the pluggin. The first thing to do is to copy all the pieces and leave the original where they are. The copies will be the one I will be working with. The goal with the copies is to lay all the parts out so that they are flat on the Fusion plain so that I can export or create a drawing of all of the faces in the next board that is a DXF. Once everything is align on the same plain, select a face and start a new sketch on that face.
After a while, I started to get the hang of the process and before I knew it, I created my 3D Cube.
![capture_face](../images/week04/capture_face.png)
[final](../images/week04/final.png)
From there, you select the face, right-click, and choose to *Project*. From there, select all the other faces. So, by clicking project and all of the other faces, you will have everthing included. You will now have a new sketch that will have the faces you selected. From there, export the sketch as a **DXF** file, save it, and open it in Adobe Illustrator, or a similar application. If you need further guidance, you can watch the following resource: [Laser cut octopus lamp](https://www.youtube.com/watch?v=vBpBJdXZF4s).
## Prior To The Laser Cutter
To lasercut the cube, I needed to export my design into a DXF file. As mentioned, I added a pluggin that allowed me to do so.
Since I used the pluggin:

![plugin](../images/week04/plugin.png)
But, before I exported the file, Spencer suggested I check to identify if there are any `Interference` in my design. Checking for `Interference` can save you a lot of trouble when laser cutting the model.
I did not need to do the steps to convert into a DXF file. However, before I exported the file, my instructor did advise me to identify if there are any `Interference` in my design. Checking for `Interference` can save you a lot of trouble when laser cutting the model.
[interference](../images/week04/interference.png)
![interference](../images/week04/interference.png)
I had a few interference within my design. The simple approach to fix those interference was to cut some sides to ensure that my model can fit together and no side was intervening or prevent a snugged fit.

Once my laser-cutting was done, I decided to explore the idea of creating a press kit with some documentation, in the case someone wants to implement the Laser Printed Cube.
After watching/reading some tutorials on how to do so:

The procress to create a kit wasn't too difficult.
1. I broke up my pieces, to separate them, so I can transfer them into the press kit.
2. I went to my design and selected File -> New Drawing -> From Design
