2. Computer Aided design¶
This week I started to know about different designing software 2D and 3D.
Cuttlexyz¶
A vector editor with features for cut design like live modifiers, parameters, reusable components, and scripting. It’s a nice and easy tool to make 2D designs and it is available online without downloading it.
here is a random design I made it using it.
-
First I started with simple circle
-
and did rotational repeat on it by clicking on modify
-
after that I made a new square component and I drag to the first one
-
In this step I did another rotational repeat to the square also
-
And now I select all of the component and do Boolean difference on them
-
Now I can change the first component using the second one so easily and that will help to do fit parametric designs in the future
inkscape¶
Inkscape is a free and open-source vector graphics editor used to create vector images, primarily in Scalable Vector Graphics (SVG) format. Other formats can be imported and exported.

Here my try to use the software to make a hidden blade.
-
first I made a simple rectangle.
-
I put a blade using this tool you see here.
-
Now I used the fill and stroke tool to color the design
-
I added some component here using the same tool above and finished the design
Inkscape it’s a wonderful tool to edit 2D designs and make texts design for cutting, molding, engraving, etc. in my opinion it will be a very useful tool in the future.
Opencscad¶
OpenSCAD is software for creating solid 3D CAD models. It is free software and available for Linux/UNIX, Windows and Mac OS X. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects.
Thus it good and fun tool to use to make 3D model. Here is some valuable link for beginners
- Documentation
- cheat sheet
And here I tried some of the function from the cheatsheet:
- I started with a simple cylinder.
- Now I add a for loop and translate function that the Y axis depend on the i in the for loop.
- I added here a cube and did the same thing and also a sphere but without translate or a loop so there is only 1 sphere here.
- final step I rendered the design and export as svg.

this is the code
// openscad
for(i =[10:10:100]){
translate([10,i,0])
cylinder(r1=10,r2=10,h=10);
translate([0,i-10,10])
cube(10);}
sphere(10);
Fusion 360¶
Fusion 360 it’s cloud based 3D designing software. In my opinion it was hard for me to get to it at the beginning but I am sure it will be very powerful tool when I get used to design on it.

Starting Tips
Here I tried to make a Hollow cylinder and small one inside it -
I started with sketching in fusion by drawing a circle
-
Now I use the offset tool to make a separate circle inside it.
-
After that I finshed the sketch and did extrude for the outer and inner circle so I had to cylinder here but with different height.
-
Here how it look from above.
-
And finally I exported the sketch.
