# openscad IDT creation scripts

these are a collection of scripts and layout for creating IDTs within openscad as well as some fun
layout on wafers. Currently these scripts only support bidirectional IDT but i will be adding more
in the future. but you could create cool IDT on wafers like this:

## to start

- download openscad
```bash
$ sudo apt install openscad
```
- clone this repo
```bash
$ git clone https://git.sirlilpanda.studio/sirlilpanda/openscad_parameteric_IDT_creation_scripts.git
```
- create a new openscad file within wafer layouts for this example it will be called `your_new_idt_layout.scad`
```
...
|
├ wafer_layouts
|    ├ cross_pattern_idt.scad
|    ├ hex_layout_idt.scad
|    ├ pair_idt.scad
|    ├ quadrant_array.scad
|    ├ your_new_idt_layout.scad
|    └ single_idt.scad
├ common_params.scad
└ README.md
```
- add the required files to get started in your `your_new_idt_layout.scad`
``` scad
// > your_new_idt_layout.scad
// the idt module itself 
include <../modules/bidirectional_idt.scad>

// a module for nicely displaying the parameters used for your idt
include <../modules/parameter_text.scad>

// a simple wafer model that wont get added in to your final design
include <../modules/wafer.scad>

```
- and lastly copy in the `common_params.scad` in to your `your_new_idt_layout.scad`, these are just common parameters that each design need such as frequency and speed of sound in your substrate.
- now you can add as many idts to the wafer as you want.

check out `single_idt.scad` and `quadrant_array.scad` to see what is possible with these scripts.
