# Introduction |

|
OpenSCAD. |

# How to install |
|
|
|
Short instructions how to install sheetstruder, I will send some |
|
documentation upstream. You need git and python and later you will need |
|
openscad and a spreadsheet tool. |
|
|
|
```shell instructions |
|
git clone https://git.hackers.town/seachaint/sheetstruder.git |
|
cd sheetstruder |
|
python3 -m venv sandbox |
|
. sandbox/bin/activate |
|
python3 -m pip install -r requirements.txt |
|
``` |
|
|
|
You will need to be in this shell (you need at least the activate |
|
command) to make it work. |
|
|
|
# How to use |
|
|
|
Open a spreadsheet tool that is able to export in format xlsx, type a |
|
number to create a solid object of this width (1 = 1 pixel, 2 = 3 |
|
pixels because it's mirrored) and put a background color in your cell. |
|
Save your file as xlsx. |
|
|
|
Run "python3 ./sheetstruder.py yourfile.xlsx > file.scad" and open the |
|
file in OpenSCAD, enjoy! |
