Title: Use Libreoffice Calc to make 3D models Author: Solène Date: 27 April 2021 Tags: fun Description: # Introduction Today I will share with you a simple python script turning a 2D picture defined by numbers and colors in a spreadsheet into a 3D model in OpenSCAD. (HTM) Project webpage # 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! # Examples I made a simple house with grass around, an antenna, cheminey with smoke, a door and window in it.
