Making a paper craft on Linux/macOS with OSS Memo

background

• For some reason, I wanted to make a paper craft that would be very popular with talented young people.
• I want to make from a 3D model in Blender
• There is a paper model designer https://tamasoft.co.jp/pepakura/, but it only works on Windows.

procedure

Thank you.

• Make a model with Blender.
• Export as .obj
• Convert to .obj-> DXF with MeshLab
• Convert with dxf2papercraft (expand + add glue)
• DXF! It's a nostalgic file format!
• Read DXF with LibreOffice Writer, convert to SVG and export

Will be!

dxf2papercraft

You need to build it yourself. You will need the DXF library dime.

After that, if necessary, you can set the path to dime and make it without any problem (M1 macOS)

result

It works reasonably well with cube and icosphere, but ... (There is a little margin)

I couldn't do torus because it was different for each face.

Summary

dxf2papercraft doesn't work very well. It seems that it needs to be made with Manifold and low poly.

Alternative

Blender's UV unfolding + manual gluing may be good!

TODO

• [] I want to develop UV directly from .obj with xatlas and add my own margin
• [] SIGGRAPH I would like to implement paper craft related papers and capture the hearts of excellent young people.
