After some try :)

- You can draw directly in Moi3D (works with the colors given by default! Black, Blue, Red, Magenta, Green - you must create a new one for Yellow)
- Export as PDF (view Top)
- Open inside the free Gravit Designer https://www.designer.io (View / Fit Canvas)
- Save as SVG File ( file must have small letters for the extension .SVG so .svg :)

You can now use the Origami Simulator Online and Import the file .svg

Here Fold Percent was limited to 60 % (in Origami Simulator itself - advanced Options )



Some Draw Lines in Moi, an edge is selected to verify its color!


You can play with opacity for the angle of folding (Mountain / Valley)
