How are all open breps combined by Simple mesh component

[木村亘 (Wataru)]

Hello guys, I’m a beginner at GH.
I’m trying to do an origami simulation with crane plug-in.
I followed this tutorial, then after that I tried to make a crane(doesn’t mean plug-in nema) with same script as the tutorial.

Grasshopper Tutorial (Origami With Crane)

As you can see the photo, base surface has some holes. and this is caused in Simple mesh component.
Do you guys know how to fix it?

Thank you for letting me know a tip. These are my rhino file and gh script. I used geometry pipeline, so open both files, please.

You have ngons.

Try to eliminate them.
