My second attempt at armor

[ImBoredForFun]

I'm looking to make a set of mark VII armor from halo infinite and I am very excited to begin, but as I've started I hit a hitch.
Whenever I cut the model with the plane cut tool in meshmixer it is entirely hollow is there a way I can fix this?

I'm using this helmet model by moesizzlac.

There should be a few options that appear when you select plane cut. On the left side of you screen, you should see a drop down for "fill type". There's four options in there. I forget which one is the one that fills the gap you create when cutting but that is indeed the setting to mess with.

some slicer aplications have a slice feature in them that will also fill the gap left behind. for exsaple orca slicer
