Need IMesh help

I’m trying to make a model, specifically 2 pontoons for a plane with IMeshes but it seems it would take forever to make using a notepad.

I want to know if there’s a faster way to making a model using IMeshes and Building it from Triangles? I’m planning to also use PhysicsFromMesh to make a physics obj for it.

Perhaps there are modeling programs that allow to export the positions for the triangles?

iirc someone was working one on.
