How do I make path3d smoother

Question

I created a new path3D, but it doesn’t have many in between segments and it is all pointy.
How do i smooth it out?

The arrows are only a representation of the path, it is usually much smoother when applied to a PathFollow3D or sampled in code.

I used CSGPolygon3D to fill the path but even when it has a low path interval the path is still a really rough.
