Enum VoidShellNormals 

pub enum VoidShellNormals {
    AwayFromMaterial,
    TowardMaterial,
}

Which way the face normals of the void shells passed to StepBuilder::solid_with_voids point. The caller declares this so step-io can orient each cavity’s ORIENTED_CLOSED_SHELL correctly without evaluating geometry. See that method for how to choose.

Variants

AwayFromMaterial

Normals point away from the solid material — for a cavity, into the empty hole. This is the same rule the outer shell follows, the validator- and mass-property-friendly orientation, and what most kernels emit for a cavity (a reversed shell). Kept as authored, written as ORIENTED_CLOSED_SHELL(..., .T.). The right choice when unsure.

TowardMaterial

Normals point into the solid material — a cavity wound like an ordinary outward-facing solid box dropped into the hole. step-io reverses it, written as ORIENTED_CLOSED_SHELL(..., .F.).
