Enum MemberDraftKind 

pub enum MemberDraftKind {
    Curve {
        predefined_type: MemberPredefinedType,
        axis: Option<EntityId>,
        varying: bool,
    },
    Surface {
        predefined_type: MemberPredefinedType,
        thickness: Option<f64>,
        varying: bool,
    },
}

Staged member subtype for MemberDraft::kind.

Variants

Curve

Stages an IfcStructuralCurveMember.

Fields

predefined_type: MemberPredefinedType

PredefinedType; must be a curve-member role (rigid/pin-joined, cable, tension/compression, user/not defined).

axis: Option<EntityId>

Axis; required when the target schema declares the attribute for this type.

varying: bool

Stage IfcStructuralCurveMemberVarying instead.

The varying subtype adds no attribute: it declares that the axis properties change along the member, which the analysis side reads from the type name alone. Same slots, different claim about the member.

Surface

Stages an IfcStructuralSurfaceMember.

Fields

predefined_type: MemberPredefinedType

PredefinedType; must be a surface-member role (bending/membrane element, shell, user/not defined).

thickness: Option<f64>

Thickness; must be a positive finite value, and mandatory when predefined_type is Shell.

varying: bool

Stage IfcStructuralSurfaceMemberVarying instead.

Thickness on the varying form is the value at a reference point, not a constant; the variation itself is carried by an attached property set, so the slot layout is unchanged.
