3dpolyline to IfcAnnotation

in General

i am trying to export a 3d polyline to ifc 4
(no profile, no curve on surface,...)
i thought IfcAnnotation would be the right class for displaying the curve in ifc
i am failing to modify my curve (Standard_curve_extrusion[]) to an IfcAnnotation
what am i missing
Blender 4.2
BlenderBIM 0.7.10.240718
thank you

    Hi @PeterKop
    It might be one of two things
    1) You need to classify the polyline as a mesh before assigning it as an IfcAnnotation
    and
    2) it needs to be hosted inside of a drawing view
    Try it out let us know if you come right
