3dpolyline to IfcAnnotation

  1. P by PeterKop on 19 Jul 2024, edited 29 Jul 2024 #

    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

    1. it needs to be hosted inside of a drawing view

    Try it out let us know if you come right
