BlenderBIM : horizontal extruded IfcArbitraryClosedProfileDef on an IfcWallTyype with Cornice

  Why not model the cornice seperately from the wall? I think Revit its called wall sweeps? Something similar could be done with IfcWalls which have IfcProfiles?
  And you could 'join' them using an IfcElementAssembly with an IfcWall classifcation?

  How to add a custom profile to the profile manager in BlenderBIM? I want to try to model your wall to see if it's practical.

  Thanks Coen, I have described it here : https://enac-cnpa.github.io/BlenderBIM-Tutoriel-Villa-Le-Sextant/5_modelisation-ifc.html under IFC Profiles
  ->Just add a Profile under Scene>IFC Geometry, choose IfcArbitraryClosedProfileDef in the list and click Edit Profile

  Thanks, I should learn to bookmark that useful website

  Sorry, to hijack your thread. but when modeling a custom profile I keep gettings this error:

    File "C:\Users\cclaus\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\blenderbim\libs\site\packages\ifcopenshell\api\geometry\add_profile_representation.py", line 98, in get_point
      return self.file.createIfcCartesianPoint((self.get_x() / 2, self.get_y() / 2, 0.0))
    File "C:\Users\cclaus\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\blenderbim\libs\site\packages\ifcopenshell\api\geometry\add_profile_representation.py", line 139, in get_x
      x = [verts[i] for i in range(0, len(shape.verts), 3)]
    File "C:\Users\cclaus\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\blenderbim\libs\site\packages\ifcopenshell\api\geometry\add_profile_representation.py", line 139, in <listcomp>
      x = [verts[i] for i in range(0, len(shape.verts), 3)]
  NameError: name 'verts' is not defined. Did you mean: 'vars'?
  

  After clicking the Edit Profile Checkmark it happen.

  I think that in Revit you can define a horizontal extrusion profile for a wall. This is useful for many other things than cornices, for example a wall with a sloping side :)

  The cornice can be a separate IfcCovering element with PredefinedType MOLDING

  Click on "Edit Axis" in the toolshelf and place the axis horizontally

  

  Or That ? https://community.osarch.org/discussion/1467/picking-the-direction-your-layersets-go-horizontally-or-vertically#latest

  I haven't tried yet, but does your answer lie here? https://community.osarch.org/discussion/1467/picking-the-direction-your-layersets-go-horizontally-or-vertically

  Perfect! But could we imagine it in the type?

  Yup ! A small variation on @theoryshaw 's screengrabs

  

  Edit : Wait no it doesn't work for axis based sweeps representations. I dunno then. Maybe it's because the axis can be in any direction, there is no general consensus on where it should point.

  That's cool but I need an IfcMaterialProfileSet and not IfcMaterialLayerSet :) Then this doesn't work
