BlenderBIM : horizontal extruded IfcArbitraryClosedProfileDef on an IfcWallTyype with Cornice

1. R by RaphaëlVouilloz on 11 May 2023, edited 12 May 2023 #

   Hello,

   I am trying to model a wall with a cornice. If I add an IfcMaterialProfileSet to the IfcWallType, the extrusion is done vertically. Is there a way to edit the orientation of extrusion or should I do it differently?

   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))

       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
