Hi all,

Allplan 2020 no "ifc export" correctly some profiles from the new "structural framing", to IFC: Allplan not add the important IfcClass of Profile Definitions, in some kind of beam/column profiles.

-------------------
General Explanation

In an IFC file that contents IfcColumns and IfcBeams, they can have two ifc classes that defines/explain the kind of profile of those elements:

1- IfcClass for Profile definition: is a must ifcclass. Always it must be inside IFC file. The name of this class is different:
1.1- For rectangle profiles: IFCRECTANGLEPROFILEDEF
1.2- For other profiles (HEB,etc..): IFCARBITRARYCLOSEDPROFILEDEF

2- IfcClass Generic: this generic class, it saves the parameter and the value from allplan. The "Profile name" parameter of allplan and his value, will it saved in the ifcclass "IFCPROPERTYSINGVALUE".

---------------
Issues detected

In IFC export process (the new process), Allplan not create the ifcClass of profile definition, in the next kind of profiles of the new "structural framing tool":

- Columns : Rectangular profile
- Columns : Circular profile
- Beams : Rectangular profile
- Beams : Circular profile
- Beams : HEB, IPE, etc.....

I attach 2 images, and a zip (contains IFC and ndw files), to explain it.
