Similar to #4124 the following IFC does not open in BB. It might be related.

It 'acts' like it opens, but nothing is in the outliner.

Here's the console output, as well, if it will help.

o = placement.Location.Coordinates
AttributeError: 'NoneType' object has no attribute 'Coordinates'

This would potentially be rather easy to fix:

f = ifcopenshell.open(...)
for inst in f.by_type("IfcPlacement"):
  dim = int([c for c in inst.is_a() if c.isdigit()][0])
  if inst.Location is None:
    inst.Location = f.createIfcCartesianPoint([0.] * dim)
f.write(...)

This would potentially be rather easy to fix:

In this case it's 1 IfcAxis2Placement3D element and dim = int([c for c in inst.is_a() if c.isdigit()][0]) will result in 2d point for it instead of 3d 🤔

@theoryshaw you can run snippet below from Blender scripting tab and it will manually fix the problem and file will load.

import ifcopenshell
filepath = r"C:\Restaurant_Pewaukee - Copy.ifc"
f = ifcopenshell.open(filepath)
for inst in f.by_type("IfcPlacement"):
  if inst.Location is None:
    inst.Location = f.createIfcCartesianPoint([0.] * 3)
f.write(filepath)

The problem was with just 1 placement element not having location (though it's not optional). This placement is part of Body/Tessellation representation of element
#2850821=IFCFURNITURETYPE('3ZuQlI_kTCWgpWkLFPrpam',#2848690,'Chair - Deja 1',$,$,(#2848692),(#2850761,#2850811,#2885073),'3606448',$,.NOTDEFINED.,.NOTDEFINED.);. Any ideas what could have caused this?

Thanks Guys, this script seems to work.

Any ideas what could have caused this?

Unfortunately nothing comes to mind. I'll keep my eyes open, if this happens again.

This happened again, unfort.

@Andrej730
How did you debug and troubleshoot to find the following problematic object?
#2850821=IFCFURNITURETYPE('3ZuQlI_kTCWgpWkLFPrpam',#2848690,'Chair - Deja 1',$,$,(#2848692),(#2850761,#2850811,#2885073),'3606448',$,.NOTDEFINED.,.NOTDEFINED.);

I use VScode, so I can try to do it on my side to figure out what object(s) it is, and it might jog my memory as what I might have 'did to it' to have it lose its coordinates.

Did you debug while running the script? or while opening the file?

@theoryshaw

I think i figured out a way...
put a breakpoint here...

and then just found the ID number of the inst, and then just searched that ID in the .ifc file.

Prior to finding https://github.com/hextantstudios/hextant_python_debugger I usually would put a breakpoint() around the line that failed and debug it from system console. With the addon debugger it's now possible to add those checkpoints from VS Code.

Another note that typically many errors like this when something is missing some IFC attribute occur due invalid IFC file - it's possible to run the validation and search the either for missing attribute or for some entity name (e.g. "Placement") and find something related.
