IfcOpenShell Error

[chakkree]

GoogleDrive Link https://drive.google.com/file/d/0B5lAIA ... sp=sharing for IFC file i need to open.

I already download project2.ifc(twice for sure).
At first, I tested by open with BIM Vision and Solibri Model Viewer. The result, both is can not open an ifc file.(Very Strange)

Next, open "project2.ifc" with NotePad++. Found that an image below.
Some Error is from the export process, about line no.83416.
It's not a pure text file. There is no any program to open this file.

@chakkree

I checked file with leafpad (a notepad for lubuntu) and foundo no problem.

I uploaded file again, here is the new link : https://drive.google.com/open?id=0B5lAI ... UVmV1hmQUU

But i think that problem has nothing to do with file, because no matter if i try to open my file o IFCOpenHouse.ifc i get the same error in freecad 0.16 and freecad-daily 0.17

@mezeq79 this error of yours:

Code: Select all

products = ifcfile.by_type(ROOT_ELEMENT)
...
<type 'exceptions.RuntimeError'>: Unable to find find keyword in schema

means that the root element (the "highest level" IFC element to import) is not found in the IFC schema. The default root element should be "IfcProduct", it can be changed in the Ifc preferences. Please check that you didn't change it by accident? If needed reset it to IfcProduct (or leave the field empty, which should set it to IfcProduct automatically)

You should first be sure your FreeCAD and IfcOpenShell are able to open ifc files at all before trying to open a huge special ifc-file.Try the IfcOpenHouse file:

This is of course a great idea. I would like to update the wiki to add this check after the "import IfcImport" check. Should I include bernd's advise to change the preferences? or should that be the default preference? I don't really know the implications.

good, but if we could add few ifc related unit tests it would be even better

Agreed but, ifc isn't a core dependency. We would have to at least make a Ubuntu ifcopenshell python27 package and OSX too. The Ubuntu package is already on my list, as a PPA, hosted either standalone or on the FreeCAD community extras page. On Windows it's bundled but I'm behind keeping it current. bernd has posted a more recent build though for x64. viewtopic.php?f=23&t=16475#p131460

@yorik you were right.

The Root Element in preferences from Arch workbench was set to 'ProductoIfc' which is the spanish translation of 'IfcProduct'.
As soon as i changed it it worked for both Freecad and Freecad-Daily.

The problem is that i didn't change it, because i didn't even knew of its existance, so i suppose it has to be a problem with Spanish language package?

Can it be cosidered as a minor bug and send to Spanish developers?

Appreciate all your help.
Thank you very much

good point

@yorik you were right.

Common occurrence in FreeCAD. The experts did notice
Sorry @mezeq79 for high-jacking your thread Great question though that fosters a new discussion viewtopic.php?f=23&t=16785

[mezeq79]

It would be good than this error and solution to spanish Freecad installation stays clear.

Error on every Ifc file:

products = ifcfile.by_type(ROOT_ELEMENT)
...
<type 'exceptions.RuntimeError'>: Unable to find find keyword in schema

Says that ROOT_ELEMENT is not set to IfcProduct on Freecad.

If you are using any of Freecad "spanish translated" versions, must check in "Edit->Preferences->Import/Export->Ifc" of Arch workbench ROOT_ELEMENT value.

It must be kept empty or write 'IfcProduct' because there is a translation error.

Thank you
