I've tried using an older version of IfcConvert: commit reference, and the output was as expected. I noticed that the issue seems to occur only when using the -j parameter for multicore processing (in this old version). Without this parameter, everything works fine. It seems like a recent update might have introduced this problem.

Hi everyone, I'm currently facing an issue while trying to convert an IFC file to an OBJ file using IfcConvert. I'm running the following command with the latest version of IfcConvert: IfcConvert.exe path/to/ifc.ifc path/to/obj.obj --y-up However, the output is not as expected. Here’s what the original IFC looks like: And here’s what the resulting OBJ looks like: As you can see, some columns and beams are missing in the OBJ file.

Finally, I was able to solve the issue by using IfcOpenShell to center the model before performing the IFC conversion. However, I still believe there might be an issue with the --building-local-placement and --center-model parameters that should be investigated. For anyone facing a similar problem, here's the code I used: import ifcopenshell model = ifcopenshell.open('path/to/file/input.ifc') site = model.by_type('IfcSite')[0] placement = site.ObjectPlacement.RelativePlacement placement.Location.Coordinates...

Thank you for your input regarding the large offsets in the coordinates of the .obj file. You were correct in identifying that the issue was related to the IFC being geolocated. By relocating the model back to the origin, the problem was resolved. However, I was only able to achieve this by using Revit and saving a copy of the IFC centered at (0, 0, 0) without geolocation. Using the parameters --building-local-placement or --center-model as you suggested did not yield the expected results. The generated...

Thomas Krijnen posted a comment on discussion Help
I think what might be happening is that there is a large offset somewhere so the coordinates in the .obj are large / far away from origin. This causes issues in software that uses less precision. You might want to try running ifcconvert with --building-local-placment to ignore transformations in the spatial hierarchy from building and upwards where usually such large offsets are introduced.

@aothms - I know this is an old post, but your post specified #define SCHEMA_VERSIONS=(2x3)(4) which includes a typo I think. There should be no '=', so if it's changed to #define SCHEMA_VERSIONS (2x3)(4)" that seems to work. Thanks for the excellent library.

load specific elements by their GUID into the iterator? I saw, one could filter elements like 'IFCWALL' etc., but by guid..? include= excepts either a list of strings in which case it is assumed to be entity types. You can also pass a list of ifcopenshell.entity_instance (that you obtained with file.by_guid).
-
Hm, I couldnt find how DISABLE_TRIANGULATION gives me IfcGeom::BRepElement. Using get_native() in the iterator works! Is it possible to just load specific elements by their GUID into the iterator? I saw, one could filter elements like 'IFCWALL' etc., but by guid..? I am sorry, just starting off with IfcOpenShell, still need to wrap my head around some things. Great to hear, that the ray intersections might be updated, looking forward to that!

That's an OPEN/SAVE entire IFC project, not import/export. In Blender 3.5 I was able to import IFC object exported from ArchiCAD (not entire project, but selected object) and insert it to the already opened IFC project at a correct place represented in the ArchiCAD. Now I have to open single exported object in a new Blender instance and copy/paste it into the working Blender project.

Seems like latest version of IfcOpenShell does not work for Blender 4.0
-
The setting you're looking for is DISABLE_TRIANGULATION. If you use ifcopenshell.geom.iterator you can also call get_native() regardless of the setting. Btw. we're working on a much more powerful tree implementations. https://github.com/IfcOpenShell/IfcOpenShell/pull/4374 that will eventually also greatly speed up ray intersections. Currently ray intersections are still a bit brute force on the tree. Nothing concrete to show yet, but in a couple of weeks something might be ready.
-
I want to select elements by a ray. Now loading the whole IFC file in my geometry tree is overkill, I just need two elements by guid. tree.add_element() needs an IfcGeom::BRepElement. How can i create such an element from my shape? I see that using USE_PYTHON_OPENCASCADE and USE_BREP_DATA gives me brep_data and a TopoDS_Compound. I also tried using the iterator, but dont know, how two only add two elements instead of the whole file. Thank you!

Hi, just wondering if anyone knows of a free and easy to use online file converter for photographs? They were taken with a nikon camera and are .nef files which I would like to convert to .jpeg. I am using the latest Mint edition which allows me to view them, but I need to convert them for other family members. Thank you.

Hi, I try to get materials of elements but unfortunately no RelatingMaterials are defined in the Psets. In Blender, however, the material is clearly defined. It appears to be inherited. Is there a way to query the "IFC Object Material" directly as it appears in Blender? Thanks for your help.

Thanks Thomas - apologies, i should have looked at the schemas - a simple change to IFC4X3 fixes my problem.

There exist three pset templates ./src/ifcopenshell-python/ifcopenshell/util/schema/Pset_IFC2X3.ifc ./src/ifcopenshell-python/ifcopenshell/util/schema/Pset_IFC4X3.ifc ./src/ifcopenshell-python/ifcopenshell/util/schema/Pset_IFC4_ADD2.ifc I thought that with the latest schema handling changes IFC4X3 will be used for all revisions of IFC4X3 including _TC1.

I found the answer to my own question - thought i would post here in case it helps other newbies. If you look at easch of the modules in the library it gives a really good description of how they work. In some instances this is much easier to follow than trying to find instructions or examples on line. In this case root.create.entity will only add predefinedType and name.

I want to create some piles in an ifc file (which i am creating without any geometry just to demonstrate something).

Following further investigation the issue seems to be somewhat more complex.

Following further investigation the issue seems to be related to IfcBeams only in the test project where I first noticed incorrect dims. It looks like this might be related to calculating bbox for extruded profiles. Did anyone come across similar problems?

I have just realised that the getbbox function gets me the bounding box according to global coordinates. This means that when I use it to calculate size of objects that are rotated from XYZ axes I get incorrect results. Is there any way to use this on the local coordinates? E.g. is there an equivalent of vertices = getvertices(geometry) getting the vertices as per local object's coordinates?

Many thanks for the hint - I can imagine this could make a huge difference. I still didn't get my code to work with ifcopenshell.geom.iterate(), but if I find a solution I will post it in here.
-
Instead of ifcopenshell.geom.create_shape() you better use ifcopenshell.geom.iterate(). That way there is a global context to share and cache shared representation of various elements, which sounds like in your case it could speed up the runtime quite dramatically. Other than that, IFC allows for some pretty computationally expensive geometric forms.

That's excellent - I managed to extract my XYZ dimensions to a dataframe with the code below. It works great with small amount of objects but when I try to extract all bounding box data from a large file (hospital project, only 50 MB, but a very big building with lots of parts) it takes good half an hour - is this normal or did I mess something with that code? `def process_ifc_element(element): try: settings = ifcopenshell.geom.settings() representation = element.Representation.Representations[0]...

By calculating boundig box I mean calculating and not just extracting the data from the IfcBoundingBox (which in case of the files I am parsing does not exist). Ideally if there was a function in IfcOpenShell already - this would be amazing!

Many thanks @aothms!

See below. You have to actually pass the schema identifier to the file being created. import ifcopenshell from ifcopenshell.api import run # Create a blank model model = ifcopenshell.file(schema="IFC4x3") # Create Spatial Structure project = run("root.create_entity", model, ifc_class="IfcProject", name="Spatial Structure Trial") site = run("root.create_entity", model, ifc_class="ifcSite", name="TrialSite") facility = run("root.create_entity", model, ifc_class="ifcMarineFacility", name="OpenPort")...

Im trying to construct a simple spatial structure with IfcOpenShell as a demonstration of the new spatial elements in Ifc4.3 but i cant get it to work (Im a Python / IfcOpenShell novice). Ive re-purposed some code from various examples but i cant get it to work wiht IfcMarineFacility, only with IfcBuilding. Is there something simple that im doing wrong? When i view the .ifc file it seems to have set the schema to Ifc4 (rather than 4.3)? Any guidance would be much appreciated. Dan

Currently no such thing exist. Help is always welcome :) https://github.com/IfcOpenShell/IfcOpenShell/issues/203

Hi, where can I find the XSD of the XML generated by IfcConvert?

It appears you are correct that the deletion of those two files only happens when the serializer object is being destructed https://github.com/IfcOpenShell/IfcOpenShell/blob/v0.7.0/src/serializers/GltfSerializer.cpp#L60-L61 This can be accomplished with del sr in Python, although strictly speaking you never actually know in Python when the object actually gets freed. You might have to add import gc; gc.collect(). The actual result file is a member object of the class https://github.com/IfcOpenShell/IfcOpenShell/blob/v0.7.0/src/serializers/GltfSerializer.cpp#L52...

Because you've added: with_progress=True You get return a pair of progress as integer and the currently processed elem. So either change to with_progress=False or to for progress, elem in ifcopenshell.geom.iterate(

Alternatively, I am trying to convert using ifcopenshell-python, but it seems to fail with errors. Here is the code. fn = ifcopenshell.open(ifc_file) ifcopenshell.ifcopenshell_wrapper.turn_off_detailed_logging() ifcopenshell.ifcopenshell_wrapper.set_log_format_json() settings = ifcopenshell.geom.settings( APPLY_DEFAULT_MATERIALS=True ) settings.set(settings.USE_ELEMENT_GUIDS, True) sr = ifcopenshell.geom.serializers.gltf(glb_file_name, settings) sr.writeHeader() for elem in ifcopenshell.geom.iterate(...

@aothms, Thank you for your reply, I checked as you suggesed, I noticed only \n characters in the file.

I managed to convert the ifc file into a glb file. I used this code, but i have a problem. After i call .finalize() I have to open the glb file and then upload on CMIS but the file isn't already "finished", in my folder there are vertices and indices tmp files yet. Is there another function to call to "close" the serialized file? f = ifcopenshell.open(filename) ifcopenshell.ifcopenshell_wrapper.turn_off_detailed_logging() ifcopenshell.ifcopenshell_wrapper.set_log_format_json() settings = geom.settings()...
