Maybe it makes sense to shift to the IFC4x2 spec which is already in draft mode (see https://standards.buildingsmart.org/IFC/DEV/IFC4_2/FINAL/HTML/). It adds new usecases for IfcAlignment and therefore testcases to test. To...

Sure. The inheritance of IfcProduct injects some relations (nesting, relative positioning etc.) and an optional representation. But its expressiveness is about horizontal and vertical positioning of other products. The shape...

Is there any plan to merge the ifcRail branch into develop (at least the changes of geometry handling)? Is there any tutorial how to run the IFC scheme generation (i.e....

Just found a candidate for solution of this. I've had the same trouble while importing meshes to Unity. The problem seems to be related to planar meshing algorithm and orientation...

Yes, I saw your solution. The current patch does the same, since it`s the only way to handle this type of checks stable manner (at least I don't know any...

So, are you using the XbimGeometry project to extract the geometry? In my case, some of the inverted meshes were already wrong in the source IFC. There's already a fix,...

Your example is using IfcClosedShells. When the context is built, XbimGeometry is involved. So you are using it implicitly. I have tried to read your example using the patched version...

Yes. It's actually the way how the final orientation of the overall mesh is determined. The current logic (tries) to place/compute a point on some extreme coordinates at the boundary...

I share your opinion. The first objective should be a more adaptive and verbose input processing methodology. The way of internal processing should rely on a deterministic logic. Otherwise incorrect...

Hi all, if the operations all near / or are within the tolerance thresholds, the order of operations will have an impact on the result. The tolerance is actually not...
