WexBim viewer is not showing the geometry correctly

[kovacevski]

Hello,

I have IFC file exported from Archicad. When open in BimVision, the model looks good, but when open in the wexbimviewer it somehow cut the geometries. I am just simply saving the file using:

            using (var model = IfcStore.Open(fileName))
            {
                var context = new Xbim3DModelContext(model);
                context.CreateContext();

                var wexBimFilename = Path.ChangeExtension(fileName, "wexBIM");
                using (var wexBiMfile = File.Create(wexBimFilename))
                {
                    using (var wexBimBinaryWriter = new BinaryWriter(wexBiMfile))
                    {
                        model.SaveAsWexBim(wexBimBinaryWriter);
                        wexBimBinaryWriter.Close();
                    }
                    wexBiMfile.Close();
                }
            }

Thank you. SimpleShed.zip

Which versions of Geometry and wexbim UI are you using?

Can you show the code you use to generate geometry? Have you tried using the adjustWcs param on Xbim3DModelContext.CreateContext() - from the image it looks like the kind of floating point precision issue you get when using large offset coordinates.

Hi Andy,

Exactly, the problem occurs only when I have large offset. I haven't tried adjustWcs, I will try and let you know.

Thank you.

Also, some of the walls are not showing on this file. TestModel.zip

I am using XBimGeometry 5.1.437 and @xbim/viewer 2.1.0-pre202403281736

Hello,

Any clue why the walls with openings are not showing in wexbim viewer?
