3 years ago Hi @CBenghi I shared the file, can you confirm me?
The link expires on the 21st of this month.

3 years ago Confirmed. There is indeed an opencascade violation. I'll have a look.

3 years ago Just for the record... this has failing geometries in several viewers, including Solibri and BimVision. I will still attempt to remove crashing errors, but I would recommend you to attempt another export from the original software once the product families have been adjusted.

3 years ago Thanks for the reply @CBenghi
Just to put it in context, we have a solution as a service where our customers send files to our system, and we convert it to be viewed on the web.
Just so I understand, this problem is related to how the user exports the ifc file from the software he uses, right?

3 years ago That seems to be the problem, yes. We still should be able to prevent crashes, of course, which does not happen in this case. But the file is particularly bad.

3 years ago @CBenghi can you help me with a question?
I wanted to work around this error below.
Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Repeat 2 times:I tried microsoft's own documentation, but I didn't have any success.
https://docs.microsoft.com/en-us/dotnet/api/system.accessviolationexception?view=net-5.0
Is there any way I can catch this error and end my process manually?

3 years ago You should be able to do something using https://docs.microsoft.com/en-us/dotnet/api/system.runtime.exceptionservices.handleprocesscorruptedstateexceptionsattribute?view=net-5.0
I've sometimes done it, which might be useful to exit gracefully, but still not a complete solution.

3 years ago @CBenghi I made sample code using [HandleProcessCorruptedStateExceptions] and I can't seem to catch this error.
Example:
using System.Threading.Tasks;
using System;
using System.IO;
using System.Runtime.ExceptionServices;
using System.Security;
using Xbim.Ifc;
using Xbim.IO;
using Xbim.ModelGeometry.Scene;
namespace XbimConverterTest
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Starting script...");
try
{
ToConvert();
}
catch (System.Exception e)
{
Console.WriteLine("An unexpected error has occurred");
Console.WriteLine(e.Message);
}
}
[SecurityCritical]
[HandleProcessCorruptedStateExceptions]
static void ToConvert()
{
const string fileName = @"RSPA0004-ARQ-EX-URBF-RIF-TORRE_01-R02.ifc.zip";
var wexBimFilename = Path.ChangeExtension(fileName, "wexBIM");
var xbimDbFilename = Path.ChangeExtension(fileName, "xBIM");
// Make sure we are using an IModel implementation that supports saving of '.xbim' files
IfcStore.ModelProviderFactory.UseHeuristicModelProvider();
using (var model = IfcStore.Open(fileName))
{
// IFC file is already parsed and open. Now build the 3D
var context = new Xbim3DModelContext(model);
context.CreateContext(); // Creates the Geometry using native GeometryEngine
// Optional: Export to 'wexbim' format for use in WebUI's xViewer - geometry only
using (var wexBimFile = File.Create(wexBimFilename))
{
using (var wexBimBinaryWriter = new BinaryWriter(wexBimFile))
{
model.SaveAsWexBim(wexBimBinaryWriter);
wexBimBinaryWriter.Close();
}
wexBimFile.Close();
}
// Save IFC to the internal XBIM format, which includes geometry
model.SaveAs(xbimDbFilename, StorageType.Xbim);
}
}
}
}
output
Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

3 years ago Add [HandleProcessCorruptedStateExceptions] in source code does not work for me too. But add this in yourApp.config,
<legacyCorruptedStateExceptionsPolicy enabled="true"/>between
It works.

Sorry for hijacking the issue, but is there already a preview version of xBim.Geometry for .NET Core available that runs on .NET Core 3.1 or .NET 5? I totally missed that😀

The exception
System.AccessViolationExceptionis thrown when trying to convert an ifc file to wexbimAssemblies and versions affected:
Steps (or code) to reproduce the issue:
Minimal file to reproduce the issue:
I cannot make the file publicly available, if someone can pass the email I do it on OneDrive
Expected behavior:
I hope the file will be converted
Actual behavior or exception details:
This is the convention log when I enable the
