Viewer in WPF application

[cesarecaoduro]

It might be a stupid question but I can't find a straight forward way to visualize the model in the 3D control after I open it with the IfcStore and convert it.

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

                    tb_output.Text = $"{model.FileName}\n";
                    try {
                        //Add multiple IFC types
                        var reqProducts = new IIfcProduct[0]
                            .Concat(model.Instances.OfType<IIfcElementAssembly>())
                            .Concat(model.Instances.OfType<IIfcBuildingElementProxy>());

                        tb_output.Text += $"Object count: {reqProducts.Count()}\n";

                    }
                    catch (Exception ex) {
                        tb_output.Text += $"Error: {ex.Message}\n";
                    }

What is the process? I can't find tutorial of good examples and the XBim explorer is hard to understand at the beginning.

I think you just need to bind the model instance to the Model property of the DrawingControl3D component (which it looks like you've got running in the screenshot.)

If you want a simple example have you looked at https://github.com/xBimTeam/XbimWindowsUI/tree/master/Xbim.WinformsSample ?

While it's a Winforms sample it's actually wrapping the XAML control so doing the same things...

I saw the example but it keeps saying that the application can't find the interop engine which is in the folder

What's the exact message?

What versions of XBim.Geometry are you using?

It finally worked downloading all the references. Probably the nuget manager didn't download all the referenced packages.
