I tried converting according to this link but got an error:

Does anyone have a way to convert from dwg file to gltf? Please support me.

You can please use Aspose.CAD and Aspose.3D to do this job. First convert the .dwg to .obj file using Aspose.CAD, and then use Aspose.3D to convert .obj to .gltf.

@asad.ali Thanks you!.

I tried to do the same as you and exported the gltf file. But when I use the tool to view it, I can’t see anything.

Would you please share your sample source files along with sample code snippet? We will test the scenario in our environment and address it accordingly.

@asad.ali send to you source code and dwg file.

My code:

if (openFileDialog.FileName.EndsWith(".dwg"))
                    //Load file dwg by Aspose.CAD
                    Aspose.CAD.License license = new Aspose.CAD.License();
                    Aspose.CAD.Image image = Aspose.CAD.Image.Load(openFileDialog.FileName);
                    CadImage cad = (CadImage)image;
                    var options = new Aspose.CAD.ImageOptions.ObjOptions();

                    //Export file dwg to obj by Aspose.CAD
                    var fileName = openFileDialog.FileName.Replace(".dwg", ".obj");
                    image.Save(fileName, options);

                    //Load file obj by Aspose.3D
                    Aspose.ThreeD.License license1 = new Aspose.ThreeD.License();
                    Aspose.ThreeD.Scene scene = new Aspose.ThreeD.Scene(fileName);

                    //Convert file obj to glb by Aspose.CAD
                    GltfSaveOptions saveOptions = new GltfSaveOptions(Aspose.ThreeD.FileContentType.Binary);                    
                    var fileName1 = fileName.Replace(".obj", ".glb");
                    scene.Save(fileName1, saveOptions);

Can you share the generated .obj and .glb file? The .glb file we generated on our side does have something in the online .gltf viewer and in our Windows’ built-in 3D viewer.
