Missing layer in the PDF rendering file

Aspose.CAD Product Family
1

We have implemented the generation of PDF files from .dwg files.
However, in some cases, some layers are missing.
We are using the version 23.6.0 and the conversion is done as followed :

using (var cadImage = (CadImage)Aspose.CAD.Image.Load(msSource))
{
    var layers = new List<string>();
    foreach (CadLayerTable layer in cadImage.Layers)
    {
        layers.Add(layer.Name);
    }
    var rasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions()
    {
        DrawType = CadDrawTypeMode.UseObjectColor,
        PageWidth = cadImage.Width,
        PageHeight = cadImage.Height,
        UnitType = cadImage.UnitType != Aspose.CAD.ImageOptions.UnitType.Unitless ? cadImage.UnitType : cadImage.UnitlessDefaultUnitType,
    };
    cadImage.Save(msTarget, new Aspose.CAD.ImageOptions.PdfOptions()
    {
        VectorRasterizationOptions = rasterizationOptions,
        Layers = layers.ToArray(),
    });
}

Could you tell me what is missing ?

Thanks.

You’ll find attached an example file where the layer “*LayerNameForDynamicConstraint” is missing.

@pvanloo,
we checked this case and saw that mentioned layer is not missing at export. But it contains only entities (dynamic dimensional constraints) that were not designed to be plottable. The file does not contain enough information to plot them properly. So it seems the only way to export them is to convert to regular dimensions.

Thank you Oleskii for your answer.
Therefore, could you tell how it is possible to export such layer.
In fact, if I open this document with other tools, such as All in pdf or ShareCAD, this layer is correctly displayed.

Kind regards,
Patrick

We will consider the implementation of support for these entities, but AutoCAD, ODA Viewer, DWGSee don’t plot them too :slight_smile: Please share the file with the expected result from any other tool.
