3D Drawing Rendered Incorrect in PDF

Aspose.CAD Product Family
1

Hello,

Can you tell me if the following type of DWG document is supported, and if not, is there any time frame for support?

This document is a 3D image of some buildings. and when I convert it to PDF, the layout is flat and incorrect.

See sample document and PDF generated: Campus.zip (2.2 MB)

I am testing for the presence of 3D images/entities, using the following code from the forum but I am confused: the following code will always return if3d = false if any 2d entities in the collection are found after a 3d entity is found.

bool if3d = false;
foreach (Aspose.CAD.FileFormats.Cad.CadObjects.CadBaseEntity obj in cadImage.Entities)
{
	//     IterateCADNodes2(entity);
	if (obj.TypeName == Aspose.CAD.FileFormats.Cad.CadConsts.CadEntityTypeName.FACE3D || 
	    obj.TypeName == Aspose.CAD.FileFormats.Cad.CadConsts.CadEntityTypeName.SOLID3D)
    {
		if3d = true;
	}
	else
	{
	    if3d = false;
    }
}

Thanks,

@sheri_steeves,

I suggest you to please try using following alternate in your application to render 3D perspective.

        foreach (CadBaseEntity obj in image.Entities)
        {
            //Console.WriteLine("Obj Name" + obj.TypeName);
            //     IterateCADNodes2(entity);
            if (obj.TypeName == CadEntityTypeName.FACE3D || obj.TypeName == CadEntityTypeName.SOLID3D)
            {
                if3d = true;
                break;
            }
            else
            {
                if3d = false;
            }
        }

I already tried that and the output was worse:

This was my detect 3D code:

foreach (CadBaseEntity obj in image.Entities)
{
    //Console.WriteLine("Obj Name" + obj.TypeName);
    //     IterateCADNodes2(entity);
    if (obj.TypeName == CadEntityTypeName.FACE3D || obj.TypeName == CadEntityTypeName.SOLID3D)
    {
        if3d = true;
    }
}
