@Aleks85,
Hello, could you please attach this test file so we can talk about same values?

@Aleks85,
unfortunately, this seems to be not easy, because these values are stored deeply in the file. I have created CADNET-8844 to investigate this further.

if i convert dwg to dxf. Can I get properties from dxf?

@Aleks85,
yes, it will be easier to see where these values are stored and now we are doing the same - inspecting DXF version of this file. Unfortunately, there are reasons that do not allow to get these values now: we don’t have parsing of some required objects, that are helpful here, and we need to understand better how these values are stored in the file.

@Aleks85,
Hi, here is the example how to get these properties for the DXF format:

using (CadImage cadImage = (CadImage)Aspose.CAD.Image.Load(fileName))
{
	foreach (CadBaseEntity entity in cadImage.Entities)
	{
		if (entity is CadInsertObject)
		{
			CadInsertObject insert = (CadInsertObject)entity;
			CadBlockEntity block = cadImage.BlockEntities[insert.Name];
			CadBlockTableObject blockTable = block.CadBlockTableObject;

			var ref1 = SearchObjectByOwner(cadImage, blockTable.ObjectHandle);
			var ref2 = SearchObjectByOwner(cadImage, ((CadDictionary)ref1).ObjectHandle) as CadDictionary;

			if (ref2 != null)
			{
				CadAcDbAssocNetwork network = SearchObjectByOwner(cadImage, ref2.ObjectHandle) as CadAcDbAssocNetwork;

				List<string> vars = new List<string>();

				foreach (CadParameter param in network.AccosNetworkList)
				{
					if (param.Type == CadEntityAttribute.Cad360)
					{
						CadBaseObject bo = SearchCustomObject(cadImage, ((CadStringParameter)param).Value);
						CadAcDbAssocVariable var = bo as CadAcDbAssocVariable;
						if (bo != null)
						{
							vars.Add(var.VariableName + " ->> " + var.VariableValue);
						}
					}
				}
			}
		}
	}
}

private static object SearchObjectByOwner(CadImage cadImage, string reference)
{
	foreach (CadBaseObject baseObject in cadImage.Objects)
	{
		if (baseObject.SoftOwner == reference)
		{
			return baseObject;
		}
	}

	return null;
}


private static CadBaseObject SearchCustomObject(CadImage cadImage, string reference)
{
	foreach (CadBaseObject baseObject in cadImage.Objects)
	{
		if (baseObject.ObjectHandle == reference)
		{
			return baseObject;
		}
	}

	return null;
}
