Problema: Cómo obtener referencias a archivos externos (CADNET-110).
Consejos: Para obtener referencias a archivos externos para dibujos en el bloque de entidad, hay un campo XRef PathName para imágenes de ráster. CadRasterImage se utiliza para subyacentes externos, CadDgnUnderlay se utiliza y su campo UnderlayPath.
Ejemplo:
This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

External drawing: | |
foreach (CadBaseEntity baseEntity in image.Entities) | |
{ | |
// if entity is a block | |
if (baseEntity.TypeName == CadEntityTypeName.INSERT) | |
{ | |
CadInsertObject insert = (CadInsertObject)baseEntity; | |
CadBlockEntity block = image.BlockEntities[insert.Name]; | |
// get external reference to object | |
System.Console.WriteLine(block.XRefPathName); | |
} | |
} | |
External raster image: | |
foreach (CadBaseObject baseObject in image.Objects) | |
{ | |
// if entity is an image definition | |
if (baseObject.TypeName == CadObjectTypeName.IMAGEDEF) | |
{ | |
CadRasterImageDef rasterImageDef = (CadRasterImageDef)baseObject; | |
// get external reference to object | |
System.Console.WriteLine(rasterImageDef.FileName); | |
} | |
} | |
External underlay: | |
foreach (CadBaseEntity baseEntity in cadImage.Entities) | |
{ | |
if (baseEntity.TypeName == CadEntityTypeName.DGNUNDERLAY) // or DWFUNDERLAY, or PDFUNDERLAY | |
{ | |
CadDgnUnderlay dgnFile = (CadDgnUnderlay)baseEntity; // or CadDwfUnderlay, or CadPdfUnderlay | |
System.Console.WriteLine(dgnFile.UnderlayPath); | |
} | |
