Convertire DWG in PDF con Coordinate

Come convertire DWG in PDF con Coordinate

Aspose.CAD offre la possibilità di caricare il file AutoCAD DWG e esportarlo nel formato PDF fornendo coordinate. Per questo, l’API fornisce la classe CadVportTableObject. La classe CadVportTableObject viene utilizzata per specificare le coordinate per la conversione.

Il campione di codice sottostante mostra come convertire un file DWG in formato PDF fornendo coordinate utilizzando Aspose.CAD per .NET in C#.
