Working with CAD metadata Leave feedback
The GroupDocs Metadata API provides the feature to read basic metadata in CAD files. The supported CAD formats are:
- DWG
- DXF
To access metadata in a CAD drawing, the GroupDocs.Metadata API provides the CadRootPackage.getCadPackage method.
The following code snippet reads metadata associated with a CAD file.
advanced_usage.managing_metadata_for_specific_formats.
try (Metadata metadata = new Metadata(Constants.InputDxf)) {
CadRootPackage root = metadata.getRootPackageGeneric();
System.out.println(root.getCadPackage().getAcadVersion());
System.out.println(root.getCadPackage().getAuthor());
System.out.println(root.getCadPackage().getComments());
System.out.println(root.getCadPackage().getCreatedDateTime());
System.out.println(root.getCadPackage().getHyperlinkBase());
System.out.println(root.getCadPackage().getKeywords());
System.out.println(root.getCadPackage().getLastSavedBy());
System.out.println(root.getCadPackage().getTitle());
// ...
}
The GroupDocs.Metadata API also allows updating metadata properties in a DXF drawing. Please check the code sample below.
advanced_usage.managing_metadata_for_specific_formats.
try (Metadata metadata = new Metadata(Constants.InputDxf)) {
CadRootPackage root = metadata.getRootPackageGeneric();
root.getCadPackage().setProperties(new WithNameSpecification("Author"), new PropertyValue("GroupDocs"));
root.getCadPackage().setProperties(new WithNameSpecification("Comments"), new PropertyValue("test comment"));
root.getCadPackage().setProperties(new WithNameSpecification("HyperlinkBase"), new PropertyValue("test hyperlink base"));
root.getCadPackage().setProperties(new WithNameSpecification("Keywords"), new PropertyValue("test keywords"));
root.getCadPackage().setProperties(new WithNameSpecification("LastSavedBy"), new PropertyValue("test editor"));
root.getCadPackage().setProperties(new WithNameSpecification("RevisionNumber"), new PropertyValue("test revision number"));
root.getCadPackage().setProperties(new WithNameSpecification("Subject"), new PropertyValue("test subject"));
root.getCadPackage().setProperties(new WithNameSpecification("Title"), new PropertyValue("test title"));
root.getCadPackage().setProperties(new WithNameSpecification("CreatedDateTime"), new PropertyValue(new Date()));
root.getCadPackage().setProperties(new WithNameSpecification("ModifiedDateTime"), new PropertyValue(new Date()));
metadata.save(Constants.OutputDxf);
}
