CadPackage class

Represents CAD (Computer-aided design) metadata.

Inheritance: CadPackage → CustomPackage → MetadataPackage

The CadPackage type exposes the following members:

Property	Description
metadata_type	Gets the metadata type.
keys	Gets a collection of the metadata property names.
property_descriptors	Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
count	Gets the number of metadata properties.
acad_version	Gets the AutoCAD drawing database version number.
height	Gets the drawing height.
width	Gets the drawing width.
author	Gets the drawing author.
comments	Gets the user comments.
hyperlink_base	Gets the hyperlink base.
keywords	Gets the keywords.
last_saved_by	Gets the name of the last editor.
revision_number	Gets the revision number.
subject	Gets the subject.
title	Gets the title.
created_date_time	Gets the date and time when the drawing was created.
modified_date_time	Gets the date and time when the drawing was modified.
custom_properties	Gets the package containing custom metadata properties.

Method	Description
`contains(self, property_name)`	Determines whether the package contains a metadata property with the specified name.
`find_properties(self, specification)`	Finds the metadata properties satisfying a specification. The search is recursive so it affects all nested packages as well.
`update_properties(self, specification, value)`	Updates known metadata properties satisfying a specification. The operation is recursive so it affects all nested packages as well.
`remove_properties(self, specification)`	Removes metadata properties satisfying a specification.
`add_properties(self, specification, value)`	Adds known metadata properties satisfying the specification. The operation is recursive so it affects all nested packages as well.
`set_properties(self, specification, value)`	Sets known metadata properties satisfying the specification. The operation is recursive so it affects all nested packages as well. This method is a combination of `MetadataPackage.add_properties` and `MetadataPackage.update_properties`. If an existing property satisfies the specification its value is updated. If there is a known property missing in the package that satisfies the specification it is added to the package.
`sanitize(self)`	Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
