Changes in cloned views

When cloning single part, assembly or cast unit drawings, if the cloning templatemaster drawing where an existing drawing is used to copy the drawing settings for a new drawing

The new drawing has the same drawing settings as the original drawing.

The user creates a cloning template of a drawing typically after extensive manual modifications have been made in the drawing, in order to achieve the same appearance and contents in new drawings.

In the master drawing catalog, it is possible to create single-part, assembly, and cast unit drawings using cloning templates. It is also possible to add new cloning templates to the master drawing catalog from the document manager.
