Closing a Document When Saving a Copy

original document. If the original document has unsaved changes, the document remains
open.
To close the document when saving a copy:
1. Open a model and click File > Save As.
2. In the Save As dialog box, click Save as copy and open and click Save.
3. When prompted by the Save as copy and open message, select Close the original
document.

Improved Performance When Opening and Saving Files
from a Previous Version
In SOLIDWORKS 2020, most assemblies and drawings, that were saved in a previous
version, open nearly as fast as those saved in SOLIDWORKS 2020. Also, you can make
greater use of lightweight components and drawings without needing to convert them to
the current version.
Previously, some assemblies and drawings, which had not yet been saved in the current
version, took longer to open and save. This was particularly true for assemblies and
drawings with reference components in multiple configurations.
A system option, Force referenced documents to save to current version under
External References improves save performance. When you clear the option, only
documents that have been modified in the current session are saved to the current version
