Release Notes - Tekla Structures 2020 SP5

2020 SP5: New features and improvements

In addition to fixes, Tekla Structures 2020 SP5 delivers useful improvements: Document managertool that is used for listing and managing drawings and other types of documents

With the document manager the user can, for example, reorganize, update, freeze, lock, and delete drawings.

The user can also organize file documents, such as PDF, NC, and DWG files, and drawings, in document categories, and search documents and open drawings.

Document manager is replacing drawing list from the version 2018i onwards.
