Conclusion
LibreOffice Draw’s ability to open and edit Visio documents serves several purposes. It is good for preserving Visio documents. Elements from a Visio diagram can be copy and pasted into a report open in a word processor. Draw’s free-drawing tools can be used to enhance a diagram or flowchart.
An organization or individual may no longer have a copy of Visio. There may have changed diagramming applications. They may have stopped producing drawings themselves. Yet they still may have a need to keep old Visio documents readable well into the future. Draw can be used to open, edit, and convert those documents to open formats that are more accessible.
Sometimes it’s important to include a diagram (or part of one) in a report. Screenshots can be taken, but the resulting image may not be as clear as the vector-based elements created in Visio. Draw has the tools to combine various elements of a diagram, so it can easily be copy and pasted into a Writer or Word document.
Draw gives users the ability to create flowcharts and diagrams, but it also is designed with graphic artists in mind, as well. Visio was not designed for artists. A Visio diagram or flowchart can be enhanced by a graphic artist in Draw.
The ability of LibreOffice to open and edit Visio formats is useful. While most people may not choose to replace Office with it for this reason, this gives people more of a reason to include it in their toolbox of applications.
