The Measure tool is one of those features that you always need around. So why not keep it open as you work? SOLIDWORKS 2019 enhances the Measure tool so it can remain open while working in other tools. This applies to any tool in Part, Assembly or Drawing environments!
With another tool open, the Evaluate tab will now show Measure is available. You can keep the Measure window open when switching between tools, features, parts/assemblies/drawings and it remains accessible.
If you have the Measure tool open on screen and want to perform other tasks, like right-click on components to open, it may try to keep measuring items. No worries, just right-click and choose ‘Select’. This will make the Measure window inactive until you click it again.
