I'm new to QGIS and longish in the tooth, so please be kind.

I used the measure tool, and the lines measured show up in my project even with all my layers deselected. I can find no additional data in the attribute tables of all the layers.

I have tried select features but to no avail.

  • Measure tool draws temporary lines onto the map canvas. They disappear when you click another tool. Commented Jan 20, 2023 at 15:56

The measure line will disappear when :

  • you close the measure tool window or
  • when you click on the "New" button of the measure tool window or
  • When you select another tool.

It's independent of layer visibility.

    Be aware that after closing the measure tool, clicking the map canvas will re-open it, unless you have first selected another tool (such as pan or select).
