Right-click on the line/edge which you want to define as the rotation axis.
-> The corresponding context menu opens.
Select the command Attributes -> Rotation axis.
-> The initially red marked line/edge then shows up as dotted line axis and in the Sketch history beside the feature which is containing the rotation axis, a respective icon is displayed.
First take over these changes by pressing the Sketch OK
button.
