Hi - I have searched the internet for this but i can only see answers as they relate to Nik Collection or Photo Lab 5.
What are these lines and how do you use them? If I click e.g. a rectangle I get 4 lines on the image - but what then? If I right click one of the circles on the line I just get the right-click on the image menu.
If there is just a link to some documentation that would be great.
These lines are for perspective corrections. You seem to have activated PC according to what I see in the advanced history panel.
In order to see the PC tool panel, you have to deselect the local adjustment filter button at the upper end of the right sidebar. Click on the “cube” button to filter for tools that relate to perspective corrections. For more information, follow the link posted by @Guenterm or consult the user guide.
