5k nodes was an example. Let's say 300 nodes but in a complex map is hard to select nodes one by one.
What you say in the final is correct. I want to select all nodes in a polyline and move because i saw that is the only solution that nodes are snapping to other objects. When u move n object with select tool it's no snapping to other object.
So the question is - is there any other way to select all nodes in a polyline [like ctrl-a or something

) or i have to select them one by one pressing ctrl with Edit Points Tool [M]?
Or there is another way to move a polyline in a specific exact position? x,y?
To show exactly my case...
I transformed a polygon from Stereo70 to WGS84 but there is an error - about 7 m deviation. So i took a reper point and now i have a polygon (transformed in polyline) with a reper point that i have to move over wgs84 reper point. I can move simple visually with select tool, but i wanted to know if there is a way that the reper point can snap ---> exactly on the other point...
I don't know if you understood me now...
