I need to rotate a lot of closed curves to align them, and the mouse is quite slow and inaccurate…
How many individual curves do you need to rotate and how would you set the center of rotation without the mouse?
Could be done with a script or Grasshopper…
If you need help, post a file with the relevant geometry and a sketch of the desired result.
Maybe Orient might help here?
With Object Snaps enabled, it is as accurate as it gets.
I ended up using the Rotate command and then snapping the points in question to their desired locations.
