Next question from a total beginner..

Here is two images of the same thing seen from two angles.

How to i align the two sharp edges to the imaginary point between the two vertices (marked with a face/edge in white)

Is the only option to grab them manually and drag them in place, or is there a smarter way?

Your goal is not fully specified by the imaginary line.. the sharp edges could be flattened to any plane that contains it.. (they could be twisted at any angle around the line)

If there is a plane you want to flatten to:

  • In the Pivot Center menu in the header, select 'Active Element'
  • Select three vertices which define the plane (possibly including the ones at the ends of your imaginary line)
  • Hit Ctrl Alt Space to create a Custom Orientation from them, checking 'Use after Creation'
  • Select the edges you want to flatten, and then, in vertex mode, one of the vertices that defined the plane
  • Hit S Z Z 0 to scale the edges onto the plane.
  • $\begingroup$ Can you elaborate on the "set pivot to active"? i dont know how to do that, in fact i dont know what that means ;) I dont have a plane, but guessing i can construct it based on the imaginary line, or two $\endgroup$

  • $\begingroup$ @Stig The Pivot Center selector is 2 to the right of the Edit/Object... Mode selector. Or you can hit keyboard '.'(period). $\endgroup$

  • $\begingroup$ thanks - didnt know that menu - the period '.' on the numeric is zoom, '.' on normal part of keyboard does nothing as far as i can tell. $\endgroup$

  • $\begingroup$ The custom orientation is already defined by the verts/edges/faces you have selected when you invoke it. The tool region/F6 panel give you options to name it, use it after creation, (by hitting the constraint key twice, the ZZ in the answer) or arrange for it to overwrite previous ones so as not to accumulate a huge list of them. Sorry about the '.' .. I have pie menus enabled, some of the shortcuts are different. $\endgroup$
