how to draw an auto-rescaling connector between two objects?

I’m new to blender, and I’m trying to model two sphere objects and connect them with a line that will automatically shrink, grow, and rotate to keep the spheres connected as I move them. It doesn’t matter to me if the line is a curve, a cylinder object, or something else as long as it is visible. I want to be able to move each sphere independently without changing the position of the other sphere. It seems like this should be as simple as drawing a curve and having each endpoint be set to the location of the origin of the spheres, so that the line will automatically move when the origin moves, but I can’t figure out how to do this. Any insights?

Seems like I am not the only one:

I answered back on your topic :wink:

See you :slight_smile: ++

You could also use curve with two vertices, set their handle types to “vector” and then hook the vertices to your objects with the hook modifier.

Then give the curve some geometry.

Unfortunately, I was not able to make it work :frowning:

  1. create curve -> bezier curve
  2. enter edit mode and select all vertices
  3. hit v to change handle type and set to “vector”
  4. Select a single vertex and go to “control point” menu -> Hooks -> Hook to new object
  5. do the same with the other vertex
  6. leave edit mode
  7. move the newly created empties to the object you want to attach the curve to
  8. parent the empty to your object
