Is there a way to "curve" a straight line? In AutoCAD it was a very simple process. I cannot though find a way to just take a straight line in Blender 2.8 and make it curved between the two vertices?

  • At the moment, the answer to this looks like: 1. Create a Bezier curve 2. in Edit mode, all selected, hit 'V','V'. 3. Hit 'V' again, > Auto, and manipulate control points. But if you're looking for something more specific, could you elaborate? – Robin Betts May 10 '19 at 06:41
  • You could help us by including a screenshot. By "line", do you mean an edge connecting two polygons, a bezier curve, a NURBS curve... ? – Ben May 10 '19 at 08:05
  • Updated. I want to take the line shown by the blue arrow that I have selected and curve it to approximately the curve of the red line.

    I could take and subdivide it and pull each individual subdivision node to where it needs to be but that seems tedious and I'm sure there is a quicker way.

    An edge is a straight line between two vertices. To make a curve will involve subdividing of some form. Proportional edit lets you move one vert and have others in given vicinity drop off in a regular (eg spherical manner). https://docs.blender.org/manual/en/dev/editors/3dview/object/editing/transform/control/proportional_edit.html#edit-mode – batFINGER May 10 '19 at 14:51
  • Gotcha. So there is no easy way (other than subdividing possibly) to just add an arc to an already existing line? – Richard Newman May 10 '19 at 16:05
  • To clarify by way of example, to convert one edge on the default cube to curve. Subdividing just that edge, and by some method arranging in an arc, will lead to 2 ngons (faces sharing original edge). Would that result be Ok? Maybe Somewhat related – batFINGER May 10 '19 at 18:10

    I think what you’re running into is that AutoCAD can have actual circular arcs, trivially, and blender cannot. Different conceptual models. But I’m a total newbie so don’t take my word for it; maybe @RobinBetts can confirm? – Wildcard May 10 '19 at 23:45

You might be able to use the spin tool to create a curved connection enter image description here
