Let’s say I create a curve: Add->Curve->Path, then I accidentally manage to hit Object->Convert To: -> Mesh From Curve.
I Convert it back using, …->Curve From Mesh, and I do this immediately, without making any other changes to the curve.
Alas, it now has dozens of control points - highly unmanageable. I only needed the default 4. I know it is mathematically possible to describe the curve with the original control points the curve has not been modified, but I have NO idea how to get them back.
I hope I’m not overusing my welcome by asking two posts in one day but thank you kindly for any help.
Could also reduce the number of vertices to have the count of control points in the original path, select menu -> checker deselect, ctrl+i to invert selection and X -> dissolve vertices might come handy. Then convert to curve, edit mode, set spline type to NURBS (tool shelf) and enable active spline options again from curve properties.
Might be good thing to make a duplicate before converting, and you can use resolution options in curve properties to reduce complexity in the resulting mesh.
but thank you kindly for any help.
