I am making something with a curve and everything is good but suddenly when I rotate a point all the points rotate with it. How can I make them rotate separately? here is before rotation enter image description here

and here is after rotation enter image description here

  • $\begingroup$ Are you rotating in object mode? Do you have proportional editing disabled? Can you post a screen grab or a blend file? $\endgroup$ – user1853 Dec 23 '14 at 17:05
  • $\begingroup$ @cegaton I am in edit mode,and proportional editing is off $\endgroup$ – Omar Emara Dec 23 '14 at 17:19

    $\begingroup$ Based on the image it looks like you should add more curve points if you want a tight turn. Blender curves will interpolate curve points. $\endgroup$ – Vader Dec 23 '14 at 17:33

    $\begingroup$ Exactly, the actual points are not moving, it is just the interpolated mesh created from those points. Adding another subdivision near the fold would potentially solve this issue. $\endgroup$ – VRM Dec 23 '14 at 17:41

When you are editing curves, selecting the point of the curve also selects the two control handles that define the curve going into and out of the control point. Rotating this selection moves all three and may not give the result you want.

Another property of the curves control point is Tilt, you can see this value under Transform in the properties sidebar N. When using a flat extrusion shape this can 'twist' the extrusion sideways without altering the curve shape.

You need to be cautious with it's use as a large tilt value compared to the next points can give a visible crease.
