How can I simplify or resample a Bezier curve? When I use the Grease Pencil to draw out quick curves in the 3D Viewport, and then convert the pencil to a Bezier curve, the result is always consisting of very dense geometry and handles which are not aligned very well:

too many control points:



strange concept of handle alignment



Is there a Tool / Addon which can simplify these curves, so they become more smooth, and easier to control afterwards?
You can simplify the curves with an addon called Simplify Curves that can be found and enabled in the settings.

When the addon is enabled you need to select the curve that you want to simplify, then hit Space bar button and type simplify curves in the search field.



Once you selected the function, by bringing operator menu with F6 button or in the operator panel you will be able to change the amount of smoothing.



Once you get the desired result, change the Shape of the curve to 3D in the Curve Settings panel.
