Hi Pilou, can you please post an example 3DM file that has the curves in it that you're trying to rebuild?
There are 2 modes to Rebuild - either fitting to a distance tolerance or rebuilding by a specified number of points.
If you're using refit to tolerance mode, a straight line will be fit exactly by another straight line so there will be only 2 control points in that mode.
If you use number of points mode, then it will use exactly the number of points that you specify, including on lines.
That makes it possible to use Rebuild for some kinds of cases like when you want to replace simple lines with curves that have more points in them to be able to deform them, like this for example:
So notice there how rebuilding the simple line structure with more points (using number of points mode) made it easier to deform the rectangle into a more wiggly shape.
If you want straight lines and flatter areas to have fewer control points, then use the Refit to tolerance mode instead of "number of points" mode - the fit to tolerance is adaptive and will use less control points in flatter areas of curves and put in more points in curvy areas until the new curve is within the specified distance tolerance of the old one.
