Hi Iwan, I'll add some more quick comments here.

> Is there a rebuild function in or planed for curves & surfaces ?

There currently isn't a "rebuild with x points" function. I do plan on having one, but I'm not quite sure when it will get in there it possibly might not make it for the V1 release.


> Is there a way to fuse 2 points into one ?

For 2 adjacent points in a single curve you can do this by selecting the point you don't want and deleting it.

If you want to fuse the endpoints for 2 separate curves together you can do this by selecting the curves and using Edit/Join. After joining they will share a single point where the segments meet. If you want to smooth out that point, select the join point and delete it.

If you delete the shared point where 2 segments meet it will fuse the segments together into a single segment.

There are a couple of different ways - one way is to draw a new curve at the end of the one you want to continue, then join it and delete the join point to fuse the segments together.

Another way is to stretch out the last control point of the curve you way to continue, then use Edit/Add pt to insert a bunch of new points behind the last point and then move those new points around.

No, not currently. It will probably be possible in the future at some point when there is more of an interface for editing the history of an object.

There is a way to manipulate a single point on a curve though, which may be useful to you - if you turn on control points on a curve, when the curve is unselected you can click and drag directly on a spot on the curve (instead of on a control point) - this will drag that point "on the curve" to a new location. Kind of like a quick mini single "through pt" adjustment. But it will only fix just that single point, it won't keep it forced through the other "through points" that you picked earlier. Still it is a useful trick for making a curve touch something specific at a certain area. It's also useful for kind of "roughing out" the shape of the curve since it is also a way to move multiple nearby control points in one action. This works when the main curve is unselected - if the main curve is selected then clicking and dragging on it drags the whole curve around.

Let me know if you need more info on any of this.
