I looked at that file. Noticed it used the "more points" through the curve area, then dropped off at the line segment (which the rebuild doesnt do) though having both will be nice, to be able to fit an exact number of points when desired. Very nice.

I did notice, with the 3 curves you sent back....I did a coons patch with network and noticed that the picking can control the direction! Can you elaborate on this a bit to clarify it for me? I could figure it out with those three curves and place it where I want, but didnt grasp what it was doing, in case there were some different types of curves involved. :O

Thanks.
