Hi Allan, in the future I might try to set up something like that using a history mechanism, where the points that were used for a "Curve through points" would be adjustable later on.

The alternate point type that Rhino uses tends to not be very useful, it tends to cause a lot of wiggles in the curve when you move around those alternate style points. That's why I have not focused any effort on trying to do those particular ones in MoI.

If you want to have the points for a "Curve through points" to be present, maybe one solution would be to draw in point objects beforehand, and snap on to those while drawing. Then you will have those point objects still around as markers.

To draw a point object in MoI, go to Draw curve > More > Point:




You can use that command to put in points which can act as persistent markers to snap on to a particular point again later on.
