I think is it not possible to memorize points that were put in place when drawing with Curve trough points?

I have used Rhinoceros 3d evaluation program, and there exists such possibility: two ways to display curve points.

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.

Hi Allan, here's an example of why that "Edit points" mechanism in Rhino is just not good for actually editing a curve.

Here in Rhino I have drawn a curve through points, and then turned the "Edit points" to be on:



Now look what happens when I move that selected point:




Notice how the curve has become strangely lumpy and bent in the middle, and a strange hook has formed at the end?




When you move those "edit points" in Rhino around, you do not actually get the same result as if you had drawn a brand new curve through those points.

I wanted to add that in to Rhino mostly because there was a mechanism for it in Alias, I didn't really know at the time how bad of an editing tool it actually was going to be.

Thanks for your response, Michael Gibson!

Maybe we could just have a way to visualize these points, not to edit afterwards?

Hi Allan,

Well, frankly that would be kind of weird, because for the majority of users it would not really serve any purpose. It would lead to a lot of questions about "why are you just showing these points and not using them to edit?" ...

If you want to refer back to the "through point" later on, currently the way that you will need to do it in MoI is to place that point in before drawing the curve as a Point object, and snap on to it while drawing the curve.


I do think that in the future at some point with a more complete history editing mechanism it will be possible to do something more directly like what you are asking about, but I'm not sure when that will happen.
