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.
