Well, I guess it won't really hurt anything and since it is kind of traditional I put that in as well.

The output of conic is just a regular curve object, so you can adjust it by moving control points around and have a loft update same as for other curves. But currently you won't be able to adjust the rho value afterwards though, since that is not something that you can edit on a general curve object right now.

In the future I do want to make a deeper history mechanism that would allow you to adjust various numeric parameters that went into the construction of an object, which would at that point allow for that kind of tweaking.

It'll be in the next beta. Also I added in a feature that if you snap the ends of the conic on to curves, the intersection point of the curve tangents is available as a tan/tan snap point, like this:

Also that can be used to make an ellipse segment like so:

Also the Rho value will update when you move the mouse around so you can see what Rho value corresponds to the current shape that is defined by the "through point". And also MoI will allow for negative Rho values (normally they are restricted to between 0 and 1) which will produce the ellipse segment bulging from the other side as in the second screencap above.

:) Yup, it's getting pretty close to being wrapped up, kind of in the final stretches here but it always takes longer than I wish to wrap up the final details.
