Vertex selection from isoparm

Given a NURBS isoparm, is there a way through mel to select the corresponding CVs or Hull? or vice versa?

Thanks

I'm afraid that's it will be impossible to do so. Because CVs doen't lay down directly on isoparms.

The only thing you coud do is to look for the nearest CVs in U or V and select it.

well, within the API it's very possible. If you query the current selection list then use MItGeometry to iterate over the components then reselect, you will have the isoparms converted to CV's.

Annoyingly i could never suss out how to actually iterate over the isoparms within the API.....

Well your both talking abit around eachother without realizing it.

Its both doable in mel and in the api, both solutions have the same problem. Wich the second poster was trying to hint to (actualy i would do the same). He just chooses to call the answer no just beacuse it sint realy EXACTLY whats asked for, becaus it is UNDOABLE without altering geomerty, or a special circumstance applies (the question wasnt realy for a allmost answer but thats the closest thing to yes there is and its pretty close).

Its one of those nimvitty comments where its true but a unfair answer,

Namely, you can select any isoparam EVEN those isoparams that lay inbetween two sets of hulls. Even api cant directly select things that ARENT there.

Instead what you do is you look up what is the closest iosparam that corresposnds to the curve parameters point and choosews that. The mission is moot if you can asume that the user onlly selects isoparams that have corresponding hulls, but thats not REALY a solutiona as you cant asume that.

ITs the exact same thing, only more fault tolerant.

But it still does not answer what to do if someone chooses a isoparam that exactly midway between two hulls? Select oth or none?

Also theres allways the option to insert a isoparam and choose those points but ist usefullness would be a bit questionable (better to make a function for exsisting points, everyone can isnert a isoparm, then jsut call the select routine ad be done with it, more modular thatway)
