OrientOnSrf almost never seems to give me a good result. Orient3Pt works great but its only good on planar surfaces… Otherwise you have to project something onto an organic surface kindof near where you want to orient the part for snapping, and then it’s only an approximation… usually this is good enough for my purposes.
Just curious if there is a technical reason we don’t have Orient3ptOnSrf? Or some other method I’m not aware of.
Hi Ryan - Just off hand this seems like a reasonable idea to me - that is, set the base plane for OrientOnSrf by three points, and the target orientation as a tangent plane set by Origin, X and Y directions, rather than the current (and not always clear to the user) way of using two points and the CPlane normal.
@dale - what do you think?
@wynott - do you need to set the target plane other than as a tangent plane on the surface? If so, we might be out of luck as far as the morphing part goes, but the idea of setting the base plane from 3 points makes a lot of sense.

Thought I would jump in on this. Could a point be placed on the desired surface and then a type of three legged widget (cone)orients itself to the surface creating the perpendicularity needed to place the curve? Might be over my head on this. —Mark😕
Hi Ryan,
Orient3Pt works great but its only good on planar surfaces…
I agree. as a work around I’m using “PersistentOnSurface” command for the Target points of “Orient3Pt” cmd.
but it’s annoying with the copy option.
and I have a Wish for “OrientOnSrf”, add “Undo Option” in command. Please…

Not sure I follow exactly but ideal situation would let me just pick two surfaces and Rhino kindof did its best, sortof like how the real world would work. Like if I was putting a light fixture with a flat base in a concave roof surface, I could pick the flange of the light and the roof and then it would orient the best it can… Which may leave some parts not touching. Make sense? Or putting a cleat on a round deck. Pick cleat mating surface, pick deck. Move to spot.
