Curvature Continuity
Curvature Continuity
(OP)
What's the best way to make a C2 curve connect two other curves?
Curve through points work. But it's a pain to tweak this curve (at least it in my my version of WF2) - since you can't drag the control points of a C2 you have to go back to just tangency, drag the single control point, and then go back to curvature to see if you like. rinse&repeat until you get a curve you like.
There's got to be a better way.
Cheers!

RE: Curvature Continuity
If both ends of the curve are set to be curvature continuous with other connecting curves then you will have to add some additional interpolation points (otherwise known in ProE as style points). This can be done in the Tweak dialog for the curves by selecting the button to the right (it does not appear to have name) and choosing the "Add" radio button in the "Style Points" section of the dialog.
This should give you the ability then to tweak a curve in which both ends are curvature continuous.
Hope this helps,

RE: Curvature Continuity
are you able to move added point and refine the C2 curve?
thanks

RE: Curvature Continuity
more specifically:
insert/model datum/curve
thru points(default)/done
spline(default)/whole array (default)
select the two curve end pionts I'm trying to C2 connect/done
tangency/make both end points tangent to curves
curvature/then i can select the curvature check box
after that, i'm locked into that curve. even after trying you r technique of changing the spline type in 'tweak'
thanks again!
RE: Curvature Continuity
The error message I received when trying to tweak the curve was this: "Tweak can only be performed on a spline curve through two points."
So it appears that if you want C2 continuity between your array of points and the two other curve (or edges) you will have to create two additional spline curves at both ends of the point array.
