Blending curve to curve
Blending curve to curve
(OP)
Hi Guys,
It’s a very basic question but I can’t figure it out. Please see the attached picture. I am trying to produce a fan blade and want to extrude 1st curve and blend into the 2nd curve.
We are using NX 8.5 and on a basic licence.
Thank you
Regards Rodney

Select profile1, then click "add new set" ( or middle mouse click) then select profile2 . Make sure you select the profiles "consistently".( i.e "same" curve and same end of both curves) You will then avoid confusion
You can then play around with the options in the dialog to get the desired shape.
Regards,
Tomas

In the example : alignment by points which is fully ok, but ... If one looks at the two sides of the model, the concave side shows two faces whilst the convex side only 1 face. In my view would like to have a similar topology here, i.e total of 3 faces "around" instead of 2. The reason is that the resulting surfaces will be much simpler than if one of the 2 faces has to "manage" both the relatively flat and at the same time the relatively tight curvature, plus the transition between.
Edit the feature, turn on "Preserve shape" and set the alignment option to "parameter".
For us nerds:
Original face : 3x3 degree / 28x1 patches
preserve shape + parameter 4x3 degree / 1x1 patch and 4x3 d. / 3x1 p.
