Section - Fillet Bridge

Section - Fillet Bridge

Section - Fillet Bridge

(OP)
Maybe times when I create a face using Section/Fillet-Bridge the result is twisted.
There are no direction arrows that show when selecting the Start and End edges or faces.
How can I prevent the twisting and get it right every time?
I am on NX8.5.3.3

RE: Section - Fillet Bridge

I've always tried to pick my guides, by starting at "the same end". Say the guides have ends labeled A and B on one, and C and D on the other. If I want A to transition to C, I'd start selecting my first guide near A, and my second guide near C.

Sorry I don't have an image to better explain.

RE: Section - Fillet Bridge

+1 to the above. Maybe to help further explain, pick like you would if your were creating a Through Curves feature between 2 lines and didn't have the capability of reversing the directions of the section strings.

Alternatively, you could try a Soft Blend. You won't be able to dynamically watch the cross sectional shape change or leaning of the created surface change with the sliders, but you can get the same sort of effect by using curvature continuity and adjusting the (if I recall correctly) the Rho and Skew values. Rho will control the flatness (low value) or peaking (high value) and Skew should control the leaning towards one or the other tangent hold curves. The Spine curve will help control the isoparametric alignment of the surface. When I used to use a Soft Blend, I'd typically use one of the tangent hold curves as my Spine curve.

Soft Blend should behave similar to a Bridge Curve would, but with options to affect the full length of the blend surface (down the center of the blend, so to speak). Hope this makes a little sense without images on hand.
