NXOpen Finding U and V Direction Edges of a Face

NXOpen Finding U and V Direction Edges of a Face

NXOpen Finding U and V Direction Edges of a Face

(OP)
Dear Forum,

I've developed some NXOpen code to Enlarge a face using the CreateEnlargeBuilder. However, that is not my issue. Sometimes, I need to enlarge along the V-direction and sometimes along the U-direction. The face that I am enlarging has multiple saddles and valleys therefore I can't just look at the centroid's U and V direction. I need someway of looking at the edges of the face and get some sense which edges are associative with the U and V directions.

Any Ideas??

Thanks,

RE: NXOpen Finding U and V Direction Edges of a Face

Calculate a couple of points on the edge you're interested in. Then, calculate the (u,v) parameters of these points. Compare the (u,v) values to determine whether u or v is constant along the edge.

To get the (u.v) values of a given point, P, I would use Snap.NX.Face.Parameters(P). I think there's a similar function in NX/Open, but I can't remember what it's called.

.AskFaceParm is one function that will return a U,V parameter, given a point location.
