    NX8 DatumAxis normal to a curve

    Thank you Bubbak, i did exactly the same thing. Tangent vectors works like a charm for this matter.

    NX8 Create X,Y,Z expressions of a selected point

    Yes it is much better since it halves the required measurements. Than you Taylor.

    NX 8 Wrap on a Curved Surface

    I put a screenshot of what i am saying. I want to wrap a planar airfoil to a curved revolve surface. I tried coordinate conversion. I put 100-200 points on the planar airfoil then convert it to the points on the curved surface. But throughpoint spline is not good enough to match the initial...

    NX 8 Wrap on a Curved Surface

    Hello, Wrap command works only on cylindrical or conical surfaces, is there a way to wrap on a revolved curve? Say i have a spline and i revolved it. Is there a way to wrap another curve onto this surface?

    NX8 Create X,Y,Z expressions of a selected point

    By the way there is an issue in the formulas you sent. sgnX = if((p30-p36)>0)(1)else(-1) , {p30 is distance to absolute YZ plane, p36 is distance to ref plane} The sign formula gives negative x coordinate even if it is positive when the point is between the origin and the ref point. For example...

    NX8 DatumAxis normal to a curve

    Is this rule also applied to the tangent vector? Is tangent datums follow any convexivity rule?

    NX8 DatumAxis normal to a curve

    Thanks for the reply jhon. Then i guess the only way to do this is to put some associative rules by measurement etc. Maybe reversing the direction depending on angle measurements or such.

    NX8 DatumAxis normal to a curve

    Hello, I created a point-set on a curve, and put datumaxes on these points normal to the curve (all of these are associative). When i change the curve shape, the datum axes are reversing due if their basepoints are on a concave or convex curvature. Is there a way to prevent this? I put the...

    NX8 Create X,Y,Z expressions of a selected point

    Thank you very much cowski, i think this will solve the issue.

    NX8 Create X,Y,Z expressions of a selected point

    For addition, say i created a point set on a curve, and i want the xyz expressions of all the points of that pointset. That i can not do.

    NX8 Create X,Y,Z expressions of a selected point

    Thanks for reply, It only creates xyz expressions if the point is created due to its xyz coordinates. When i put a point on a curve by percentage, the only expression created is that percentage.

    NX8 Create X,Y,Z expressions of a selected point

    Hello, I want to create associated X,Y,Z expressions of a selected or created point. In one of the posts in the forum, JhonRBaker said in NX 9 there's a function named "Measure Point" to do this. Unfortunately we don't have NX9 in my company. Is there any way of doing this in NX8. For example...

    NX8 Associative Measurement to set expression value

    I figured out the solution. DatumAxis x1; x1 = Functions.CreateDatumAxis(workPart, Camber.CamberSpline, 50, "datum1"); DatumAxis x2; x2 = (DatumAxis)workPart.Datums.FindObject(ABSCSYS.JournalIdentifier.ToString() + " X axis"); Measure a; a =...

    NX8 Associative Measurement to set expression value

    Hello, I am writing a journal to create an airfoil geometry which set by expressions. The journal will be used 1 time to set the geometries and expressions, after that the geometry changes will be made only by the expressions. My question is, is there a way to define an associative vector...
