    Using StudioSplineBuilder in an external application

    I am working on an External NX application using C and C++ API with NX 8.5. I am trying to fit curves and surfaces through some point data that I have. I am adding the points to an array and trying to fit a curve through those using StudioSplineBuilder. I need a NURBS curve so I use...

    Curve fitting using UF_MODL_create_fitted_spline with end slopes

    I am trying to fit a curve using UF_MODL_create_fitted_spline providing end slopes. One end of the created spline shows a loop back due to the slope constraint. I have observed that NX decides the direction of the slope vector automatically. I tried negating the slope vector but still it causes...

    What change does the sewing operation do to a B surface?

    What change does the sewing operation do to a B surface? I am using UF_MODL_create_sew to sew two surfaces. But when I query the target surface for knots and control points using UF_MODL_ask_bsurf before and after the sewing operation I see no difference. So I am not sure if I have the right...

    Error in Visual Studio 2010 with NX8.5

    Visual Studio 2010 behaves in a weird manner. I have a function to extract control points from a surface in which i use UF_MODL_ask_bsurf(). Sometimes VS executes past the code line and prints the control points on console. Some other times it stops at UF_MODL_ask_bsurf(). I cant figure out...

    Error in getting control points for surface in UF_MODL_ask_bsurf

    I am trying to get control points and other data for a NURBS surface. I am using the UF_MODL_ask_bsurf method. UF_MODL_bsurface_p_t t_struc_info; UF_CALL(UF_MODL_ask_bsurf(SurfId, t_struc_info)); I get the following error without any proper error message or error code...

    Creating a spline and getting its control points (poles)

    Hi, I am trying to create a spline in NXOpen by passing the points on curve and I need to extract the control points for this curve. Which would be the best way to do it? I can use UF_CALL (UF_MODL_create_fitted_spline(&tFitSplineData, &dMaxErr, &nErrorCode, &tGeometry) ); but I dont know...

    Error code 945001

    Hello all, I am trying to create a .dll using NX Open to create surface. I wrote a function which returns the error 945001. I am not able to find out what error 945001 actually is. Below is the function code. This function accepts an array of points and creates a spline from those points and...

    Creating NX Open application (External)

    Hi all, I am into application development using C++. I am new to NXOpen. For my next assignment I am looking to creating an application in C++ using NXOpen libraries. The application is supposed to be external to NX environment (as an independent setup and program launcher). Where should I...
