Second derivative continuous,

Wayne K

How can I verify that a Fitted Spine line created in CADfeko is a 2nd derivative continuous line?

I need to make sure that ‘FittedSpline1’ in W_L_Input_2GHz_v3_0_30_mesh_45_45_Faster_solver_TUTandBody is a 2^nd derivative continuous line? 

I also need to 2^nd derivative continuous line going from the diagonal line on the loft (‘Loft1’, L_W_R_D_d_T_t_imput_v11_2ndDervativeContunuousLine) to the ‘Bottom’ face. the ends of both lines must have the same tangent as the surfaces that they connecting to.  How would I go about making the line and verify that it is a 2^nd derivative continuous line?

I will need to investigate.

Have you tried the analytical curve? Here you can specify an equation for the curve which of course you have full control over.

I think I could that for W_L_Input_2GHz_v3_0_30_mesh_45_45_Faster_solver_TUTandBody  but I am not sure how I would do that for L_W_R_D_d_T_t_imput_v11_2ndDervativeContunuousLine.  

I am trying to show that line is a second derivative continuous line. Is there a statement in the documentation that states that all Fitted Spline lines are at least second derivative continuous line. Or is there a way to get the line equitation that created that line so I can check to make sure that it is second derivative continuous.

Fitted splines are not necessarily 2nd derivative continuous.
