Spline as reference
Good morning everyone,
I was wondering if there's a way of using a 3D spline (obtained by the intersection of 3 points in the space) as a reference while scaling a NACA profile.
Honestly I have doubts that this is correct since the scaling as reference I imagine would basically destroy the NACA profile.
Now I am currently connecting the 1st and 3rd points using a straight line and then scaling the NACA using its chord (I'm using a symmetrical profile) like others previously recommended me in a post I submitted last month.
Thanks in advance, I truly hope we could figure out a way of doing this in order to obtain a post that'd help people in the future while drawing a turbine blade of similar objects.
M.

Hi @tecnicoKJFRK,
Great question. I am not sure I have seen anyone scale an object by reference to a 3D spline. Given the rather organic form of a NACA profile and some elements that it may be comprised of (for example arcs), I would tend to agree with you.
Maybe create a test copy of your file, try scaling, then compare the results?

What is your goal in using a 3D spline as reference for scaling the NACA profile? Scaling by reference just uses lengths, either specified explicitly or indirectly by the distance between two points, to linearly scale geometry.
