Need help smoothing splines

[jonathan joseph]

Amateur question I'm sure. I just made a spline using "manual spline" in X8. I drew 7 points to draw the spline through. When done the spline was faceted not smooth. In the past I've done this with no problem. What am I doing wrong? 

Thanks!

Through your sample file up so others can follow along.

Here's the file, thanks for looking at this!

Looking at the points your spline was made from (create Points > Node Points), then creating lines between them reveals that there's an inconsistent angle between the points, which means you're not going to have a "smooth" spline, as it has to conform to each points different.

If this isn't a high tolerance part (and I'm sure it's not as you're only making 9 points across 53"), so I'd recommend just not using the odd points.

In this image, I made the orange spline by only using the points from the points indicated by arrows.  Much smoother as it doesn't "tuck in" to hit the points not on the "arc" that I want to hit.

Aaron, thank you very much for the suggestion. Sorry to not have followed up sooner. I appreciate all the help here.
