Rail misses the profile, rail is not smooth

Hello,

I'm having trouble trying to create a loft....rail errors!

I read many posts here about this but I am not able to figure out what I'm doing wrong. Help much appreciated!

You will have to attach your model if you would like the forum users to take a look. If you do not know how to attach your model, open it in Fusion360, select the File menu and then choose Export and save the .F3D file to your hard drive. Then use the Attachments section of a reply forum post to attach it.

Thanks! But I tried attaching and even that came back with an error....it won't let me attach either the fusion file or even a screenshot!

One thing that catches my eye immediately is the splines with way too many spline points. You can probably use less than 1/4 of those to get much better curvature. As you can see in the image below, the curvature comb shown is a wavy mess.

The UI tells you exactly where the problem is:

adding a tangent constraint there between the two curves will help correct that problem
