Fit point spline, change green tangent circle side

Anonymous — Tue, 30 Nov 2021 18:37:12 GMT

Hi All,

I hope this is a fairly simple question but I can't seem to find the solution anywhere.

How can I change the side the green tangent circle is at? Whatever I do it stays at the "top" side but I want it at the "bottom" side, so the curvature would be in the other direction.

The Spline Curvature Handle will ALWAYS be on the inside curve of a point on the spline. If you want it on the opposite side, you will have to turn off the Curvature Handle, adjust your spline at that point so the inside of spline curve is on the opposite side, then reactivate the Curvature Handle.

Hi,

Thanks for the reply, The problem I face is that my fit point spline only has 2 points. So I don't completely grasp what the inside in that case would be. the goal I try to achieve is to connect the diagonal line with the horizontal line in a somewhat smooth way. Bellow I've attached a picture of the complete sketch. I try to achieve the same curve as the spline on the bottom left but then from diagonal to horizontal.

if there is a better way of doing this I am open to suggestions.

Please attach your Fusion 360 model, which includes the sketch. My first guess is to add a third point to your spline because a spline with only a beginning and end is not very useful. If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section of a forum post to attach it.

By the way, please reply to the person you want to read your message next time, not to yourself.

Hello,

please find the model attached.

In your case, if I am understanding the curve you desire, is to continue to use a two point spline and use the handles, not the curvature handle to get what you desire. Handles will accept sketch constrains just like sketch lines so these can be used to give the natural curve you desire. Model is attached.

Thank you for the help.

What is was hoping is that the line would arc in the other direction, but after some more experimenting and thinking after you said that this was the smoothest line you will get, I figured that the thing I was expecting was impossible. if I lower the height so to speak I get the outcome I expected.
