direction of spline template

Valued Contributor

In a previous thread, @Yamada gave very helpful guidance on spline template.
 
Below is an example. Using Fit Curve, I try to refit "ARC_GREEN" with "SPLINE_BROWN" as the template. No matter how I select the curves, I can never move the knot to the down part on the resulting curve (conincident with "ARC_GREEN"). In other words, I can't reverse the direction of the template.
 
Do I miss something important here?
 
Thanks!

I suspect that the result depends on the parameter direction of the arc, not on where you select it. If I'm correct, then you'll get the result you want if you reverse the direction of the arc. Controlling arc directions is a bit tricky, though.

Hi @Yamada   I just find the solution. Composite Curve can create a copy of the template spline with the reverse direction. Thanks!

 

I think that a "Reverse Direction" tool could be added to the "Select Template Curve" option for all the related features.
